cheat sheets.

rails generate model


Stubs out a new model. Pass the model name, either CamelCased or under_scored,
and an optional list of attribute pairs as arguments.

Attribute pairs are column_name:sql_type arguments specifying the model's
attributes. Timestamps are added by default, so you don't have to specify them
by hand as created_at:datetime updated_at:datetime.

This generates a model class in app/models, a unit test in test/unit, a test
fixture in test/fixtures/singular_name.yml, and a migration in db/migrate.


Examples:

  rails generate model account

    creates an Account model, test, fixture, and migration:

      Model:      app/models/account.rb
      Test:       test/unit/account_test.rb
      Fixtures:   test/fixtures/accounts.yml
      Migration:  db/migrate/XXX_add_accounts.rb


  rails generate model post title:string body:text published:boolean

    creates a Post model with a string title, text body, and published flag.
