Factory Girl怎么没有对独特属性进行排序？
我的控制器规范失败，因为Factory Girl似乎正在创建非唯一用户，即使我对需要唯一的用户属性进行排序。
错误
1) TopicsController POST #create when topic is invalid should render new Failure/Error: let(:invalid_topic) {Factory.build :invalid_topic} ActiveRecord::RecordInvalid:Validation failed: Email has already been taken, Username has already been taken 2) TopicsController POST #create when topic is valid should redirect to show Failure/Error: let(:valid_topic) {Factory.build :topic} ActiveRecord::RecordInvalid: Validation failed: Email has already been taken, Username has already been taken 控制器规格（RSpec）
describe "POST #create" do let(:valid_topic) {Factory.build :topic} let(:invalid_topic) {Factory.build :invalid_topic} context "when topic is invalid" do it "should render new" do post :create, :topic => invalid_topic response.should render_template(:new) end end context "when topic is valid" do it "should redirect to show" do post :create, :topic => valid_topic response.should redirect_to(topic_path(assigns(:topic))) end end end
工厂
Factory.define :user do |f| f.sequence(:username) { |n| "foo#{n}"} f.password "password" f.password_confirmation { |u| u.password} f.sequence(:email) { |n| "foo#{n}@example.com"} end Factory.define :topic do |f| f.name "test topic" f.association :creator, :factory => :user f.forum_id 1 end
当我使用Factory.create :topic时，为什么Factory Girl不对用户属性进行排序？
rake db:test:prepare似乎解决了问题。
不过不确定原因。 架构尚未更改。
请考虑使用database_cleaner gem。 其中一个专门用于实现在测试运行之间清理数据库的目的。
这篇文章几乎解释了一切。
您应该考虑在测试结束时手动删除所有主题。 当然，它不是头号解决方案，但对我来说真的很棒。
after(:all) { Topic.delete_all }
