Question

我正在尝试从表单创建记录。我使用railscast 136作为地面工作。当我尝试提交时，我因缺少部分而得到500错误。我已经创建了控制器相关的javascript视图，但它正在请求一个与模型同名的视图。

错误消息

呈现约会/ create.js.erb（3.8ms）已完成500内部   服务器错误12毫秒

控制器

 def create
    @appointment = Appointment.new(params[:appointment])
    if @appointment.save
      respond_to do |format|

Answer 1

您的堆栈跟踪显示

Missing partial appointments/appointment

所以看起来rails试图呈现部分名为appointmentments / appointmentments.html或约会/约会.js

是否存在名为appointmentments.js.erb或appointmentments.html.erb的文件？

如果没有，则创建它。

我怀疑你要做的是显示你的约会，因为我认为你想要下面的代码来更新页面上某些元素的html

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

我认为你需要这一行为红色

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

你的html视图部分应该是约会/ _appointment.html.erb

Answer 2

这是因为您在视图 appointmentments / new.html.erb 中渲染部分而不在控制器创建方法中渲染。

由于部分是在视图 appointmentments / new.html.erb 中定义的，因此相应的 javascript视图应为约会/ new.js.erb
