django rest framework序列化属性字段作为日期？

Question

I have this :

extra_kwargs = {
    'posting_date': {'format':'%d-%m-%Y'},
    'validation_date': {'format':'%d-%m-%Y'},
    'execution_date': {'format':'%d-%m-%Y'},
    'rejection_date': {'format':'%d-%m-%Y'},
    'deadline': {'format':'%d-%m-%Y'}
}

Every thing works fine with first 4 fields since they are datetime django model field. the last one (deadline) is a property and It's not treated as datetime by django serializer even if it returns a datetime so using format raises an exception.

Any solution for this issue ?

Answer 1

You can always convert a string to a python datetime object, like this:

from datetime import datetime

# strptime stands for "from string parse the (date)time"
datetime_obj = datetime.strptime('Jan 30 2017 17:00PM', '%b %d %Y %I:%M%p')
