Rails：工厂女孩无法顺序

刚开始工厂女孩，我遇到了排序问题：具体来说，它不增加。我试着改变数据库类型，从factory_girl 1.3.2更新到2.0.0.beta1（和从1.0到1.1.0.beta1 factory_girl_rails），尝试重新创建数据库，但同样的问题 - 序列不会增加和我在第一次插入唯一字段后出现验证错误。Rails：工厂女孩无法顺序

任何帮助非常感谢。下面的代码&跟踪堆栈：

/spec/models/user.rb

require 'spec_helper' 

describe User do describe "test user factory is correct" do 
    user = Factory(:user) 

    it "should have an email ending in example.com" do 
     #user.email.should match "[email protected]" 
    end 

    it "should have a password of foobar" do 
     user.password.should == 'foobar' 
    end 

    it "should have a password confirmation field of foobar" do 
     user.password_confirmation.should == 'foobar' 
    end 
    end 

end

/spec/factories/user.rb

Factory.define :user do |f| 
    f.sequence(:email) { |n| puts "Email ##{n}"; "factory_#{n}@example.com" } 
    f.password 'foobar' 
    f.password_confirmation { |p| p.password } 
end

为什么你有这样的块中的两个语句？ f.sequence（：email）{| n |放入“Email ## {n}”; “factory_#{n}@example.com”} – 2010-12-20 19:29:45

你运行过'tail -f log/test.log'吗？ – 2010-12-20 19:31:18

你使用自动测试？另外，你使用什么数据库清理策略来清理运行之间的测试数据库？ – 2010-12-20 21:53:17

你的问题不是与工厂的女孩。在实例化“用户”时，您需要从before块中执行此操作，以便为每个正在运行的测试创建一个新用户。用户变量也应该是一个实例变量（即前缀为@）

require 'spec_helper' 

describe User do 

    describe "test user factory is correct" do 

    before(:each) do 
     @user = Factory(:user) 
    end 

    it "should have an email ending in example.com" do 
     @user.email.should match "[email protected]" 
    end 

    it "should have a password of foobar" do 
     @user.password.should == 'foobar' 
    end 

    it "should have a password confirmation field of foobar" do 
     @user.password_confirmation.should == 'foobar' 
    end 

    end 

end

有你分别定义了序列？下面是我厂文件中的一个摘录：

Factory.sequence(:email)  {|n| "person#{n}@example.com" } 

Factory.define :user do |f| 
    f.name     "John Doe" 
    f.email     { Factory.next :email } 
end

（我知道FG支持在工厂内嵌入定义序列，但很高兴看到你的问题是特定于内联语法，还是适用于使用旧语法定义的序列。） – 2010-12-20 23:15:25

我不知道为什么会发生，但这里有几个建议：

获取未保存在数据库中的用户：

用户= Factory.build（：用户）

或者，

使用每个块之前：

之前（：每个）做 @user =厂（：用户）端

（然后将 “用户” 的变量 “@user” ）

随着latest syntax：

FactoryGirl.define do 

    sequence :email { |n| "test#{n}@email.com" } 

    factory :user do 
    name   "John Doe" 
    email   { FactoryGirl.generate(:email) } 
    end 

end
