如何RSPEC在加入記錄多到許多在軌3.1.0

Question

下面是創建RFQ控制器：

def create 
    if has_create_right? 
     @rfq = Rfq.new(params[:rfq], :as => :roles_new) 
     #save into join table rfqs_standards 
     params[:rfq][:standard_ids].each do |sid| 
     @rfq.standards << Standard.find(sid.to_i) if !sid.nil? 
     end 
    if @rfq.save 
     redirect_to URI.escape("/view_handler?index=0&msg=RFQ saved!") 
     else 
     flash.now[:error] = "RFQ not saved!" 
     render 'new' 
     end 
    end 
    end 

這裏是RSpec的代碼

describe "'create'" do 
    it "should be successful for corp head" do 
     session[:corp_head] = true 
     session[:user_id] = 1 
     s = Factory(:standard) 
     rfq = Factory.attributes_for(:rfq) 
     rfq.standards << s 
     get 'create', :rfq => rfq 
     response.should redirect_to URI.escape("/view_handler?index=0&msg=RFQ saved!") 
    end 
    end 

的錯誤是：

1) RfqsController 'create' should be successful for corp head 
    Failure/Error: rfq.standards << s 
    NoMethodError: 
     undefined method `standards' for #<Hash:0x6741570> 
    # ./spec/controllers/rfqs_controller_spec.rb:65:in `block (3 levels) in <top (requi 

什麼是測試連接記錄的正確方法？謝謝。

從你的這部分測試：

rfq = Factory.attributes_for(:rfq) 
    rfq.standards << s 

它似乎是詢價創建爲屬性哈希，而不是一個完整的模型。您可以嘗試加入standard_ids這樣的：

describe "'create'" do 
    it "should be successful for corp head" do 
    session[:corp_head] = true 
    session[:user_id] = 1 
    s = Factory(:standard) 
    rfq = Factory.attributes_for(:rfq) 
    rfq[:standard_ids] = [s.id] # attach standard_id's to mimic the POST'ed form data 
    get 'create', :rfq => rfq 
    response.should redirect_to URI.escape("/view_handler?index=0&msg=RFQ saved!") 
    end 
end 

然而，似乎可以完成這一切的使用嵌套的屬性 - 見http://api.rubyonrails.org/classes/ActiveRecord/NestedAttributes/ClassMethods.html
