Rspec的越来越“堆栈层次过深，”从协会

Question

对于控制器测试，在我定义的模型规范的顶部：

let(:user) { Factory(:user, :company => company) } 
    let(:facility) { Factory(:facility, :company => company) } 
    let(:company) { Factory(:company, :facilities => [facility]) } 

，并做基本指标规格：

context "responding to GET index" do 
    it "should expose all facilities as @facilities" do 
     user.company.should_receive(:facilities).and_return([facility]) 
     get :index 
     assigns[:facilities].should == [facility] 
    end 
    end 

但我发现了这个错误：

should expose all facilities as @facilities 
stack level too deep 
/Users/dmix/.rvm/gems/ruby-1.9.3-p0/gems/rspec-core-2.6.4/lib/rspec/core/let.rb:90 
88  module InstanceMethods 
89  def __memoized # :nodoc: 
90   @__memoized ||= {} 
91  end 
92  end 

这个问题似乎在同一时间被引用的3家工厂。

如果我删除：从公司工厂定义设施，堆栈错误去的方式：

let(:company) { Factory(:company) } 

我怎么厂三个型号，所有没有得到一个计算器相互引用？

Answer 1

问题是您的facility和company对象互相引用。我认为您的company工厂的:facilities => [facility]部分可能是不必要的，因为您已指定facility对象的公司为company。试试这个：

let(:facility) { Factory(:facility, :company => company) } 
let(:company) { Factory(:company) }
