The Model Dependency diagram reflects links between the models, specified in the source code.

To show relationship links between models, follow these general steps
  1. Open for editing the desired model classes. You can do that by choosing a model class in the Rails view, or in the Model Dependency diagram, and pressing F4F4F4F4F4F4F4F12 or Ctrl+Shift+EF4⌘ Down or F4F4F3F4.
  2. In the editor, add relationship statements to the respective classes. For example:
                class Owner < ActiveRecord::Base
        attr_accessible :first_name, :last_name, :pet_name
                has_many :pets
    class Pet < ActiveRecord::Base
        attr_accessible :age, :nickname, :species, :owner
                belongs_to :owner
  3. Switch to the Model Dependency diagram, and see the relationship links between the models, with edge labels.
