Installing the Odoo Development Environment
In this chapter, we will cover the following topics:
- Easy installation of Odoo from source
- Managing Odoo environments using the start command
- Managing Odoo server databases
- Storing the instance configuration in a file
- Activating the Odoo developer tools
- Updating Odoo from source
There are lots of ways to set up an Odoo development environment. This chapter proposes one of these, although you will certainly find a number of other tutorials on the web explaining other approaches. Keep in mind that this chapter is about a development environment that has requirements different from a production environment, which will be covered in Chapter 3, Server Deployment.
Easy installation of Odoo from source
For Odoo deployment, it is recommended to use a GNU/Linux environment. You may be more at ease using Microsoft Windows or Mac OS X, but the fact is that most of the Odoo developers are using GNU/Linux, and you are much more likely to get support from the community for OS-level issues occurring on GNU/Linux than on Windows.
It is also recommended to develop using the same environment (the same distribution and the same version) as the one that will be used in production. This will avoid nasty surprises such as discovering, on the day of deployment, that some library has a different version than is expected, with slightly different and incompatible behavior. If your workstation is using a different OS, a good approach is to set up a virtual machine on your workstation and install a GNU/Linux distribution in the VM.
This book assumes that you are running Debian GNU/Linux as its stable version (this is version 9, code name Stretch at the time of writing). Ubuntu is another popular choice, and since it is built on top of Debian, most of the examples in this book should work unchanged. Whatever Linux distribution you choose, you should have some notion of how to use it from the command line, and having a few ideas about system administration will certainly not cause any harm.
We assume that Linux is up and running and that you have an account with root access, either because you know the root password, or because sudo has been configured. In the following pages, we will use $(whoami) whenever the login of your work user is required in a command line. This is a shell command that will substitute your login in the command you are typing.
Some operations will definitely be easier if you have a GitHub account. Go to https://github.com and create one if you don't have one already.
How to do it...
To install Odoo from source, you need to follow these steps:
- Run the following commands to install the main dependencies:
$ sudo apt-get update
$ sudo apt-get install -y git python3.5 postgresql nano virtualenv
\ xz-utils wget fontconfig libfreetype6 libx11-6 libxext6 libxrender1 \ node-less node-clean-css xfonts-75dpi
- Download and install wkhtmltopdf:
$ wget -O wkhtmltox.tar.xz \ https://github.com/wkhtmltopdf/wkhtmltopdf/releases/download/0.12.4/wkhtmltox-0.12.4_linux-generic-amd64.tar.xz
$ tar xvf wkhtmltox.tar.xz
$ sudo mv wkhtmltox/lib/* /usr/local/lib/
$ sudo mv wkhtmltox/bin/* /usr/local/bin/
$ sudo mv wkhtmltox/share/man/man1 /usr/local/share/man/
- Now, use this to install the build dependencies:
$ sudo apt-get install -y gcc python3.5-dev libxml2-dev \
libxslt1-dev libevent-dev libsasl2-dev libssl1.0-dev libldap2-dev \
libpq-dev libpng-dev libjpeg-dev
- Configure PostgreSQL:
$ sudo -u postgres createuser --createdb $(whoami)
$ createdb $(whoami)
- Configure git:
$ git config --global user.name "Your Name"
$ git config --global user.email firstname.lastname@example.org
- Clone the Odoo code base:
$ mkdir ~/odoo-dev
$ cd ~/odoo-dev
$ git clone -b 11.0 --single-branch\ https://github.com/odoo/odoo.git
$ cd odoo
- Create an odoo-11.0 virtual environment and activate it:
$ virtualenv -p python3 ~/odoo-11.0
$ source ~/odoo-11.0/bin/activate
- Install the Python dependencies of Odoo in virtualenv:
$ pip3 install -r requirements.txt
- Create and start your first Odoo instances:
$ createdb odoo-test
$ python3 odoo-bin -d odoo-test --addons-path=addons \
- Point your browser to http://localhost:8069 and authenticate it using the admin account and admin as password.

How it works...
Dependencies come from various sources. First, you have the core dependencies of Odoo, the Python interpreter that is used to run the source code, and the PostgreSQL database server used to store the instance data. Git is used for source code versioning and getting the source code of Odoo itself.
