如何在rails控制器中格式化json？通过link_to我发送并进入方法params [：cat]，然后我通过父（params [：cat]）获取所有孩子，但是如何为我的jqTree以json格式格式化这一切？所以它看起来像 {label : (here go params[:cat]), children: [{all @search_trees.id}]} ？

require 'json'
        @search_trees = SearchTree.find(:all, :include => [:designation], :conditions => { :STR_ID_PARENT => params[:cat]})
        #data = "{ label : '10001',  children : [{label : '10111'},{label : '10122'}]  }"
        respond_to do |format|
          format.html # index.html.erb
          format.xml  { render :xml => @search_trees }
          format.json { render :json => data }
        end

我将从这里的长问题中提取一部分问题：

如何在 Rails 应用程序中正确执行 jquery 树？

她是我的json：

[{"search_tree":{"STR_DES_ID":42275,"STR_ID":10130,"STR_ID_PARENT":10726,"STR_LEVEL":4,"STR_NODE_NR":130,"STR_SORT":621,"STR_TYPE":1," designation_id":42275}},{"search_tree":{"STR_DES_ID":42277,"STR_ID":10132,"STR_ID_PARENT":10726,"STR_LEVEL":4,"STR_NODE_NR":132,"STR_SORT":620," STR_TYPE":1,"designation_id":42277}},{"search_tree":{"STR_DES_ID":43152,"STR_ID":10730,"STR_ID_PARENT":10726,"STR_LEVEL":4,"STR_NODE_NR":730," STR_SORT":622,"STR_TYPE":1,"designation_id":43152}},{"search_tree":{"STR_DES_ID":42209,"STR_ID":12344,"STR_ID_PARENT": 10726,"STR_LEVEL":4,"STR_NODE_NR":2344,"STR_SORT":623,"STR_TYPE":1,"designation_id":42209}}] 我需要像这样输出jqTree - 从 json 创建树数据

If you want to customize your json, you can use RABL or JBuilder. You will find screencasts here : http://railscasts.com/episodes/320-jbuilder?autoplay=true and here : http://railscasts.com/episodes/322-rabl?autoplay=true.
