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.
- Do one of the following:
- Choose Alt+InsertAlt+Insert, and then choose . on the context menu of an editor or Project tool window, or press
- Run Rails generator: choose Ctrl+Alt+GAlt G. , or press
- 4.5+With a Model Dependency diagram having the focus, choose on the context menu of the diagram background, or press Alt+InsertAlt+Insert.
- In the dialog box that opens, start typing the generator name, for example, model or scaffold.
Note that for creating models in diagram, only model generator is used.
- 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.
A migration is created.
- 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:
Then press Ctrl+Shift+F10Ctrl+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+RAlt 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:
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.
- 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:
A model can be created without fields. In this case, the corresponding table in the target database will contain no columns. You can add fields later using migrations.
