Django过滤日期时间元素

Question

I use django 1.11.2 for my project. I had defined some models and all work right.

Now I need to get some data from one of my models by date. For example all entry which have month=8, month=9....

I have this, MyModel(....some fields...., created_date) and in models.py I have:

....
created_date=models.DateTimeField()
....
....
self.created_date=(datetime.now())
....

Created_date is a datetime field and its values are in this format: YYYY-MM-DD HH:MM:SS, for example 2017-08-31 14:25:58.

So, I see this: https://docs.djangoproject.com/en/1.11/ref/models/querysets/#month

And this will be perfect for me, but doesn't work.

From shell I write this:

>>> from project.models import MyModel
>>> from datetime import *
>>> MyModel.objects.all() ---> Work ok, I get all entries
>>> MyModel.objects.filter(created_date__month=8)
<QuerySet []>

In this case I get an empty Quertset.

You may probably need to set USE_TZ into False in settings.py file

USE_TZ = False

If it is set as True ie timezone enabled, then the __month lookup will not work
