pip包django- unixdatetimefield提供了一个UnixDateTimeField字段，您可以为此开箱即用（ https：// pypi）。 python.org/pypi/django-unixdatetimefield/ ）。

示例模型：

  from django_unixdatetimefield import UnixDateTimeField 

 class MyModel（models.Model）：
 created_at = UnixDateTimeField（）
 pre> 

 Python ORM查询：
 >>> m = MyModel（）
>>> m.created_at = datetime.datetime（2015，2，21，19，38，32，209148）
>>> m.save（）
 
数据库：
 源码>从mymodel中选择created_at; 
 1426967129

i'd like to make the DateTimefield of models accept unix timestamp (in seconds) values.  

I found this but the acepted solution doesn't work?
unixtimestamp input in DataTimeField  

i.e. i don't see how adding '%s' as an input format will work, especially when the code for to_python() of the standard datetime field doesn't include any logic for handling unix timestamps.

If there is a setting that allows me to do this great.

Otherwise, what I think i want is to subclass DateTimeField and somehow automatically convert the int to a datetime object when i set the value. I want to do this before saving instead of overriding save() because i want consistency when retrieving the value of this  field. i.e. when I take the value out, I don't want to worry about if i have a datetime object or an int regardless of if the instance has been saved or not.

I looked at source of django.db.models.fields and it's not apparent to me.
The pip package django-unixdatetimefield provides a UnixDateTimeField field that you can use for this out of the box (https://pypi.python.org/pypi/django-unixdatetimefield/).

Example model:
from django_unixdatetimefield import UnixDateTimeField

class MyModel(models.Model):
    created_at = UnixDateTimeField()
Python ORM query:
>>> m = MyModel()
>>> m.created_at = datetime.datetime(2015, 2, 21, 19, 38, 32, 209148)
>>> m.save()
Database:
sqlite> select created_at from mymodel;
1426967129