Since we will need to edit some files as root or as postgres (the PostgreSQL administrative user) on our server, we need to install a console-based text editor. We suggest nano as it is very simple to use, but feel free to choose any editor with which you feel at ease as long as it works on the console, such as vim, e3, or emacs-nox.
Wkhtmltopdf is a runtime dependency of Odoo used to produce PDF reports. The version required by Odoo 11.0 is 0.12.4, which is not included in the current GNU/Linux distributions. Fortunately for us, the maintainers of wkhtmltopdf provide pre-built packages for various distributions on http://wkhtmltopdf.org/downloads.html.
There are lots of other runtime dependencies that are Python modules, which we can install using pip3 in a virtual environment. However, some of these Python modules can feature some dependencies on native C libraries, for which the Python bindings need to be compiled. Therefore, we install the development packages for these C libraries as well as the Python development package and a C compiler. Once these build dependencies are installed, we can use pip3 install -r requirements.txt (a file that comes from the Odoo source code distribution) to download, compile, and install the Python modules.
Python virtual environments, or virtualenv for short, are isolated Python workspaces. They are very useful to Python developers because they allow different workspaces with different versions of various Python libraries to be installed, possibly on different Python interpreter versions.
You can create as many environments as you wish using the virtualenv -p python3 path/to/newenv command. This will create a newenv directory in the specified location, containing a bin/ sub-directory and a lib/python3.5 subdirectory. Don't forget -p python3, or you are likely to get a python 2.7 virtual environment that will not be able to run Odoo 11.0.
In bin/, you will find several scripts:
- activate: The script is not executed; it is sourced using the shell built-in source command. This will activate the environment by adjusting the PATH environment variable to include the bin/ directory of the virtualenv. It also installs a shell function called deactivate, which you can run to exit the virtualenv, and changes the shell prompt to let you know which virtualenv is currently activated.
- pip3: This is a special version of the pip3 command that acts inside the virtualenv only.
- python3: This is a wrapper around your system Python interpreter that uses the packages installed in the virtualenv.
There are two main ways of using a virtualenv. You may activate it as we show in the recipe (and call deactivate when you're done), or you may use the scripts in the bin/ directory of the environment explicitly by calling them with their full path, in which case you don't need to activate the virtualenv. This is mainly a matter of taste, so you should experiment and find out which style suits you better for which case.
You may have executable Python scripts with the first line looking like the following:
#! /usr/bin/env python3
These will be easier to use with an activated virtualenv.
This is the case with the odoo-bin script, which you can call in the following way:
$ ./odoo-bin -d odoo-test --addons-path=addons --db-filter=odoo-test
On a GNU/Linux system, Odoo works very well with the default values of psycopg2 that the Python module used to access a PostgreSQL database:
- Passwordless authentication if the database user has the same name as the current user on local connections
- Local connection uses Unix domain sockets
- The database server listens on port 5432
In that case, there is nothing special to do; we use the postgres administrative user to create a database user who shares our login name and gives it the right to create new databases. We then create a new database with the same name as the new user, which will be used as a default database when using the psql command.
When on a development server, it is okay to give the PostgreSQL user more rights and to use the --superuser command-line option rather than just --createdb. The net effect is that this user can then also create other users and globally manage the database instance. If you feel that --superuser is too much, you may still want to use --createrole in addition to --createdb when creating your database user. Avoid doing this on production servers as it will give additional leverage to an attacker exploiting a vulnerability in some part of the deployed code (refer to Chapter 3, Server Deployment).
If you want to use a database user with a different login, you will need to provide a password for the user. This is done by passing the --pwprompt flag on the command line when creating the user, in which case the command will prompt you for the password.
If the user has already been created and you want to set a password (or modify a forgotten password), you can use the following command:
$ psql -c "alter role $(whoami) with password 'newpassword'"
At some point in the book, you will need to use git commit. This will fail unless some basic configuration is performed; you need to provide Git with your name and email address. Git will remind you to do this with a nice error message, but you may as well do it now.
Downloading the Odoo source code
Downloading the Odoo code base is done by performing a git clone operation; be patient as this will take some time. The --branch 11.0 --single-branch options avoid downloading other branches and save a little time. The --depth option can also be used to avoid downloading the whole repository history, but the downside of that option is that you will not be able to explore that history when looking for issues.
