AttributeError：“dict”对象在覆盖“social-app-auth-django”create_user 期间没有属性“user”

Question

我注意到SAAD 无法将现有用户与已登录的 social-auth 用户相关联。这是使用相同的电子邮件地址创建多个用户。我试图通过在 settings.py 中注释掉来覆盖它，

# 'social_core.pipeline.user.create_user',

然后我创建了一个用户配置文件。我在管道中添加了这个，

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

在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 

这里的问题是我需要请求登录用户。登录需要请求和经过身份验证的用户作为参数。假设我添加请求作为参数，我得到一个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) 

如果知道用户名和密码，我如何登录用户？

我所做的只是将social_core.pipeline.social_auth.associate_by_email添加到create_user上方的管道中。现在，它会检查是否有一个帐户已经与获得的社交认证电子邮件相关联。如果没有，它会创建一个新用户。

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',
    ...
)

def save_profile 看起来像：

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()
