Question

I am trying to do this, in spec/models/user_role.spec:

role_trainer = FactoryGirl.create(:role_trainer)
user_role = FactoryGirl.build(:user_role, :role => role_trainer)

where I want to specify the specific "role_trainer" in spec/factories/roles.rb:

factory :role_trainer, parent: :role do |f|
  f.name "trainer"
end

and then for spec/factories/role_spec.rb, I have:

FactoryGirl.define do
  factory :user_role do
    user
    role
  end
end

and the models are:

class Role < ActiveRecord::Base
  has_many :user_roles, :dependent => :destroy
  has_many :users, :through => :user_roles

class UserRole < ActiveRecord::Base
  belongs_to :user
  belongs_to :role

That is, in words, I want to determine the "role" of the "user role" that is going to be created. However, when I do this, I do not find that the "role_trainer" was used as the role, for the user_role. (Instead, a user_role gets created by the build statement (at the top) which has nothing to do with "trainer".) What is wrong with my setup?

Another way to ask it - I need to add multiple roles to a single user, by creating multiple user_roles. How can I specify the input user, to the FactoryGirl build?

Answer 1

I would do something like this:

FactoryGirl.define do
    factory :role_trainer do
        name 'Trainer'
    end
end

That should do the trick.
