ViewsGoogle authentication using django-rest-auth and allauth
I am trying to create an authentication API for a flutter app that will log users in with a google authentication signup/login form. I followed this tutorial to achieve this.
So far so good, except that the tutorial is based on a GitHub sign in rather than Google. I managed to get it working up till step "connecting" step. I am able to get the code from the redirect but when I access http://127.0.0.1:8000/auth/google/ I see it's asking for a two fields (access_token, code). When I try to just post with the information I do have I get the following error:
"non_field_errors": [
"View is not defined, pass it as a context variable"
]

This is a version conflict error with djangorestframework => 3.12 Solution: Downgrade to djangorestframework <= 3.11.0 and everything should be fine.

Try this:
class GoogleLogin(SocialLoginView):
adapter_class = GoogleOAuth2Adapter
client_class = OAuth2Client
serializer_class = SocialLoginSerializer
def get_serializer(self, *args, **kwargs):
serializer_class = self.get_serializer_class()
kwargs['context'] = self.get_serializer_context()
return serializer_class(*args, **kwargs)
google_login = GoogleLogin.as_view()

I want to add details in the JACKSON MOURA code snippet with an explanation.
In settings.py, you have to do this. I didn't find any good documentation. But it works for social authentication. now you don't need to set up the social auth apps by using the admin panel anymore. I showed samples of Google, Facebook, and LinkedIn. It will work with other social apps as well.
SOCIALACCOUNT_PROVIDERS = {
"google": {
"APP": {
"client_id": "<client_id>",
"secret": "<secret>",
},
},
'facebook': {
"APP": {
"client_id": "<client_id>",
"secret": "<secret>",
},
},
"linkedin": {
"APP": {
"client_id": "<client_id>",
"secret": "<secret>",
}
}
}
Now in view.py, you have to create serializer classes. all will be the same. I am showing for Google, LinkedIn, and Facebook.
class FacebookLogin(SocialLoginView):
adapter_class = FacebookOAuth2Adapter
client_class = OAuth2Client
serializer_class = SocialLoginSerializer
def get_serializer(self, *args, **kwargs):
serializer_class = self.get_serializer_class()
kwargs['context'] = self.get_serializer_context()
return serializer_class(*args, **kwargs)
class GoogleLogin(SocialLoginView):
adapter_class = GoogleOAuth2Adapter
client_class = OAuth2Client
serializer_class = SocialLoginSerializer
def get_serializer(self, *args, **kwargs):
serializer_class = self.get_serializer_class()
kwargs['context'] = self.get_serializer_context()
return serializer_class(*args, **kwargs)
class LinkedInLogin(SocialLoginView):
adapter_class = LinkedInOAuthAdapter
client_class = OAuthClient
serializer_class = SocialLoginSerializer
def get_serializer(self, *args, **kwargs):
serializer_class = self.get_serializer_class()
kwargs['context'] = self.get_serializer_context()
return serializer_class(*args, **kwargs)
Now, the backend is ready for getting post data from the frontend and will show perfect error like below. It will work with all other social apps.

It is because rest_auth is no longer maintained and is not compatible with latest versions of Django Rest Framework.
This error is resolved in switching to dj-rest-auth instead of rest_auth, which is actively maintained fork of the original project.
