Creating Relationship Links Between Models
The Model Dependency diagram reflects links between the models, specified in the source code.
To show relationship links between models, follow these general steps
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 F4.
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 end ... class Pet < ActiveRecord::Base attr_accessible :age, :nickname, :species, :owner belongs_to :owner end
Switch to the Model Dependency diagram, and see the relationship links between the models, with edge labels.
