Django Abstract User - 如何用 allauth 实现它

Question

我没有可依赖的标准 Django 用户模型。您将如何结合 AbstractUser 和 Allauth。我应该先构建视图“SignUpView.as_view”还是应该弄清楚路径“accounts/”应该如何与 allauth 关联？

我试图通过删除/包含方面来调整正常运行的电子商务网站，其中一种调整是自定义用户模型。

我正在学习本教程：

https://simpleisbetterthancomplex.com/tutorial/2018/01/18/how-to-implement-multiple-user-types-with-django.html

非常好，只是不知道如何容纳 allauth，由于其社交登录的便利性，它必须在这个项目中。

urls.py

from django.contrib import admin
from django.urls import path, include
from django.conf import settings
from django.conf.urls.static import static


urlpatterns = [
    path('', include('home.urls')),
    path('admin/', admin.site.urls),
    path('accounts/', include('allauth.urls')),
    path('projects/', include('projects.urls')),
    # path('profiles/', include('profiles.urls')),
    # path('accounts/signup/', users.SignUpView.as_view(), name='signup'),
    # path('accounts/signup/volunteer/', volunteers.VolunteerSignUpView.as_view(), name='volunteer_signup'),
    # path('accounts/signup/organisation/', organisations.OrganisationsSignUpView.as_view(), name='organisation_signup'),
] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

models.py

from django.contrib.auth.models import AbstractUser
from django.db import models
from django.utils.html import escape, mark_safe


class User(AbstractUser):
    is_volunteer = models.BooleanField(default=False)
    is_organisation = models.BooleanField(default=False)



class Volunteer(models.Model):
   
    user = models.OneToOneField(User, on_delete=models.CASCADE, primary_key=True)

    def __str__(self):
        return self.user.username

Answer 1

如果您的信号效果不佳，那么您可以单独使用以下信号功能：

@receiver(post_save, sender=User)
def create_profile(sender, instance, created, **kwargs):
    if created:
        User.objects.create(user=instance)

@receiver(post_save, sender=User)
def save_profile(sender, instance, **kwargs):
    instance.user.save()

如果仍然无法正常工作，那么您可以创建一个名为 signals.py 的单独文件，然后复制并粘贴我上面编写的所有代码。 问候阿布巴卡尔

首先删除您的数据库和所有迁移文件夹，然后进行以下更改

在你的models.py中，做一些改变

from django.conf import settings

class Volunteer(models.Model):
   
    user = models.OneToOneField(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, primary_key=True)

    def __str__(self):
        return self.user.username 

并在 admin.py 中注册这个模型

from django.contrib import admin

from .models import *

admin.site.register(User)

进行以下更改后 运行以下命令

python manage.py makemigrations <your_app_name_in_which_AbstractUserModel_is_present>
python manage.py migrate
