我有以下用于序列化查询集的代码:
def get_shop_categories(request):
if request.method == 'POST':
parent_id = int(request.POST.get('parent_id'))
categories = (ShopCategory.objects.filter(enabled=True, parent=parent_id).values('id', 'title'))
json_posts = json.dumps(categories)
return HttpResponse(
json_posts,
content_type="application/json"
)
else:
return HttpResponse(
json.dumps({"success": False}),
content_type="application/json"
)
我想要它返回的是:
[{'id': 2, 'title': 'Tennis'}, {'id': 4, 'title': 'Basket'}]
相反，我收到此错误:
TypeError at /ajax/get_shop_categories
[{'id': 2, 'title': 'Tennis'}, {'id': 4, 'title': 'Basket'}] is not JSON serializable
我也用这种方式序列化:
categories = ShopCategory.objects.filter(enabled=True, parent=parent_id)
#json_posts = json.dumps(categories)
#objectQuerySet = ConventionCard.objects.filter(ownerUser = user)
json_posts = serializers.serialize('json', list(categories), fields=('id', 'title'))
但我得到的东西我不喜欢:
[{"fields":{"title":"Tennis"},"pk":2,"model":"appname.shopcategory"},{"fields":{"title":"Basket"},"pk":4,"model":"appname.shopcategory"}]
最佳答案
categories = ShopCategory.objects.filter(enabled=True, parent=parent_id).values('id', 'title')
json_posts = mark_safe(json.dumps(list(categories), ensure_ascii=False))
关于python - Django 对象不可 JSON 序列化，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/27675213/
