django - 使用 google django 创建社交身份验证功能

问题描述

您好，我是新手，有任务要做，我尝试了简单的社交身份验证，但下面有点复杂：

Create a social authentication functionality with google and add user in a
database. After adding user in a database, customer should also be created
using django signals.
Note:- Customer is one to one related with user?

我的模型.py：

class Buddy(models.Model): 
    user_name=models.CharField(max_length=200,blank=True,null=True) 

    def __str__(self): 
        return str(self.user_name) 


class Customer(models.Model): 
    customer_name=models.OneToOneField(Buddy,
                                       on_delete = models.CASCADE,
                                       blank=True,null=True) 
    def __str__(self): 
         return str(self.customer_name)

我的settings.py包括以下几行：

SOCIAL_AUTH_GOOGLE_OAUTH2_KEY = '2377[...].apps.googleusercontent.com' 
SOCIAL_AUTH_GOOGLE_OAUTH2_SECRET = '[...]' 
SOCIAL_AUTH_GOOGLE_OAUTH2_SCOPE = ['email'] 
INSTALLED_APPS = [ ... # oauth 
                  'oauth2_provider', 
                  'social_django', 
                  'rest_framework_social_oauth2' ] 

AUTHENTICATION_BACKENDS = ( # Google OAuth2 
   'social_core.backends.google.GoogleOAuth2', 
    # django-rest-framework-social-oauth2                            
   'rest_framework_social_oauth2.backends.DjangoOAuth2', # Django 
   'django.contrib.auth.backends.ModelBackend', )

解决方案

您必须使用 Django 的post_save信号。

在你的models.py中有：

class Buddy(models.Model): 
    user_name=models.CharField(max_length=200, blank=True, null=True) 

    def __str__(self): 
        return str(self.user_name) 


class Customer(models.Model): 
    # This translates into buddy_id when you migrate
    buddy=models.OneToOneField(Buddy,on_delete = models.CASCADE,
                               blank=True, null=True) 
    customer_name = models.CharField(max_length=200, blank=True, null=True) 

    def __str__(self): 
        return str(self.customer_name)

在你的views.py中确保你有

from django.shortcuts import render
from django.db.models.signals import post_save
from .models import Buddy
from .callbacks import save_customer

# You'll customize this view to read any parameters and provide user_name
def custom_view(request):
     Buddy.objects.create(user_name="SomeUsername")
     # Any of your other logic comes here, specify in the dict 
     return render(request, 'yourpage.html', {})


# This should be at the bottom of your views.py:
post_save.connect(save_customer, sender=Buddy)

然后在同一位置创建一个名为callbacks.py的新文件，其中包括：

from .models import Buddy
from django.db.models.signals import post_save
from django.dispatch import receiver

@receiver(post_save, sender=Buddy)
def save_customer(sender, instance, **kwargs):
    # Customize your OneOnOne model on a meaningful way so it will be useful
    customer = Customer.objects.create(customer_name=instance.user_name) 
    instance.customer = customer
    instance.customer.save()
