如何使用鏈接到軌道中的遠程工作在ajax 3.2

有一個簡單的資產顯示頁面，它具有部分「_assign_group」中的「建議組」鏈接。當我點擊這個遠程鏈接正確的行動被調用，但卡住了錯誤。如何使用鏈接到軌道中的遠程工作在ajax 3.2

_assign_group.html.erb

<% if @asset.has_suggested_group(@group)%> 
    Already suggested to <%= @group.name %> 
<% else %> 
    <%= link_to "Suggest to #{@group.name}", add_asset_group_path(:asset_id => @asset.id, :group_id => @group.id), :remote => true %> 
<% end %>

asset_controller.rb

class AssetsController < ApplicationController 

    def show 
     @asset = Asset.find_by_id(params[:id]) 
     @group = Group.find_by_id(params[:group_id]) 
     respond_to do |format| 
     format.html # show.html.erb 
     format.json { render json: @asset } 
     end 
    end 



    def add_group 
     @asset_group = AssetGroup.new(params[:asset_group]) 
     respond_to do |format| 
      if @asset_group.save 
    #  format.html { redirect_to asset_path(params[:asset_group][:asset_id]), notice: 'Asset added to this group.' } 
      format.js { render add_group.js } 
      else 
    #  format.html { redirect_to asset_path(params[:asset_group][:asset_id]), notice: "Asset is already added to #{@asset_group.group.name}" } 
      format.js { render add_group.js } 
      end 
     end 
     end 
    end

add_group.js.erb

$("#assign_group_to_asset").html("<%= escape_javascript(render(:partial => "assign_group")) %>");

的routes.rb

resources assets 
resources groups 
post 'assets/add_group' => "assets#add_group", :as => :add_asset_group

是error.log

在日誌「show.html.erb」得到呈現，而不是局部的「assign_group」。有什麼建議麼？

看起來像你的路由問題。你能發佈你的'routes.rb'內容嗎？ –

只是添加了路線代碼 – chaitanya

嘗試在你的routes.rb

resources assets do 
    post :add_group, :on => :member 
end

下，改變你的形式使用：

add_group_assets_path(@asset.id, :group_id => @group.id)
