Ryan Baldwin

Ryan Baldwin is a theatre major turned computer science geek. Hailing from the prairies of Western Canada, Ryan has been developing software on a wide array of platforms and technologies since 2001. Once, he wrote a crazy system application that compiled XSD Schema Docs into XAML forms that performed two-way binding with underlying XML documents in .NET WPF. Why? Because it had to be done. Another time, he worked on a project that would mash multiple social networks together, allowing users to find out who they were indirectly "connected" to (something akin to 6 Degrees of Kevin Bacon). It was eventually shelved. In 2012, he relocated to Toronto, where he works with the University Health Network, developing systems and tools that facilitate patient information exchange. You can often find him wearing headphones and jittering in coffee shops.

Creating the catalog


At this point, we want to lay the foundation of allowing our user to catalog and view their record collection. We will create a simple Recently Added album page, and a simple Show me all the albums for this artist page (which I'll just call "the artist page"). The first thing to do in order to facilitate this incredible functionality is to create the artists table and the albums table.

Creating the artists table

We will use Migratus to create the artists table. As such, we need to create another SQL migration file. So let's do the following:

  1. In the src/migrations folder, create a new migration script called 00000000000200-artists.up.sql.

  2. For our hipstr app, the artists table is going to be extremely simple. We'll have an artist_id that uniquely identifies the artist, a name (go figure), and two timestamps, created_at and updated_at, for keeping track of when the artist was created and last updated. Add the following SQL:

    CREATE TABLE artists                              ...