Odoo developers also propose nightly builds, which are available as tarballs and distribution packages. The main advantage of using a git clone is that you will be able to update your repository when new bug fixes are committed in the source tree. You will also be able to easily test any proposed fixes and track regressions, so you can make your bug reports more precise and helpful for the developers.
Starting the instance
Now comes the moment you've been waiting for. To start our first instance, we first create a new empty database and then use the odoo-bin script with the following command-line arguments:
- -d database_name: Use that database by default.
- --db-filter=database_name$: Only try to connect to databases matching the supplied regular expression. One Odoo installation can serve multiple instances living in separate databases, and this argument limits the available databases. The trailing $ is important as the regular expression is used in match mode; this avoids selecting names starting with the specified string.
- --addons-path=directory1,directory2,...: This is a comma separated list of directories in which Odoo will look for addons. This list is scanned at the instance creation time to populate the list of available addon modules in the instance.
If you are using a database user with a database login different from your Linux login, you need to pass the following additional arguments:
- --db_host=localhost: Use a TCP connection to the database server
- --db_user=database_username: Use the specified database login
- --db_password=database_password: The password to use to authenticate against the PostgreSQL server
To get an overview of all of the available options, use the --help argument. We will see much more about the odoo-bin script in this chapter as well as in Chapter 2, Managing Odoo Server Instances.
When Odoo is started on an empty database, it will first create the database structure needed to support its operations. It will also scan the addons path to find the available addon modules, and insert some into the initial records in the database. This includes the admin user with the default password admin, which you will use to authenticate with.
Odoo includes an HTTP server. By default, it listens on all local network interfaces on TCP port 8069, so pointing your web browser to http://localhost:8069/ leads you to your newly created instance.
In the recipe, we downloaded the latest stable version of Odoo using the following command:
$ git clone -b 11.0 --single-branch https://github.com/odoo/odoo.git
This uses the official branch maintained by Odoo. One issue with this branch is that bug fixes contributed by the community are not always merged in a timely fashion. The Odoo Community Association (OCA) maintains a parallel branch in which fixes and improvements are peer-reviewed by the community and tend to be merged faster than on the official branch. It is not a fork of Odoo, and the latest version of Odoo is merged back into that branch daily. You may want to use it for your developments and deployments, in which case you need to clone Odoo like this:
$ git clone -b 11.0 --single-branch https://github.com/OCA/OCB.git odoo
Managing Odoo environments using the start command
We will often want to use custom or community modules with our Odoo instance. Keeping them in a separate directory makes it easier to install upgrades to Odoo or troubleshoot issues from our custom modules. We just have to add that directory to the addons path, and they will be available in our instance, just like the core modules are.
It is possible to think about this module directory as an Odoo environment. The Odoo start command makes it easy to organize Odoo instances as directories, each with its own modules.
For this recipe, we need to have already installed Odoo. We assume that it will be at ~/odoo-dev/odoo, and that the virtualenv is activated.
This means that the following command should successfully start an Odoo server:
How to do it...
To create a work environment for your instance, you need to follow these steps:
- Change to the directory where Odoo is:
$ cd ~/odoo-dev
- Choose a name for the environment and create a directory for it:
$ mkdir my-odoo
- Change to that directory and start an Odoo server instance for that environment:
$ cd my-odoo/
$ ../odoo/odoo-bin start
How it works...
The Odoo start command is a shortcut to start a server instance using the current directory. The directory name is automatically used as the database name (for the -d option), and the current directory is automatically added to the addons path
(the --addons-path option), as long as it contains an Odoo addon module. In the preceding recipe, you won't see the current directory in the addons path because it doesn't contain any modules yet.
By default, the current directory is used, but the --path option allows you to set a specific path to use instead. For example, this will work from any directory:
$ ~/odoo-dev/odoo/odoo-bin start --path=~/odoo-dev/my-odoo
The database to use can also be overridden using the usual -d option. In fact, all of the other usual odoo-bin command-line arguments, except --addons-path, will work. For example, to set the server listening port, use the following command:
$ ../odoo/odoo-bin start -p 8080
As we can see, the Odoo start command can be a convenient way to quickstart Odoo instances with their own module directory.
Managing Odoo server databases
When working with Odoo, all of the data of your instance is stored in a PostgreSQL database. All of the standard database management tools you are used to are available, but Odoo also proposes a web interface for some common operations.
