FactoryGirl AutoCorrect Association Error

Question

I am trying to create a has_many: has_many relationship with a factory girl.

Here are my models:

class User < ActiveRecord::Base
    has_many :user_roles
    has_many :roles, through: :user_roles
end

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

class Role < ActiveRecord::Base
    has_many :user_roles
    has_many :users, through: :user_roles
end

Here is the factory for my user:

FactoryGirl.define do
    factory :user do
        user_name { Faker::Name.user_name }

        trait :admin do
            association :user, factory: :admin, strategy: :create
        end
    end
end

Here is the factory for the admin role:

FactoryGirl.define do
    factory :admin, class: Role do
        name 'admin'
    end
end

The essence of this question:

trait :admin do
    association :user, factory: :admin, strategy: :create
end

I run it like this:

FactoryGirl.create: user ,: admin

But it gives me:

FactoryGirl::AssociationDefinitionError: Self-referencing association 'user' in 'admin'

Why is this? And how can I make this user an administrator? Should I create a user_rolefactory and create this?

Answer 1

You probably don't like the fact that you have both a custom attribute :adminand a factory called adminfor another class.

factory :admin_role, ,

Answer 2

"" FactoryGirl . - , "association_with_same_name"

factory (, trait: admin_user)
