how to customize django jwt graphql authentication - django

Question

Hi I'm trying to customize
jwt graphql Django default authentication
I need to achieve log in with username or email
normal Django we customized authentication backend.
mutation{
tokenAuth(username:"myemail#email.com"
password:"pass")
{
token
}
}
Authenticate with username
mutation{
tokenAuth(username:"myname"
password:"pass")
{
token
}
}
the normal username is working fine.
how I can authenticate the user by username or email in jwt graphql
I tried this link
https://django-graphql-jwt.domake.io/en/latest/customizing.html
I don't get any idea about that...
Does anyone have any idea about that??

Answer 1

You have to make the changes on the Model level not in JWT, JWT will follow, because JWT is only a presentation of what is going on behind the scenes.
Look at the link under here, maybe it will help you! :)

Disclaimer - mama's answer should work. Halfway through writting an answer I realised I'm wrong, but I still wanna show you what I wanted to suggest. It shows what JWT TokenAuth mutation does and a way to tap into that completely.
change the inbuild Django authentication like mama's answer suggests
rewrite graphql_jwt.decorators.token_auth to look at both fields, not just one
write your own class for the TokenMutation that uses this decorator on it's mutate function
Something like so (untested):
def two_field_token_auth(f):
#wraps(f)
#setup_jwt_cookie
#csrf_rotation
#refresh_expiration
def wrapper(cls, root, info, password, **kwargs):
context = info.context
context._jwt_token_auth = True
username = kwargs.get('username')
email = kwargs.get('email')
user = your_auth_method(
request=context,
username=username,
email=email,
password=password,
)
if user is None:
raise exceptions.JSONWebTokenError(
_('Please enter valid credentials'),
)
if hasattr(context, 'user'):
context.user = user
result = f(cls, root, info, **kwargs)
signals.token_issued.send(sender=cls, request=context, user=user)
return maybe_thenable((context, user, result), on_token_auth_resolve)
return wrapper
class TwoFieldJWTMutation(JSONWebTokenMutation):
#classmethod
#two_field_token_auth
def mutate(cls, root, info, **kwargs):
return cls.resolve(root, info, **kwargs)
