Django Abstract User - 如何使用 allauth

问题描述

我没有可以依赖的标准 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结合？

我试图通过删除/包含方面来调整一个功能正常的电子商务网站，其中一个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，由于其社交登录方便，因此必须在此项目中。

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

        user.is_volunteer = True
        user.save()
        volunteer = Volunteer.objects.create(user=user)
        volunteer.interests.add(*self.cleaned_data.get('interests'))
        return user

和 views.py

views.py

from django.contrib.auth import login
from django.shortcuts import redirect
from django.views.generic import CreateView

from .forms import VolunteerSignUpForm
from .models import User

class VolunteerSignUpView(CreateView):
    model = User
    form_class = VolunteerSignUpForm
    template_name = 'registration/signup_form.html'

解决方法

如果您的信号运行不佳，那么您可以单独使用以下信号函数：

@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,**kwargs):
    instance.user.save()

如果仍然不起作用，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

在您的 models.py 中，做一些更改

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 中注册此模型

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
