  3. Artist.where("name = 'Defeater'") <- To search for a specific record. Returns a list of results, even if there's only one.

Creating a new route, controller and haml view

• Creating the route: Modifying the /config/routes.rb file: Example:

  1. root 'pages#show
  2. root is the subdirectory to follow
  3. pages is the controller
  4. show is the action to perform

• Creating a new controller for the route Running the following command will give us a new controller and .erb files for our route:

  1. rails generate controller pages new create update edit destroy index show
  2. rails generate controller should stay unmodified
  3. pages is the route name to create the controller for
  4. new specifies that we want to create a new controller
  5. create update edit destroy index show are the actions our controller will have

• Converting default controller generated .erb to .haml files

  1. Run the following rake command rake haml:erb2haml
  2. Enter 'y' when prompted to remove the .erb files
