Django模板日期格式

Question

我试图在MongoDB数据库中记录一些时间和日期。但是我无法让它们正确显示。在数据库中，它显示为ISODate("2018-11-05T20:57:53.233Z")，但是当我尝试显示日期时，它显示为{'$date': 1541451473242}。如果我使用value|date:"m d Y"，它将完全不显示。我将在下面发布我的模型代码。

Model.py

class Promotion_Code_Info(EmbeddedDocument):
    promo_code = StringField(max_length=200, required=True)
    code_active = BooleanField(default = True)
    use_number = IntField(required=True)
    sent_when = DateTimeField(required=False)
    customer_email = EmailField(required=False)
    code_added = DateTimeField(default=datetime.datetime.utcnow)
    code_exp = DateTimeField(default=datetime.datetime.utcnow)


class Promotion_Lists(Document):
    user_id = IntField(required=True)
    unique_promo_id = StringField(max_length=16, required=True)
    promo_name = StringField(max_length=200, required=True)
    code_list = ListField(EmbeddedDocumentField(Promotion_Code_Info))
    amount_active = IntField(required=True)
    amount_used = IntField(required=True)
    total = IntField(required=True)
