Question

我已经创建了一个show.html.erb，其中有一个复选框列表，我希望当一个复选框被cliked一个名为Generate的动作执行，然后在show.html.erb中渲染一个部分我尝试使用Action电缆但无法这样做这是我的Show.html.erb

<%= @files.each do |key,value|%>
 <div class="subdir">
 <%= check_box_tag(key, value, false, data: {remote: true, method: :post, url: generate_repository_path }) %>
 <%= label_tag key%>
 </div>
<br>
<%end%>

生成方法

  def generate
        request.POST.each do |key,value|
          @filename=key
          @path= value
        end
        @id=params[:id]
        @file=Hash.new
        if File.directory?(@path)
           Dir.chdir("#{@path}")
           Dir.glob("*").each do |entries|
             @file[entries]="#{@path}/entries"
            puts "#{entries}"
          end
          render(partial: 'operations/dir',object: @file)
          else
            puts "It is a file"
          end
      end

这是我的部分

<%= @file.each do |key,value|%>
 <%= check_box_tag(key, value, false, data: {remote: true, method: :post, class: "checkbox", url: generate_repository_path }) %>
 <%= label_tag key%>
<br>
<%end%>

这是我的operations.coffee文件

App.operations = App.cable.subscriptions.create "OperationsChannel",
  connected: ->
    # Called when the subscription is ready for use on the server

  disconnected: ->
    # Called when the subscription has been terminated by the server

  received: (data) ->
    # Called when there's incoming data on the websocket for this channel
    $(".subdir").prepend(data);

和Operations_channel.erb

class OperationsChannel < ApplicationCable::Channel
  def subscribed
    stream_from "operations"
  end

  def unsubscribed
    # Any cleanup needed when channel is unsubscribed
  end
end

这里是日志

我可以从复选框中调用方法generate而且渲染部分_dir.html.erb但是它在show.html.erb中没有更改或渲染。

Answer 1

服务器端的复选框点击处理程序应该触发ActionCable广播：http://api.rubyonrails.org/classes/ActionCable/Server/Broadcasting.html

我还建议使用操作频道文件“operations.coffee”上的已连接和已接收方法调试一些控制台日志
