有一个简单的资产展示页面，在部分“_assign_group”中有“建议分组”链接。当我单击此远程链接时，正确的操作被调用但卡在错误中。

_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 %>

资产控制器.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")) %>");

路线.rb

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

在日志中“show.html.erb”被渲染而不是部分“assign_group”。有什么建议么？

在你的尝试以下routes.rb

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

并更改您的表格以使用：

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