Django Social Auth - Google: AttributeError: 'NoneType' object has no attribute 'provider'

I am receiving this error when trying to login via google, I've tried just about everything I can think of and similar issues on SO don't seem to help. I have a custom user model setup as such:
models.py
from django.contrib.auth.models import AbstractUser
from django.db import models
class Departments(models.Model):
name = models.CharField(max_length=255, unique=True)
def __str__(self):
return self.name
class AlluredUser(AbstractUser):
departments = models.ManyToManyField(Departments)
def __str__(self):
return self.username
forms.py
from django import forms
from django.contrib.auth.forms import UserCreationForm, UserChangeForm
from .models import AlluredUser
class CustomUserCreationForm(UserCreationForm):
class Meta:
model = AlluredUser
fields = ('username', 'email')
class CustomUserChangeForm(UserChangeForm):
class Meta:
model = AlluredUser
fields = ('username', 'email')

I'm guessing it has something to do with the custom user model I created since I didn't have this problem beforehand. Any help would be much appreciated.

The error on the link doesn't match what you mention in the title.
For the traceback, the solution is just to add this:
SESSION_COOKIE_SECURE = False

This issue appears since I have changed my init fonction, for the form that I use in my view :
Forms:
class Groupe_Form(forms.ModelForm) :
def __init__(self, nom_groupe, *args, **kwargs):
super(Groupe_Form,self).__init__(*args, **kwargs)
self.fields['pod'].widget = forms.Select()
pod1 = Groupe.objects.filter(nom_groupe = nom_groupe).values_list('pod', flat = True)
pods = list(pod1)
self.fields['pod'].queryset = Pod.objects.filter(id__in=pods)
class Meta:
model = Groupe
fields = ['pod']
Views :
def groupe_pod(request):
global new_groupe
grp = new_groupe
form = forms.Groupe_Form(request.POST, grp)
if request.method == 'POST':
if form.is_valid():
print "form was valid"
data_groupe_pod = request.POST.get('grp_pod')
print "data_groupe :", data_groupe_pod
global new_cours
print new_cours
if new_cours == "ICND1":
return redirect('http://127.0.0.1:8000/icnd_1')
elif new_cours == "ICND2":
return redirect('http://127.0.0.1:8000/icnd_2')
else :
form = forms.Groupe_Form(new_groupe)
return render(request, 'pod.html', locals())
I've tried many things, I really don't know where is the problem in my Django code.

Your form's __init__ method is:
def __init__(self, nom_groupe, *args, **kwargs):
Therefore you should instantiate it with:
form = forms.Groupe_Form(grp, request.POST)
You currently have the arguments the other way round.

Your __init__ signature has as its first parameter nom_groupe. In form = forms.Groupe_Form(request.POST, grp) you pass request.POST as the first parameter. You have to switch the parameters:
form = forms.Groupe_Form(grp, request.POST)

Django - one to one serializer Create function

I extended the default User model to ExtendedUser:
from django.db import models
from django.contrib.auth.models import User
class ExtendedUser(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)
shirt_size = models.CharField(max_length=2)
User serializer:
from django.contrib.auth.models import User
from rest_framework import serializers
class UserSerializer(serializers.ModelSerializer):
class Meta:
model = User
fields = ('url', 'username', 'email', 'groups', 'is_staff')
ExtendedUser serializer:
from api.resources.users.models.extended_user import ExtendedUser
from rest_framework import serializers
from django.contrib.auth.models import User
from api.resources.users.serializers.user import UserSerializer
class ExtendedUserSerializer(serializers.HyperlinkedModelSerializer):
user = UserSerializer(read_only=False)
class Meta:
model = ExtendedUser
fields = ('url', 'shirt_size', 'user')
def create(self, validated_data):
user_data = validated_data.pop('user')
user = User.objects.create(**user_data)
return ExtendedUser.objects.create(user=user, **validated_data)
The main result should be that on submitting new ExtendedUser it will create a user too with one to one realation.
But I am getting this error:
User: myusername needs to have a value for field "user" before this
many-to-many relationship can be used.

Okay for starters, the problem has nothing to do with django-rest-framework or your python version.
It seems to be an issue with django==1.10 as I simply tried:
User.objects.create(user="hello", email="333.22#eewofw.com", groups=[], is_staff=False)
in django's shell and received the exact same error. However, if we try newer versions of django, the problem does not persist.
I have noticed that when installing django using this command:
pip install django
It will install django==1.10 and not the latest version. If you mistakenly installed this older version, I suggest to uninstall django and then install the latest version:
pip uninstall django
pip install django==1.9.12
When using django==1.9.12, you need to remove groups completely from your UserSerializer and not provide it when doing your POST.

Your update method is not called, because it is a method of the meta class of the serializer (AccountUpdateSerializer.Meta), not the serializer class AccountUpdateSerializer itself.
Here is how it should look:
class AccountUpdateSerializer(serializers.ModelSerializer):
username=serializers.CharField(source ='my_user.username')
class Meta:
model= Account
fields=['id','username','statut','date']
def update(self, instance, validated_data):
print(instance)
instance.statut = validated_data.get('statut', instance.statut)
instance.my_user.username = validated_data['username']
return instance
(Or did you just post your code incorrectly?)

Okay, I think I figured it out... I'm using a variable/column called "clean". Django's admin interface has a method called "clean()" also, which does some kind of validation. It appears that there was some kind of naming conflict so I changed the variable to name to "cleaned" and then to make sure that it knows what database field to use (I'm using a legacy/preexisting db), I added a db_column option:
cleaned = models.TextField(blank=True,db_column="clean")
It would have been nice to know that "clean" was a reserved identifier in django but at least I only wasted half a day on this django stuff which ostensibly makes database operations easier. To be fair, I just started django this morning and if I would have found and answer on stackoverflow it would have been a breeze to fix.
If anyone knows a better way to handle this, let me know...
