重定向到@timecard導致'沒有路由匹配[PATCH]「/ timecards」

Question

無法找出此路由問題：我從我的更新控制器操作重定向到修改後的@timecard，並得到以下錯誤：無路由匹配[PATCH]「/ timecards」

爲什麼rails會嘗試使用PATCH重定向到timecards＃index？

這不是我如何重定向到最近編輯的@timecard？

在timecards_controller.rb：

輸出的

def edit 
    @timecard = Timecard.find(params[:id]) 
    end 

    def update 
    @timecard = Timecard.find(params[:id]) 
    @timecard.update_attributes!(timecard_params) 
    redirect_to @timecard 
    end 

耙路線：

$ rake routes 
         Prefix Verb URI Pattern             Controller#Action 
    timecard_timecard_entries GET /timecards/:timecard_id/timecard_entries(.:format)   timecard_entries#index 
          POST /timecards/:timecard_id/timecard_entries(.:format)   timecard_entries#create 
new_timecard_timecard_entry GET /timecards/:timecard_id/timecard_entries/new(.:format)  timecard_entries#new 
edit_timecard_timecard_entry GET /timecards/:timecard_id/timecard_entries/:id/edit(.:format) timecard_entries#edit 
    timecard_timecard_entry GET /timecards/:timecard_id/timecard_entries/:id(.:format)  timecard_entries#show 
          PATCH /timecards/:timecard_id/timecard_entries/:id(.:format)  timecard_entries#update 
          PUT /timecards/:timecard_id/timecard_entries/:id(.:format)  timecard_entries#update 
          DELETE /timecards/:timecard_id/timecard_entries/:id(.:format)  timecard_entries#destroy 
        timecards GET /timecards(.:format)          timecards#index 
          POST /timecards(.:format)          timecards#create 
       new_timecard GET /timecards/new(.:format)         timecards#new 
       edit_timecard GET /timecards/:id/edit(.:format)        timecards#edit 
        timecard GET /timecards/:id(.:format)         timecards#show 
          PATCH /timecards/:id(.:format)         timecards#update 
          PUT /timecards/:id(.:format)         timecards#update 
          DELETE /timecards/:id(.:format)         timecards#destroy 
         root GET /               timecards#index 

Answer 1

的問題是自然的視圖。感謝@sircapsalot指向我的日誌，這表明錯誤的路由確實被調用（從視圖中的錯誤鏈接）。

Answer 2

當你調用redirect_to你應該指定路徑..不一定對象本身。

嘗試，

def update 
    @timecard = Timecard.find(params[:id]) 
    @timecard.update_attributes!(timecard_params) 
    redirect_to timecard_path(@timecard) 
end
