我正在尝试从表单创建记录。我使用 railscast 136 作为基础工作。当我尝试提交时，由于缺少部分而收到 500 错误。我已经创建了控制器相关的 javascript 视图，但它正在请求与模型同名的视图。

错误信息

渲染的约会/create.js.erb (3.8ms) 在 12ms 内完成了 500 内部服务器错误

ActionView::Template::Error（缺少部分约会/约会与 {:locale=>[:en], :formats=>[:js, :html], :handlers=>[:erb, :builder, :coffee] }. 搜索：* "/Users/gjores/Sites/Rails/verkstad_test/app/views" ): 1: $('#appointments').append('<%= j render(@appointment) %>') ; app/views/appointments/create.js.erb:1:in _app_views_appointments_create_js_erb___2325925946390315228_70273089113920' app/controllers/appointments_controller.rb:16:increate'

控制器

 def create
    @appointment = Appointment.new(params[:appointment])
    if @appointment.save
      respond_to do |format|
        format.html { redirect_to new_appointment_path, :notice => "Successfully created appointment." }
        format.js
      end
    else
      render :action => 'new'
    end
  end

约会/new.html.erb

<div id="appointments">
    <%= render 'shared/appointment_part' %>
</div>
<% title "New Appointment" %>
<table>
<% @students.each do |s| %>
<%= form_for @appointment,  :remote => true do |f|%>
  <%= f.error_messages %>

    <%= f.hidden_field :student_id, :value => s.id %>

  <td><%= f.submit %></td>
  </tr>
<% end %>

</table>

<p><%= link_to "Back to List", appointments_path %></p>

约会/create.js.erb

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

您的堆栈跟踪显示

Missing partial appointments/appointment

所以看起来 Rails 正在尝试渲染一个名为约会/appointments.html 或约会/appointments.js 的部分

是否存在名为约会.js.erb 或约会.html.erb 的文件？

如果没有，则创建它。

但是，我怀疑您要做的是显示您的约会，因为我认为您希望下面的代码更新页面上某些元素的 html

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

我想你需要这条线变红

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

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

这是因为您在视图约会/new.html.erb中呈现部分，而不是在控制器创建方法中。

由于部分是在视图约会/new.html.erb 中定义的，所以对应的javascript 视图应该是约会/new.js.erb。
