Factory Girl - 为什么记录不断被创造？

Question

我是工厂女孩的新手。我想做的是创建 2 个用户，它们属于一个组，通过权限模型加入。这就是我所拥有的。当我运行这个 rspec 时，它创建了 2 个以上的用户，4 个以上。为什么？谢谢

factories.rb：

require 'factory_girl'

Factory.define :user do |f|
  f.sequence(:fname) { |n| "fname#{n}" }
  f.sequence(:lname) { |n| "lname#{n}" }
  f.sequence(:email) { |n| "email#{n}@google.com" }
  f.password               "password"
  f.password_confirmation { |u| u.password }
  f.invitation_code        "xxxxxxxx"
end

Factory.define :group do |f|
  f.association :user
  f.sequence(:name) { |n| "myGroup#{n}" }
  f.sequence(:private_email) { |n| "myGroup#{n}" }
end

Factory.define :permission do |f|
  f.role_id         1
  f.user {|i| i.association(:user)}
  f.group {|i| i.association(:group)}  
  f.creator_id {|i| i.association(:user).id}
end

incoming_mails_controller_spec.rb：

describe IncomingMailsController do

  include Devise::TestHelpers

  before do
    @user = Factory.create(:user, :permissions => [Factory.create(:permission)])
    @user2 = Factory.create(:user, :permissions => [Factory.create(:permission)])  
    @group = Factory(:group)
  end


  it "should create a new IncomingMail record in the db" do
  ....
  end
....

这是因为 Factory.create(:user...) 创建了 1 个用户（您有其中两个，所以那里有两个用户）。创建两个新的 Factory.create(:permissions) 还会根据您在定义（您的关联）中设置的规则创建一个用户，因此等于 4。

如果您只想在此处创建两个用户，您可以这样做

@user = Factory.create(:user)
@user1 = Factory.create(:user)
@perm1 = Factory.create(:permission, :user => @user)
@perm2 = Factory.create(:permission, :user => @user1)
