The addressable gem adds some nice features over Ruby's built-in URI class, but it doesn't have any helpers for extracting subdomains. In this lesson, we'll add some methods to Addressable to make accessing subdomains easier.
Did you know serialize can be used for more than saving Ruby hashes as JSON or Yaml in your db? You can take any attribute and convert it to an object seamlessly with Rails using serialize and custom coders.
ActiveRecord Aggregations let you use composed_of to combine columns into a single attribute using a Ruby object.
You might not realize your code has concepts that need to be extracted. Sometimes it's as simple as a small decorator around a Ruby class as we'll see in this lesson.
