rails 4、ajax partial view return "gsub"エラー？

Question

私は私のドロップダウン選択を私のドロップダウン選択が私のドロップダウン選択を変更すると、私はスクリプトの応答で、ajax関数を起動する 私の目標は動的に "チェックボックス"と "イメージ"タグのようないくつかのHTMLを表示するdivをロードすることです私のドロップダウンで、私はこれを行う：

私のjs：

$(document).ready(function() 
    { 


      $('#apartements_select').change(function() { 



        $.ajax({ 
          url: "/units/getfloorplans", 
          data: { 
          apt_id : $('#apartements_select').val() 
          }, 
          dataType: "script" 
         }); 


      }); 

    }); 

私のコントローラ "単位/ getfloorplans"

def getfloorplans 

    floorplan = Floorplan.where(:apt_id => params[:apt_id]) 

    @imgs = floorplan 
    end 

私の元の部分のjsファイル

を

alert("wei"); 

$('#divUnitplan').append("<%= escape_javascript(@imgs.each{|i| image_tag i.floorplanphoto.thumb.url} ) %> 
         "); 

私は私の部分のjsファイルが呼ばれ、何とか私はここでエラー

を持っている

$('#divUnitplan').append("<%= escape_javascript(@imgs.each{|i| puts image_tag i.floorplanphoto.thumb.url} ) %> 
         "); 

に私のjsファイルを変更しましたが、私の最新のエラートレースです：

NoMethodError in Units#getfloorplans 

Showing C:/Users/lenovo/Documents/urbanace/urbanacecode/app/views/units/getfloorplans.js.erb where line #5 raised:
