Usage:
  rails generate model NAME [field[:type][:index] field[:type][:index]] [options]

Options:
      [--skip-namespace]  # Skip namespace (affects only isolated applications)
  -o, --orm=NAME          # Orm to be invoked
                          # Default: active_record

ActiveRecord options:
      [--migration]            # Indicates when to generate migration
                               # Default: true
      [--timestamps]           # Indicates when to generate timestamps
                               # Default: true
      [--parent=PARENT]        # The parent class for the generated model
      [--indexes]              # Add indexes for references and belongs_to columns
                               # Default: true
  -t, [--test-framework=NAME]  # Test framework to be invoked
                               # Default: rspec

Rspec options:
  [--fixture]                   # Indicates when to generate fixture
  [--fixture-replacement=NAME]  # Fixture replacement to be invoked
                                # Default: factory_girl

Runtime options:
  -f, [--force]    # Overwrite files that already exist

  -q, [--quiet]    # Suppress status output
  -s, [--skip]     # Skip files that already exist

Description:
    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 field: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'.

    You don't have to think up every attribute up front, but it helps to
    sketch out a few so you can start working with the model immediately.

    This generator invokes your configured ORM and test framework, which
    defaults to ActiveRecord and TestUnit.

    Finally, if --parent option is given, it's used as superclass of the
    created model. This allows you create Single Table Inheritance models.

    If you pass a namespaced model name (e.g. admin/account or Admin::Account)
    then the generator will create a module with a table_name_prefix method
    to prefix the model's table name with the module name (e.g. admin_account)

Available field types:

    Just after the field name you can specify a type like text or boolean.
    It will generate the column with the associated SQL type. For instance:

        `rails generate model post title:string body:text`

    will generate a title column with a varchar type and a body column with a text
    type. You can use the following types:

        integer
        primary_key
        decimal
        float
        boolean
        binary
        string
        text
        date
        time
        datetime
        timestamp

    You can also consider `references` as a kind of type. For instance, if you run:

        `rails generate model photo title:string album:references`

    It will generate an album_id column. You should generate this kind of fields when
    you will use a `belongs_to` association for instance. `references` also support
    the polymorphism, you could enable the polymorphism like this:

        `rails generate model product supplier:references{polymorphic}`

    For integer, string, text and binary fields an integer in curly braces will
    be set as the limit:

        `rails generate model user pseudo:string{30}`

    For decimal two integers separated by a comma in curly braces will be used
    for precision and scale:

        `rails generate model product price:decimal{10,2}`

    You can add a `:uniq` or `:index` suffix for unique or standard indexes
    respectively:

        `rails generate model user pseudo:string:uniq`
        `rails generate model user pseudo:string:index`

    You can combine any single curly brace option with the index options:

        `rails generate model user username:string{30}:uniq`
        `rails generate model product supplier:references{polymorphic}:index`


Examples:
    `rails generate model account`

        For ActiveRecord and TestUnit it creates:

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

    `rails generate model admin/account`

        For ActiveRecord and TestUnit it creates:

            Module:     app/models/admin.rb
            Model:      app/models/admin/account.rb
            Test:       test/models/admin/account_test.rb
            Fixtures:   test/fixtures/admin/accounts.yml
            Migration:  db/migrate/XXX_create_admin_accounts.rb
