Gettin 500內部服務器錯誤在AJAX請求上的rails

Question

我試圖從窗體創建一條記錄。我使用了railscast 136作爲基礎工作。當我嘗試提交時，我得到一個缺少部分的500錯誤。我創建了與控制器相關的javascript視圖，但它正在請求一個與模型名稱相同的視圖。

Answer 1

你的堆棧跟蹤顯示

Missing partial appointments/appointment 

所以看起來軌正試圖使部分所謂的約會/ appointments.html或約會/ appointments.js

難道一個名爲appointments.js文件。 erb或appointmentments.html.erb存在？

如果沒有，然後創建它。

但我懷疑你正在嘗試做的是展示你的約會，因爲我想你想下面的代碼更新一些元素的HTML的頁面

$('#appointments').append('<%= j render(@appointment) %>'); 

我認爲你需要這條線對紅

$('#appointments').append('<%= j render :partial => 'appointments/appointment', :formats => :html %>'); 

你的HTML視圖部分應約會/ _appointment.html.erb

Answer 2

這是因爲要渲染的局部視圖中的約會/ new.html.erb而不是在控制器創建方法。

由於局部視圖中的定義約會/ new.html.erb，所以相應的javascript 視圖應約會/ new.js.erb。
