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.
