Javascript 只有在AJAX创建帖子后，才能将_链接到不匹配的路由

基本上，每次我使用AJAX创建帖子时，它都不会呈现新帖子，因为这行代码：

<%= link_to "promote", vote_scribble_path(:scribble_id => scribble.id, :vote => true), remote: true, method: :post%>

以下是正在运行的完整代码：

create.js.erb在创建后更新帖子列表

 /*Replace the html of the div post_lists with the updated new one*/
 $("#posts_list").html("<%= escape_javascript( render(:partial => "scribbles/scribbles") ) %>");

scribble\u controller.rb

def vote
  @scribble = Scribble.find(params[:scribble_id])
  @vote = params[:vote]
  if @vote == "true"
    @v = :up
    current_user.vote(@scribble, :direction => @v)
  else
    current_user.unvote_for(@scribble)
  end
    respond_to do |format|
      format.js{}
    end
end

您应该在

链接中传递
id
而不是
scribble\u id

<%= link_to "promote", vote_scribble_path(:id => scribble.id, :vote => true), remote: true, method: :post%> 

您可以通过运行
rake routes
来检查

正如您所看到的，
vote\u scribble\u path
需要一个
id
占位符，而不是
scribble\u id
，这就是为什么您会收到错误，因为Rails在应用程序中找不到与
scribbles匹配的路由，所以您的路由建议您的控制器应为
参数[：id]
，而不是
参数[：scribble\u id]
。更改
vote\u scribble\u路径（：scribble\u id=>scribble.id[…]）
为
vote\u scribble\u路径（：id=>scribble.id[…]）
哈哈哈，谢谢！！！成功了。我可以接受晚一点的答复。你回答得太快了：没问题。很乐意帮忙：）
  <% @scribbles.each do |scribble| %>
<%= link_to "promote", vote_scribble_path(:scribble_id => scribble.id, :vote => true), remote: true, method: :post%>
  <%end%>

<%= link_to "promote", vote_scribble_path()%>

vote_scribble_path(:scribble_id => scribble.id, :vote => true), remote: true, method: :post, :put,:get %> tried them all still same error 

  resources :scribbles do
        member do
      post 'vote'
    end
    end

def vote
  @scribble = Scribble.find(params[:scribble_id])
  @vote = params[:vote]
  if @vote == "true"
    @v = :up
    current_user.vote(@scribble, :direction => @v)
  else
    current_user.unvote_for(@scribble)
  end
    respond_to do |format|
      format.js{}
    end
end

<%= link_to "promote", vote_scribble_path(:id => scribble.id, :vote => true), remote: true, method: :post%> 

vote_scribble POST   /scribbles/:id/vote(.:format)        scribbles#vote