We assume that your work environment is set up, and you have an instance running. Do not start it using the odoo-bin start command shown in the previous recipe, as it configures the server with some options that interfere with multi database management.
How to do it...
The Odoo database management interface provides tools to create, duplicate, remove, back up, and restore a database. There is also a way to change the master password that is used to protect access to the database management interface.
Accessing the database management interface
To access the database, the following steps need to be performed:
- Go to the login screen of your instance (if you are authenticated, log out).
- Click on the Manage Databases link. This will navigate to http://localhost:8069/web/database/manager (you can also point your browser directly to that URL).
Setting or changing the master password
If you've set up your instance with default values, and not yet modified it as explained in the following section, the database management screen will display a warning, telling you that the master password is not set and advising you to set one with a direct link:
To set the master password, you need to perform the following:
- Click on the Set Master Password button. You will get a dialog box asking you to provide the New Master Password:
- Type in a non-trivial new password and click on Continue
If the master password is already set, click on the Set Master Password button at the bottom of the screen to change it. In the displayed dialog box, type the previous master password and the new one, and then click on Continue.
Creating a new database
This dialog box can be used to create a new database instance that will be handled by the current Odoo server:
- In the database management screen, click on the Create Database button at the bottom of the screen:
- Fill in the form, as follows:
- Master Password: The master password for this instance.
- Database Name: Input the name of the database you wish to create.
- Password: Type the password you want to set for the admin user of the new instance.
- Language: Select the language you wish to be installed by default in the new database in the drop-down list.
- Country: Select the country of the main company in the drop-down list.
- Load demonstration data: Check this box to have demonstration data. This is useful to run interactive tests or set up a demonstration for a customer, but it should not be checked for a database meant to contain production data.
- Click on the Continue button, and wait a little until the new database is initialized. You will then be redirected to the instance, connected as the administrator.
Duplicating a database
Very often, you will have an existing database and you want to experiment with it to try a procedure or run a test, but without modifying the existing data. The answer is simple—duplicate the database and run the tests on the copy. Repeat this as many times as required:
- In the database management screen, click on the Duplicate Database link next to the name of the database you wish to clone:
- Fill in the form as follows:
- Master Password: The master password of the Odoo server
- New Name: The name you want to give to the copy
- Click on the Continue button
- You can then click on the name of the newly created database in the database management screen to access the login screen for that database
Removing a database
When you have finished your tests, you will want to clean up the duplicated databases. To do this, perform the following steps:
- In the database management screen, click on the Delete Database link next to the name of the database you want to remove:
- Fill in the form; enter the Master Password, which is the master password of the Odoo server
- Click on the Delete button
If you selected the wrong database, and have no backup, there is no way to recover the lost data.
Backing up a database
For creating a backup, the following steps need to be performed:
- Fill in the form:
- Master Password: The master password of the Odoo server.
- Backup Format: Always use zip for a production database, as it is the only real full backup format. Only use the pg_dump format for a development database where you don't really care about the file store.
- Click on the Backupbutton. The backup file will be downloaded to your browser.
Restoring a database backup
If you need to restore a backup, this is what you need to do:
- In the database management screen, click on the Restore Database button at the bottom of the screen:
- Fill in the form:
- Master Password: The master password of the Odoo server.
- File: A previously downloaded Odoo backup.
- Database Name: Provide the name of the database in which the backup will be restored. The database must not exist on the server.
- This database might have been moved or copied: Choose "This database was moved" if the original database was on another server, or if it has been deleted from the current server. Otherwise, choose "This database is a copy", which is a safe default.
- Click on the Continue button.
How it works...
These features, apart from the Change master password screen, run PostgreSQL administration commands on the server and report back through the web interface.
The master password is a very important piece of information that only lives in the Odoo server configuration file and is never stored in the database. There used to be a default value of admin, but using this value is a security liability as it is well known. In Odoo v9 and later, this is identified as an "unset" master password, and you are urged to change it when accessing the database administration interface. Even if it is stored in the configuration file under the admin_passwd entry, this is not the same as the password of the admin user; these are two independent passwords; the master password is set for an Odoo server process, which itself can handle multiple database instances, each of which has an independent admin user with his own password.
To create a new database, Odoo uses the PostgreSQL createdb utility and calls the internal Odoo function to initialize the new database in the same way as when you start Odoo on an empty database.
