Hi Folks,
I didn't understand this code, Cab you guys please explain me about this
code:
*views.py:*
*-------------*
*class UserLoginAPIView(GenericAPIView): authentication_classes = ()
permission_classes = () serializer_class = UserLoginSerializer ()def
post(self, request, *args, **kwargs): serializer =
self.get_serializer(data=request.data) if serializer.is_valid(): user =
serializer.user *
*token, _ = Token.objects.get_or_create(user=user) return
Response(data=TokenSerializer(token).data, status=status.HTTP_200_OK) else:
return Response(data=serializer.errors,status=status.HTTP_400_BAD_REQUEST,)*
*seralizers.py*
*-----------------*
*class UserLoginSerializer(serializers.Serializer): username =
serializers.CharField(required=True) password =
serializers.CharField(required=True) default_error_messages = {
'inactive_account': _('User account is disabled.'),
'invalid_credentials': _('Unable to login with provided credentials.')
} def __init__(self, *args, **kwargs): super(UserLoginSerializer,
self).__init__(*args, **kwargs) self.user = None def
validate(self, attrs): self.user =
authenticate(username=attrs.get("username"),
password=attrs.get('password')) if self.user: if not
self.user.is_active: raise
serializers.ValidationError(self.error_messages['inactive_account'])
return attrs else: raise
serializers.ValidationError(self.error_messages['invalid_credentials']*
Here ,
1) super(UserLoginSerializer, self).__init__(*args, **kwargs)
what value parent will get by using line *super(UserLoginSerializer,
self).__init__(*args, **kwargs) *
2) Validate is one method which take attrs as a argument but If I didn;t
pass value of attrs then how it will be work?
Guys please help me to understand this code.
Thank You
Regards,
Soumen
