ruby-on-rails - 如何使用 Factory girl 创建管理员角色？

Question

好的，所以我想测试需要管理员用户的功能，我正在尝试以管理员身份登录，但为了做到这一点，我需要有一个管理员用户

这是我的代码

  let(:user) { FactoryGirl.create(:user) }
  let(:admin_role) { FactoryGirl.create(:role) }

FactoryGirl.define do
  factory :user do
    first_name "John"
    last_name  "Doe"
    email  "john@doe.com"
  end

  factory :role do
    name "Admin"
  end
end

我如何连接它们我试过user.roles << user_role但是得到了这个错误

/Users/matt/Sites/application/spec/controllers/directory_controller_spec.rb:16:in `block (3 levels) in <top (required)>': undefined local variable or method `user' for #<Class:0x007fa550890d80> (NameError)

这是我的模型

class User < ActiveRecord::Base
    has_many :roles, :through => :role_users
    has_many :role_users
    ...

class Role < ActiveRecord::Base
    has_many :users, :through => :role_users
    has_many :role_users
    ...

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

spec/factories/user.rb

FactoryGirl.define do
  factory :user do
    first_name "John"
    last_name  "Doe"
    email "john@doe.com"
  end

  factory :admin_user, :parent => :user do
    roles { [ FactoryGirl.create(:admin_role) ] }
  end

  factory :role do
    name { "Role_#{rand(9999)}" }
  end

  factory :admin_role, :parent => :role do
    name "Admin"
  end
end
