django - Unabe to get token from DRF get-token api -

my custom signup api

from rest_framework import viewsets rest_framework import serializers  class signupserializer(serializers.serializer):     email = serializers.emailfield(required=true)     password = serializers.charfield(required=true, write_only=true)      def validate_email(self, val):         try:             user.objects.get(username=val)             raise serializers.validationerror("email-id exist")         except user.doesnotexist:             return val  class signupview(viewsets.modelviewset):      serializer_class = signupserializer      def create(self, request, *args, **kwargs):         serializer = self.get_serializer(data=request.data)         serializer.is_valid(raise_exception=true)         data = serializer.data          email = data.get('email')         password = data.get('password')          u = user(email=email, username=email)         u.set_password(password)         u.save()          data = {             'message': 'successfully created!',             'data': {'id': u.id, 'email': email},         }         return response(data) 

toekn api

from rest_framework.authtoken import views urlpatterns = [     url(r'^api-token-auth/', views.obtain_auth_token), ] 

when hit signup api, returns success response, mean

{ 'message': 'successfully created!', 'data': {'id': 1, 'email': 'xyz@gmail.com'} }

but when try generate/get token user using above token api, says ..invalid credentials?

{   "non_field_errors": [     "unable log in provided credentials."   ] } 

however if create user using management command createsuperuser , use same api token works?

is there someting wrong in signup api?

you should remove write_only=true serializer. fix error.
