如何從db中使用jquery正確獲取django模型？

Question

我想從django獲取模型，但沒有顯示出來。該應用程序部署在Google App Engine上。

這是錯誤，我看到：

AttributeError at /get_companies_json 

'str' object has no attribute 'status_code' 

Request Method:  GET 
Request URL: http://127.0.0.1:8000/get_companies_json 
Django Version:  1.3 
Exception Type:  AttributeError 
Exception Value:  

'str' object has no attribute 'status_code' 

下面是我的網址，查看功能：

網址：

('^get_companies_json$', 'companies.views.all_companies_json') 

觀點功能：

def all_companies_json(request): 
    # json_serializer = serializers.get_serializer("json")(); 
    companies_json = serializers.serialize("json", Company.objects.filter(approved = True)); 
    return companies_json; 

的jQuery ：

$.getJSON("/get_companies_json", 
      function(data){ 
       $.each(data.items, function(i, item){ 
        console.log(item); 
       });    
      } 
     );  

我下面jQuery的網站的例子：http://api.jquery.com/jQuery.getJSON/

我在做什麼錯？

我認爲這個功能

def all_companies_json(request): 
    # json_serializer = serializers.get_serializer("json")(); 
    companies_json = serializers.serialize("json", Company.objects.filter(approved = True)); 
    return companies_json; 

需要改變，以

def all_companies_json(request): 
    # json_serializer = serializers.get_serializer("json")(); 
    companies_json = serializers.serialize("json", Company.objects.filter(approved = True)); 
    return HttpResponse(companies_json, mimetype="application/json")
