AttributeError的： '快譯通' 對象有沒有屬性 '_meta'

Question

了代碼

shops = Shop.objects.filter(id__in=list(set(shop_ids))).all() 
shop_list = [] 
for s in shops.only(): 
    shop_list.append({ 
     'id': s.id, 
     'name': s.name, 
     'preview': s.preview, 
    }) 

response_data['shop'] = serializers.serialize('json', shop_list) 

return response_data 

.....

AttributeError: dict object has no attribute _meta 

我怎樣才能解決這個問題？

Answer 1

序列化期望queryset作爲第二個參數 - 並且您正在傳遞字典列表; docstring：

def serialize(format, queryset, **options): 
    """ 
    Serialize a queryset (or any iterator that returns database objects) using 
    a certain serializer. 
    """ 
    ... 

基本上，您的數據幾乎是序列化的。請撥打簡單json.dumps();

快樂編碼。