To duplicate a database, Odoo uses the --template option of createdb, passing the original database as an argument. This essentially duplicates the structure of the template database in the new database using internal and optimized PostgreSQL routines, which is much faster than creating a backup and restoring it (especially when using the web interface that requires downloading the backup file and uploading it again).
Backup and restore operations use the pg_dump and pg_restore utilities, respectively. When using the zip format, the backup will also include a copy of the file store that contains a copy of the documents when you configure Odoo to not keep these in the database, which is the default in 11.0. Unless you configure it otherwise, these files live in ~/.local/share/Odoo/filestore.
Experienced Odoo developers generally don't use the database management interface, and perform the operations from the command line. To initialize a new database with demo data, for instance, the following one-liner can be used:
$ createdb testdb && odoo-bin -d testdb
The additional bonus of this command line is that you can request the installation of addons while you are at it using, for instance, -i sale,purchase,stock (more on this in Chapter 2, Managing Odoo Server Instances).
To duplicate a database, stop the server and run the following commands:
$ createdb -T dbname newdbname
$ cd ~/.local/share/Odoo/filestore # adapt if you have changed the data_dir
$ cp -r dbname newdbname
$ cd -
Note that in the context of development, the file store is often omitted.
To remove an instance, run the following command:
$ dropdb dbname
$ rm -rf ~/.local/share/Odoo/filestore/dbname
To create a backup (assuming that the PostgreSQL server is running locally), use the following command:
$ pg_dump -Fc -f dbname.dump dbname
$ tar cjf dbname.tgz dbname.dump ~/.local/share/Odoo/filestore/dbname
To restore the backup, run the following command:
$ tar xf dbname.tgz
$ pg_restore -C -d dbname dbname.dump
If your Odoo instance uses a different user to connect to the database, you need to pass -U username so that the correct user is the owner of the restored database.
Storing the instance configuration in a file
The odoo-bin script has dozens of options, and it is tedious to remember them all and to remember to set them properly when starting the server. Fortunately, it is possible to store them all in a configuration file and to only specify by hand the ones you want to alter, for example, for development.
How to do it...
To generate a configuration file for your Odoo instance, run the following command:
$ odoo-bin --save --config myodoo.cfg --stop-after-init
You can add additional options, and their values will be saved in the generated file. All the unset options will be saved with their default value set. To get a list of possible options, use this:
$ odoo-bin --help | less
This will provide you with some help about what the various options perform. To convert from the command line form to the configuration form, use the long option name, remove the leading dashes, and convert the dashes in the middle to underscores:
--without-demo becomes without_demo. This works for most options, but there are a few exceptions listed in the next section.
Edit the myodoo.cfg file (use the table in the following section for some parameters you may want to change). Then, to start the server with the saved options, run the following command:
$ odoo-bin -c myodoo.cfg
How it works...
At start up, Odoo loads its configuration in three passes. First, a set of default values for all options is initialized from the source code, then the configuration is parsed, and any value defined in the file overrides the defaults. Finally, the command-line options are analyzed and their values override the configuration obtained from the previous pass.
As mentioned earlier, the names of the configuration variables can be found from the names of the command-line options by removing the leading dashes and converting the middle dashes to underscores. There are a few exceptions, notably the following:
http_enable = True / False
--i18n-import / --i18n-export
Here's a list of options commonly set through the configuration file:
Comma separated list of module names, or all (to disable demo data for all modules) or False (to enable demo data for all modules)
Prevents module demo data from being loaded.
Comma separated list of paths
A list of directory names in which the server will look for addons (refer to Chapter 2, Managing Odoo Server instances).
The master password (take a look at the preceding recipe).
Path to a directory
A directory in which the server will store session information, addons downloaded from the internet, and documents if you enable the file store.
The name of the server running the PostgreSQL server. Use False to use local Unix Domain sockets, and localhost to use TCP sockets locally.
Database user login
Database user password
This is generally empty if db_host is False and db_user has the same name as the user running the server. Read the man page of pg_hba.conf for more information on this.
Used to set the database name on which some commands operate by default. This does not limit the databases on which the server will act. Refer to the following dbfilter option for this.
A regular expression
The expression should match the name of the databases considered by the server. If you run the website, it should match a single database, so it will look like ^databasename$. More information on this is in Chapter 3, Server Deployment.
