RubyMine 7.1.2 Help

Creating Models

In this section:

Generators for creating models

RubyMine makes it possible to stub out models using the Rails generators:

  • The model generator creates a model class that defines a database table, and a migration that defines columns within the table. Besides that, a unit test and a test fixture are created.
  • The scaffold generator creates a model class that defines a database table, and a migration that defines columns within the table. Besides that, a controller, forms and the other necessary resources are created.

To create a model

  1. Do one of the following:
    • Choose New on the context menu of an editor or Project tool window, or press Alt+Insert, and then choose New - Run Rails Generator.
    • Run Rails generator: choose Tools | Run Rails Generator, or press Ctrl+Alt+G.
    • With a Model Dependency diagram having the focus, choose New - Model on the context menu of the diagram background, or press Alt+Insert.
  2. In the dialog box that opens, start typing the generator name, for example, model or scaffold.
    rm_create_model

    Note that for creating models in diagram, only model generator is used.

  3. Type the name of a model to be created, in singular, and the list of fields and their types. Note that code completion is available for the field types.
    rm_create_model_fields

    A migration is created.

  4. Create columns in the table. To do that, you have to run the migration in one of the following ways:
    • Run migration as a script with the temporary run configuration. Click the migration hyperlink in the console to open the migration file in the editor:
      ruby_createModelConsole

      Then press Ctrl+Shift+F10. In this case the current migration runs in the development environment, or in the one defined in the environment.rb file.

    • Run migration as a Rake task. For example, you can press Ctrl+Alt+R, and start typing mig. Then select db:migrate from the suggestion list.

      In the Execute db:migrate dialog box, select the desired migration, and the environment that defines the database to which the migration will be applied:

      ruby_runMigration

    Once a model is created, you can view all the fields declared in this model, in the Rails view, and navigate from these table column to the corresponding methods.
