Missing template Rails version：5.0.5

Question

我想恢復我的表單上的驗證錯誤消息（必須沒有重複的成分），但我總是有一個MISSING TEMPLATE，我不能糾正，我知道這是一個路線問題，但我不知道哪一個。 我有3種型號，雞尾酒成分和劑量，劑量鏈接雞尾酒和成分

錯誤信息

缺少模板雞尾酒/ 23含{：區域設置=> [：EN]：格式=> [：HTML]， ：變體=> []，：處理器=> [：生的，：ERB， ：html，：builder，：ruby， ：coffee，：jbuilder]}。搜查：* 「/家/ dezrt /代碼/ Pseud0/Rails的老總雞尾酒/應用/視圖」

此行render cocktail_path(@cocktail)是錯誤的原因。 render加載視圖。所以render的輸入通常應該是文件的名稱，在您的案例show視圖cocktails。將其更改爲render 'cocktails/show'應修復該錯誤。

此外，你似乎在render和redirect_to之間感到困惑。我建議你閱讀render vs redirect
