Django Social Auth - Google: AttributeError: 'NoneType' 對象沒有屬性 'provider'

Question

我在嘗試通過 google 登錄時收到此錯誤，我已經嘗試了幾乎所有我能想到的方法，而 SO 上的類似問題似乎無濟於事。 我有一個自定義用戶模型設置，如下所示：

模型.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  

表格.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')

社交身份驗證管道

SOCIAL_AUTH_PIPELINE = (
    'social_core.pipeline.social_auth.social_details',
    'social_core.pipeline.social_auth.social_uid',
    'social_core.pipeline.social_auth.auth_allowed',
    'social_core.pipeline.social_auth.social_user',
    'social_core.pipeline.user.get_username',
    'social_core.pipeline.social_auth.associate_by_email',
    'social_core.pipeline.user.create_user',
    'social_core.pipeline.social_auth.associate_user',
    'social_core.pipeline.social_auth.load_extra_data',
    'social_core.pipeline.user.user_details'
)

我猜這與我創建的自定義用戶模型有關，因為我事先沒有遇到過這個問題。 任何幫助將非常感激。

鏈接上的錯誤與您在標題中提到的不符。 對於回溯，解決方案只是添加以下內容：

SESSION_COOKIE_SECURE = False
