AttributeError: l'objet 'dict' n'a pas d'attribut 'user' lors de la substitution de "social-app-auth-django" create_user

Question

J'ai remarqué que le SAAD ne parvient pas à associer un utilisateur existant à l'utilisateur connecté social-auth. Cela crée plusieurs utilisateurs avec la même adresse e-mail. J'ai essayé de corriger cela en commentant dans settings.py,

# 'social_core.pipeline.user.create_user', 

Je me suis alors fait en vue de créer un profil d'utilisateur. J'ai ajouté ce pipeline,

SOCIAL_AUTH_PIPELINE = (
... 
'accounts.views.save_profile', 
... 
) 

En accounts.views,

def save_profile(backend, user, response, *args, **kwargs): 
    username = "" 
    if backend.name == "google-oauth2": 
     email = response["emails"][0]["value"] 
     existing_user = User.objects.get(email=email) 
     username = existing_user.username 
     password = existing_user.password 
     authenticated_user = authenticate(username=username, password=password) 
     login(request,authenticated_user) # I need request to login the user 

Le problème ici est que je dois demande de vous connecter à l'utilisateur. Le login nécessite une requête et un utilisateur authentifié en tant que paramètres. Supposons que j'ajoute une requête en paramètre, j'obtiens un AttributeError: 'dict' object has no attribute 'user'.

def save_profile(request, backend, user, response, *args, **kwargs): 
    username = "" 
    if backend.name == "google-oauth2": 
     email = response["emails"][0]["value"] 
     existing_user = User.objects.get(email=email) 
     username = existing_user.username 
     password = existing_user.password 
     authenticated_user = authenticate(username=username, password=password) 
     login(request,authenticated_user) 

Comment se connecter à l'utilisateur, ayant un nom d'utilisateur et un mot de passe connus?

Tout ce que je faisais était ajouter social_core.pipeline.social_auth.associate_by_email à la canalisation au-dessus create_user. Maintenant, il vérifie s'il y a un compte déjà lié avec l'email social-auth obtenu. Si ce n'est pas le cas, cela crée un nouvel utilisateur.

SOCIAL_AUTH_PIPELINE = (
    ... 
    'social_core.pipeline.social_auth.associate_by_email', 
    'social_core.pipeline.user.create_user', 
    'accounts.views.save_profile', 
    'social_core.pipeline.social_auth.associate_user', 
    ... 
) 

Le def save_profile ressemble:

def save_profile(backend, user, response, *args, **kwargs): 
    if backend.name == "google-oauth2": 
     # A dot in username will have url issues 
     username = user.username.replace(".","_") 
     user.username = username 
     user.first_name = user.first_name.capitalize() 
     user.last_name = user.last_name.capitalize()
