沒有這樣的屬性：屬性ID類：grails.converters.JSON

我有這樣一個Grails控制器動作.....沒有這樣的屬性：屬性ID類：grails.converters.JSON

控制器：Home.groovy

def search(){ 

     def pl=Long.valueOf(params.pl).longValue(); println pl 

     def mil=Long.valueOf(params.mil).longValue(); println mil 
     def mal=Long.valueOf(params.mal).longValue(); println mal 

     def mic=Long.valueOf(params.mic).longValue(); println mic 

     def mac=Long.valueOf(params.mac).longValue(); println mac 


     def mib=Long.valueOf(params.mib).longValue(); println mib 
     def mab=Long.valueOf(params.mab).longValue(); println mab 


     Type pt=Type.valueOf(params.pt); println pt 

      def results=Project.executeQuery(""" 
       select new map (prt.name as name,pp.id as propertyId,pp.constructedSize as constructedSize, 
       prt.propertyLocation.name as location,pp.mrp as mrp,pp.landSize as landSize, 
        pp.propertyType.name as propertyType) 
         from Project prt 
         JOIN prt.projectProperties pp where 
          pp.propertyType.name=:pt and 
           pp.constructedSize between :mic and :mac and 
           pp.landSize between :mil and :mal and 
            pp.mrp between :mib and :mab and 
             prt.propertyLocation.id=:pl  
         """,[mic:mic,mac:mac,mil:mil,mal:mal,mib:mib,mab:mab,pl:pl,pt:pt]) 
     println results 

     def customerInstance=new Customer() 
     render (view:'search',model:[results:results as JSON,customerInstance:customerInstance]) 
    }

和從此操作呈現的視圖僅在以下部分出現錯誤...

查看：Search.gsp

<table style="width: 50%;"> 
     <g:each in="${results}" var="item"> 
      <tr> 
       <td><div class="box shadow-outside-all" > 
        <input type="checkbox" name="getInterest" id="getInterest" 
        value="${item.propertyId}" style="float: left;" /> 
        <b> ${item.name?.encodeAsHTML()}</b></br> 
        Property Type: ${item.propertyType?.encodeAsHTML()}</br> 
        Constructed Size:${item.constructedSize?.encodeAsHTML()}</br> 
        Land Size: ${item.landSize?.encodeAsHTML()}</br> 
        MRP: ${item.mrp?.encodeAsHTML()}</br> 
        Location: ${item.location?.encodeAsHTML()}</br> 
        </div> 
       </td> 
      </tr> 
     </g:each> 
     <br /> 

    </table>

，誤差...

錯誤

任何幫助，將不勝感激.....

你爲什麼你的渲染結果JSON這樣呢？不要將它們呈現爲JSON。您的GSP期望地圖/模型不是JSON結果。 –

thinks @JoshuaMoore你的主意工作 –

爲什麼@Dónal我知道也許它是一個愚蠢的問題，但我是一個初學者很抱歉 –

你爲什麼渲染你結果就像那樣的JSON？不要將它們呈現爲JSON。您的GSP期望地圖/模型不是JSON結果。

從你的控制器使您的結果是這樣，而不是：

render(view:'search', model:[ 
    results:results, 
    customerInstance:customerInstance 
])
