Question

我正在尝试为视频创建新评论

视频观看

show.html.erb

   <h5>New Comment</h5>

    <%= render 'comments/form' %>

  <div class = "show-comments">
    <% if @video.comments.size > 0 %>
      <h5>Comments</h5>

      <% for comment in @video.comments %>
        <div class = "well">
        <p><%= comment.content %></p>
        <small><%= comment.updated_at %></small>
        <% if comment.user_id == current_user.id %>
            <p align="right"><%= link_to 'delete', comment, method: :delete, data: { confirm: 'Are you sure?' } %></p>
        <% end %>
        </div>
      <% end %>
  <% end %>

  </div>

评论视图中的

_form.html.erb

  <%= form_for [@video, Comment.new], remote: true do |f| %>
      <p><%= f.text_area :content, :rows => 3 %></p>
      <p><%= f.submit %></p>
    <% end %>

在comments_controller.rb中创建方法

 def create
    @video = Video.find(params[:video_id])
    @comment = Comment.new(params[:comment])

    current_user.comments << @comment
    @video.comments << @comment

    respond_to do |format|
      if @comment.save

        format.html { redirect_to @video, notice: 'Comment was successfully added.' }
        format.js

      end
    end
  end

create.js.coffee.erb 文件

new_comment = $('<p><%= @comment.content %></p>')
$(".show-comments").prepend(new_comment)

当我点击提交评论按钮时，它应该调用javascript并发布新评论，但事实并非如此。

这是一条错误消息

Failed to load resource: the server responded with a status of 500 (Internal Server Error) http://localhost:3000/videos/51adc1ae25e218d5f6000001/comments
POST http://localhost:3000/videos/51adc1ae25e218d5f6000001/comments 500 (Internal Server Error)

Answer 1

尝试将文件重命名为create.js.coffee。

它应该仍然呈现erb，尽管它没有写在文件扩展名中。

让我知道它是否对你有帮助

rails ajax controller不会调用javascript
