Implementation Example? about django-graphql-jwt

Hey @evanheckert!

welcome to GraphQL.

you can use a resolver method for the token and others non-model fields:
http://docs.graphene-python.org/en/latest/types/objecttypes/#resolvers

import graphene

from django.contrib.auth import get_user_model
from graphene_django import DjangoObjectType

from graphql_jwt.utils import jwt_encode, jwt_payload

class UserNode(DjangoObjectType):
    token = graphene.String()

    class Meta:
        model = get_user_model()
        filter_fields = [
            'username',
        ]
        interfaces = (relay.Node,)

        def resolve_token(self, info, **kwargs):
            if info.context.user != self:
                return None

            payload = jwt_payload(self)
            return jwt_encode(payload)

Add Django login function to your mutation to attach authenticated user to the current session:
https://docs.djangoproject.com/en/1.11/topics/auth/default/#how-to-log-a-user-in

import graphene

from django.contrib.auth import authenticate, login

class LogIn(graphene.Mutation):
    user = graphene.Field(UserNode)

    class Arguments:
        username = graphene.String()
        password = graphene.String()

    @classmethod
    def mutate(cls, root, info, username, password):
        user = authenticate(username=username, password=password)

        if user is None:
            raise Exception('Please enter a correct username and password')

        if not user.is_active:
            raise Exception('It seems your account has been disabled')

        login(info.context, user)
        return cls(user=user)

@mongkok Thank you! I only had to change one thing in the example you provided - your code raises an exception if it does find a user, so I just changed if user is not None: to if user is None: and it works!

Thank you so much for your help!

Hi @evanheckert, I think is not good idea to include the token as a UserNode field (using cookie-based sessions..),
the user must authenticate each time he wants to retrieve the token.

from django.contrib.auth import authenticate, login

import graphene
from graphql_jwt.shortcuts import get_token


class LogIn(graphene.Mutation):
    token = graphene.String()
    user = graphene.Field(UserNode)

    class Arguments:
        username = graphene.String()
        password = graphene.String()

    @classmethod
    def mutate(cls, root, info, username, password):
        user = authenticate(username=username, password=password)

        if user is None:
            raise Exception('Please enter a correct username and password')

        if not user.is_active:
            raise Exception('It seems your account has been disabled')

        login(info.context, user)
        return cls(user=user, token=get_token(user))

Thanks!, README is updated.

@mongkok are you able to make a repository in order to show the structure of project (skeleton)? I mean are you able to show what code in what files should be placed?

Thank you.
