第10.13章，兩個單元測試失敗，沒有解釋

Question

我看到這個問題列在getsatisfaction.com上，但不明白解決方法。

http://getsatisfaction.com/railstutorial/topics/listing_10_15_causes_user_validation_failure_running_rspec

此代碼失敗由於某種原因在users_controller_spec.rb，也許這是因爲工廠沒有既創造一個不正確的用戶和適當的用戶來模擬用戶不當訪問正確的用戶編輯頁面： （10.13）

describe "for signed-in users" do 

     before(:each) do 
     wrong_user = Factory(:user, :email => "user@example.net") 
     test_sign_in(wrong_user) 
     end 

     it "should require matching users for 'edit'" do 
     get :edit, :id => @user 
     response.should redirect_to(root_path) 
     end 

     it "should require matching users for 'update'" do 
     put :update, :id => @user, :user => {} 
     response.should redirect_to(root_path) 
     end 

我得到運行rspec的以下錯誤：

Failures: 
    1) UsersController authentication of edit/update pages for signed-in users should require matching users for 'edit' 
    Failure/Error: get :edit, :id => @user 
    No route matches {:id=>nil, :controller=>"users", :action=>"edit"} 
    # ./spec/controllers/users_controller_spec.rb:223:in `block (4 levels) in <top (required)>' 

    2) UsersController authentication of edit/update pages for signed-in users should require matching users for 'update' 
    Failure/Error: put :update, :id => @user, :user => {} 
    No route matches {:id=>nil, :user=>{}, :controller=>"users", :action=>"update"} 
    # ./spec/controllers/users_controller_spec.rb:228:in `block (4 levels) in <top (required)>' 

Answer 1

那麼，給出了的解釋：它試圖建立沒有任何id提供的路線。您確定@user包含實際用戶嗎？
