Django rest framework: Obtain auth token using email instead username
I'm working on a project to enable the django rest framework authentication for mobile devices. I'm using the default token authentication for get the user token from a post request sending username and password.
curl --data "username=username&password=password" http://127.0.0.1:8000/api/api-token-auth/
(api/api-token-auth/ is the url configured with the obtain_auth_token view)
urlpatterns = [
url(r'^api/api-token-auth/', obtain_auth_token),
url(r'^', include(router.urls)),
]
and the response is the user token.
{"token":"c8a8777aca969ea3a164967ec3bb341a3495d234"}
I need to obtain the user token auth using email-password on the post instead username-password, or both. I was reading the documentation of custom authentication http://www.django-rest-framework.org/api-guide/authentication/#custom-authentication... but really, isn't very clear to me. It's very helpful to me... thanks :).
Ok,I found a way for get the auth token using email or username... This is the serializer:
class AuthCustomTokenSerializer(serializers.Serializer):
email_or_username = serializers.CharField()
password = serializers.CharField()
def validate(self, attrs):
email_or_username = attrs.get('email_or_username')
password = attrs.get('password')
if email_or_username and password:
# Check if user sent email
if validateEmail(email_or_username):
user_request = get_object_or_404(
User,
email=email_or_username,
)
email_or_username = user_request.username
user = authenticate(username=email_or_username, password=password)
if user:
if not user.is_active:
msg = _('User account is disabled.')
raise exceptions.ValidationError(msg)
else:
msg = _('Unable to log in with provided credentials.')
raise exceptions.ValidationError(msg)
else:
msg = _('Must include "email or username" and "password"')
raise exceptions.ValidationError(msg)
attrs['user'] = user
return attrs
In the email_or_username field, the user can send the email or the username, and using the function validateEmail(), we can check if the user is trying to login using email or username. Then, we can make the query for get the user instance if is valid, and authenticate it.
This is the view.
class ObtainAuthToken(APIView):
throttle_classes = ()
permission_classes = ()
parser_classes = (
parsers.FormParser,
parsers.MultiPartParser,
parsers.JSONParser,
)
renderer_classes = (renderers.JSONRenderer,)
def post(self, request):
serializer = AuthCustomTokenSerializer(data=request.data)
serializer.is_valid(raise_exception=True)
user = serializer.validated_data['user']
token, created = Token.objects.get_or_create(user=user)
content = {
'token': unicode(token.key),
}
return Response(content)
and then:
curl --data "email_or_username=emailorusername&password=password" http://127.0.0.1:8000/api/my-api-token-auth/.
It's ready.
Write these requirements into your settings.py
ACCOUNT_AUTHENTICATION_METHOD = 'email'
ACCOUNT_EMAIL_REQUIRED = True
ACCOUNT_USERNAME_REQUIRED = False
To check, send this json format request to your server:
{
"username":"youremail@mail.domain",
"password":"Pa$$w0rd"
}
There is a cleaner way to get the user token.
simply run manage.py shell
and then
from rest_framework.authtoken.models import Token
from django.contrib.auth.models import User
u = User.objects.get(username='admin')
token = Token.objects.create(user=u)
print token.key
