Question

我正在编写一个控制器规范，我首先创建一个3 @users的数组。看起来像这样：

describe 'POST #create' do
    context 'when invited user IS an existing user' do
        before :each do
          @users = [
            attributes_for(:user),
            attributes_for(:user),
            attributes_for(:user)
          ]
        end

        it 'correctly finds User record of invited user' do
          login_user
          post :create, { email: @users.first[:email] }
          invited_user = User.find_by(email: controller.params[:email])
          expect(invited_user).to be_a(User)
        end
    end
end

当我使用此测试运行rspec时，它会失败并给我这个错误：

 1) Users::InvitationsController POST #create when invited user IS an existing user correctly finds User record of invited user
     Failure/Error: expect(invited_user).to be_a(User)
       expected nil to be a kind of User(id: integer, email: string, encrypted_password: string, reset_password_token: string, reset_password_sent_at: datetime, remember_created_at: datetime, sign_in_count: integer, current_sign_in_at: datetime, last_sign_in_at: datetime, current_sign_in_ip: string, last_sign_in_ip: string, created_at: datetime, updated_at: datetime, first_name: string, confirmation_token: string, confirmed_at: datetime, confirmation_sent_at: datetime, unconfirmed_email: string, invitation_relation: string, avatar: string, invitation_token: string, invitation_created_at: datetime, invitation_sent_at: datetime, invitation_accepted_at: datetime, invitation_limit: integer, invited_by_id: integer, invited_by_type: string, invitations_count: integer, bio: text, last_name: string, gender: integer)

以下是:user的工厂：

  factory :user do
    association :family_tree
    first_name { Faker::Name.first_name }
    last_name { Faker::Name.last_name }
    email { Faker::Internet.email }
    password "password123"
    password_confirmation "password123"
    bio { Faker::Lorem.paragraph }
    invitation_relation { Faker::Lorem.word }
    # required if the Devise Confirmable module is used
    confirmed_at Time.now
    gender 1
  end

我相信，正在发生的事情是User.find_by ActiveRecord查找返回nil。

但如果我在上面创建了这3个用户记录，为什么会返回nil？

为什么即使在使用FactoryGirl创建记录之后我也无法在我的测试数据库中找到记录？
