Link_to remote =>真正导致奇怪的路由问题，Rails 3 [英] Link_to remote => true causing strange routing problems, Rails 3

问题描述

我在使用 link_to 远程向另一个控制器发送帖子时遇到了一些问题...结果与我预期的不太一样......

I am having some problems with link_to remote sending a post to another controller... The result are not quite what I expect..

我在 node_content.html.erb 中有这个:

I have this in node_content.html.erb:

<% @node.videos.each do |vid| %>
 <div id="vid_vid"><%= link_to image_tag("http://img.youtube.com/vi/#{vid.content}/1.jpg"),  :controller => 'videos', :action => "iframize", :video_id => vid.id,  :method => :post,  :remote => true %></div>

 <% end %>

我在videos_controller中有这个:

And I have this in videos_controller:

  def iframize
   @video = Video.find(params[:video_id])
   respond_to do |format|
     format.js
   end
 end

这在路由中:

 resource :videos do
  collection do
   post 'iframize'
  end
end

问题是当我点击链接时，它把我带到

Problem is that when I click the link, it takes me to

http://localhost:3000/videos/iframize?method=post&video_id=20

我得到

Couldn't find Video with id=iframize

我看了几十个不同的例子，他们似乎推荐了上面的，但它不起作用..我做错了什么?

I looked through tens of various examples and they seem to recommend the above, but it does not work.. What am I doing wrong?

非常感谢任何输入！

谢谢！

我尝试了这种方法 jquery 函数，它有点工作(当然仅适用于循环中的第一个视频):

I tried this approach jquery function and it kinda worked (only for the first video in the loop of course):

<% @node.videos.each do |vid| %>
  <%=  image_tag("http://img.youtube.com/vi/#{vid.content}/1.jpg", :id  => 'img_div') %>
<div id="vid_vid"> <%= vid.id %></div>
<% end %>



$('#img_div').on({
  'click': function() {
   var vid_id = document.getElementById("vid_vid").innerHTML;
   $.post("/videos/iframize/", {video_id: vid_id}); 
  }
 });

推荐答案

需要区分url选项，html选项，所以使用

You need to differentiate the url options, html options.so use

<%= link_to image_tag("http://img.youtube.com/vi/#{vid.content}/1.jpg"), 
{ :controller => 'videos', :action => "iframize", :video_id => vid.id },
{ :method => :post,  :remote => true} %>
