ruby-on-rails - factory_girls 序列和唯一性

Question

我在 factories.rb 中有这个设置。

Factory.sequence(:email) { |n| "email#{n}@factory.com" }
Factory.sequence(:username) { |n| "username_#{n}" }

Factory.define :user do |u|
  u.email { Factory.next :email }
  u.username { Factory.next :username }
  u.first_name 'Ivan'
  u.last_name 'Pupkin'
  u.latitude '42'
  u.longitude '-71'
  u.password 'qwerty'
  u.password_confirmation 'qwerty'
end

当我创建 Factory(:users) 的两个实例时，我遇到了唯一性错误。

describe CartsController do

  let(:user) { Factory(:user) }
  let(:another_user) { Factory(:user) }
  let(:cart) { Factory(:cart) }


  describe 'show my cart' do
    before { sign_in user}
    before { get :show, :id => user.carts.last }
    it { should respond_with :success }
  end

  describe 'show different person cart' do
    before { sign_in user }
    before { get :show, :id => another_user.carts.last}
    it { should respond_with :redirect }
  end
end

我的问题在哪里？

Failure/Error: let(:user) { Factory(:user) }
Validation failed: Username has already been taken, Email has already been taken

Answer 1

您的数据库中似乎有记录，因为 let(:user) { Factory(:user) } 而不是 let(:another_user) { Factory(:user) } 所以我看到了两种可能的解决方案:在顶部添加 User.delete_all 或手动清理 DB
