                          Errata

                          - 9 submitted: last submission 14 Nov 2013

                          Errata type: Code | Page number: 30

                          Towards the bottom of the page, in the section One final step it suggests code for the hello.php view file as:

                          <?php <h1>Hello World!</h1>

                          However, the beginning PHP tag is not needed, just the html snippet:

                          <h1>Hello World!</h1>

                           

                          Errata type: Code | Page number: 37

                          Towards the top of the page, in the section Getting a little help from Yii CHtml it suggests code for the hello.php view file as:

                          CHtml::link('Goodbye'array('message/goodbye'));

                          However, a comma is missing between the 'Goodbye' and the array(). It should read:

                          CHtml::link('Goodbye', array('message/goodbye'));

                          Errata type: Typo | Page number: 53

                          Small typo close to the bottom of the page. It says:

                          Change the assertEquals(true) statement...

                          But should read

                          Change the assertTrue(true) statement...

                          Errata type: Typo | Page number: 188

                          At the bottom of the page (in the e-book), in the code declaration for adding a foreign key on the comment table, there is a missing ending quote character on the first of the two RESTRICT arguments. It is printed as "RESTRICT, but should be "RESTRICT".

                          The entire line should be: $this->addForeignKey("fk_comment_owner", "tbl_comment", "create_user_id", "tbl_user", "id", "RESTRICT", "RESTRICT");

                          Errata type: Others | Page number: 178-179

                          This is not exactly a book error, but in order for the application to allow a user to create multiple projects as well as assign the same users to multiple projects within the same role, we need to make a small change to the code when associating a user to a role upon project creation. We need wrap the role assignment in an if statement to determine whether or not the user has already been added to the RBAC hierarchy for that role.

                          if(!$auth->isAssigned($this->role, $this->_user->id))
                          {
                          $bizRule='return isset($params["project"]) && $params["project"]->allowCurrentUser("'.$this->role.'");';
                          $auth->assign($this->role,$this->_user->id, $bizRule);
                          }

                          Errata type: Others | Chapter number: 7

                          After RBAC implementation
                          This is not exactly a book error, but once we change to using our RBAC structure, we need to change our simple access rules, defined in protected/components/Controller.php to use the role rather than name when checking if the user is an admin. So in our allow rule, we need to change:
                          'users'=>array('admin'),
                          to
                          'roles'=>array('admin'),

                          This is correct in the code but was not explicit in the printed code.

                          The CActiveRecord::beforeValidate() method in the second line of the information box on the page should be:

                          CActiveRecord::afterValidate()

                          change this:

                          to this:

                          • Use Yii database migrations to version and manage your database changes
                          • Create user-based applications with Yii's authentication model
                          • Enhance your user-based application to control a user's access to feature functionality
                          • Write an administrative console application to extend the features provided by Yii's powerful command-line tools
                          • Integrate other frameworks and libraries into a Yii application to further extend its feature set
                          • Spend less time managing application configuration by taking advantage of Yii's sensible defaults and conventions.
                          • Learn how easy it is to implement a multi-user application by utilizing Yii's authentication and role-based authorization models
                          • Update your code to properly manage the user's last login time and store it in the database

                          In Detail

                          This book is a step by step tutorial in developing a real-world application using the incremental and iterative approach to software development. You learn about agile software development by leaning on the agile nature of the Yii application development framework. You touch on each aspect of the software development lifecycle by building a project task management application from concept through production deployment.

                          After a brief, general introduction to the Yii framework and outlining the software development approach taken throughout the book, the chapters break down in the same way as software development iterations do in real-world projects. After the 1st iteration, you will have a working and tested application with a valid, tested connection to a database.

                          In the 2nd and 3rd iterations, we flesh out our main database entities and domain object model and become familiar with Yii's object-relational-mapping (ORM) layer, Active Record. We also learn how to lean on Yii's auto-generation tools to automatically build our create/read/update/delete (CRUD) functionality against our newly created model. These iterations also focus on how Yii's form validation and submission model works. By the end of the third iteration you will have a working application that allows you to mange projects and issues (tasks) within those projects.

                          The 4th and 5th iterations are dedicated to user management. We learn about the built-in authentication model within Yii to assist in application login and logout functionality. We then dive into the authorization model, first taking advantage of a Yii's simple access control model, then implementing the more sophisticated role-based access control (RBAC) framework that Yii provides.

                          By the end of the 5th iteration, all of the basics of a task management application are in place. The next several iterations are focused on the nice-to-haves. We add user comment functionality, introducing a reusable content portlet architecture approach in the process. We add in an RSS Web feed and demonstrate how easy it is to integrate other third-party tools within a Yii application. We take advantage of Yii's theming structure to help streamline and design the application, and then introduce Yii's internationalization (I18N) features so the application can be adapted to various languages and regions without engineering changes.

                          Finally, we turn our focus to production deployment. We introduce ways to optimize performance and security to prepare the application for a real-world production environment.

                          Approach

                          This is a step-by-step tutorial for developing web applications using Yii. This book follows the test-first, incremental, and iterative approach to software development while developing a project task management application.

                          Who this book is for

                          If you are a PHP programmer with knowledge of object oriented programming and want to rapidly develop modern, sophisticated web applications, then this book is for you. No prior knowledge of Yii is required to read this book.