IP address of a network interface
Defaults to 0.0.0.0, which means that the server listens on all interfaces.
The ports on which the Odoo server will listen. You will need to specify both to run multiple Odoo servers on the same host; longpolling_port is only used if workers is not 0.
http_port defaults to 8069 and longpolling_port to 8072.
Path to a file
The file in which Odoo will write its logs.
Log verbosity level
Specify the level of logging. Accepted values (in increasing verbosity order): critical, error, warn, info, debug, debug_rpc, debug_rpc_answer, debug_sql.
The number of worker processes. Refer to Chapter 3, Server Deployment, for more information.
True / False
Set to True to disable listing of databases. See Chapter 3, Server Deployment, for more information.
Activating the Odoo developer tools
When using Odoo as a developer, you need to know how to activate Developer Mode in the web interface to access the advanced settings menu and developer information.
How to do it...
To activate Developer Mode in the web interface, do as follows:
- Connect to your instance and authenticate as admin
- Go to the Settings menu
- Locate the Share the love card, which should be on the right of the screen:
- Click on the Activate the developer mode link
- Wait for the UI to reload
http://localhost:8069/web#menu_id=102&action=94, then you need to change this to
To exit the developer mode, you can do either of these:
- Edit the URL and remove that string
- Close your browser tab and open a new one
- Use the Deactivate the developer mode link displayed in the Share the love card when the Developer mode is active
How it works...
When in developer mode, two things happen:
- You get tooltips when hovering over a field in a form view or over a column in list view, providing technical information about the field (internal name, type, and so on)
- A drop-down menu with a Bug icon is displayed next to the user's menu in the top-right corner, giving access to technical information about the model being displayed, the various related view definitions, the workflow, custom filter management, and so on
Updating Odoo from source
In the first recipe, we saw how to install Odoo from source using the git repository. The main benefit of this setting is being able to update the source code of Odoo using git to get the latest bug fixes.
Stop any instance currently running with the Odoo source you are about to update.
Make a backup of all the databases you care about in case something goes bad. This is obviously something you need to do for production databases. Refer to the Managing Odoo server databases recipe for instructions.
Then, make a note of the current version of the source you are running. The best way is to create a lightweight tag using the following command:
$ cd ~/odoo-dev/odoo
$ git checkout 11.0
$ git tag 11.0-before-update-$(date --iso)
How to do it...
To update the source code of Odoo, use the following command:
$ git pull –-ff-only origin 11.0
This will fetch the latest version of the source code committed to the current branch.
To update an instance running on this code, run the following command:
$ ./odoo-bin -c myodoo.cfg --stop-after-init -u base
-u is the shortcut notation for the --update option of odoo-bin.
If you don't have a database set in the configuration file, you will have to add the
-d database_name option. This command is to be repeated for all of the instances running with this version of the source code.
If the update fails, don't panic, because you have backups:
- Read the error message carefully and save it to a file, as it will be useful to make a bug report later
- If you cannot figure out what the problem is, restore the service; restore the Odoo source code to the previous version, which is known to work using the tag you set before updating the source version:
$ git reset --hard 11.0-before-update-$(date --iso)
- Drop the broken databases and restore them from the backups you made (refer to the Managing Odoo server databases recipe for instructions)
- Restart your instances and tell your users that the upgrade has been postponed
How it works...
Updating the source code is done by ensuring that we are on the correct branch using git checkout, and then fetching the new revisions using git pull. The --ff-only option will cause a failure if you have local commits not present in the remote repository. If this happens and you want to keep your changes, you can use git pull (without --ff-only) to merge the remote changes with yours; otherwise, use git reset --hard origin/11.0 to force the update, discarding your local modifications.
The update command uses the following options:
- -c: Specifies the configuration file
- --stop-after-init: Stops the instance when the update is over
- -u base or --update base: Requests the update of the base module
When updating a module, Odoo does the following:
- It updates the database structure for the models defined in the module for which the structure changes. For updates on the stable branch of Odoo, there should be no such changes, but this can happen for your own addons or third party addons.
- It updates the database records stored in data files of the module, most notably the views. It then recursively updates the installed modules that have declared a dependency on the module.
Since the base module is an implicit dependency of all Odoo modules, updating it will trigger an update of all of the installed modules in your instance. To update all installed modules, the alias all can be used instead of base.
