Set DatetimeField format of django rest framework configuration

I try to use DRF serializers to serialize a model object. I find the DatetimeField in object won't output "2015-10-21T09:28:53.769000Z" of the ISO-8601 format

I lookup DRF document why I can't output ISO-8601 format. According to datetimefield says:

format - A string representing the output format. If not specified, this defaults to the same value as the DATETIME_FORMAT settings key, which will be 'iso-8601' unless set. Setting to a format string indicates that to_representation return values should be coerced to string output. Format strings are described below. Setting this value to None indicates that Python

It means It's default to output iso-8601 format if I never set DATETIME_FORMAT argument? Not yet, it's still no change.

When I try to write setting of django project as the following:

REST_FRAMEWORK = {
    'DATETIME_FORMAT': "iso-8601",
}

or I write in DatetimeField argument as the following:

class UserSerializer(...):
    last_login = DatetimeField(format='iso-8601')
    class Meta:
        model = User
        fields = ('email', 'displayname', 'is_active',
                  'date_joined', 'last_login')

It's still no change again.

Anyone know how to set it?

If you don't konw what happen and you still don't slove that, I can define a datettime format in setting as the following:

REST_FRAMEWORK = {
    'DATETIME_FORMAT': "%Y-%m-%dT%H:%M:%S.%fZ",
}

You don't need to define DATETIME_FORMAT in settings or format in last_login field as iso-861 is the default format.

Here is a sample example showing the serialized output of a datetime field in iso-861 format.

In [1]: from rest_framework import serializers

In [2]: from datetime import datetime

In [3]: class SomeSerializer(serializers.Serializer):
   ....:     last_login = serializers.DateTimeField()
   ....:     

In [4]: x = SomeSerializer(data={'last_login':datetime.now()})

In [5]: x.is_valid()
Out[5]: True

In [6]: x.data # representation of 'last_login' will be in iso-8601 formatted string
Out[6]: OrderedDict([('last_login', u'2015-10-22T09:32:02.788611Z')])
