如何在Django Rest Framework中删除用户帐户？

Question

我正在通过结合Django Rest Framework和Angular创建一个应用程序。
请告知我们有关用户删除的实现，因为有些地方无法使用。

我在Djnago的views.py中对删除视图进行了如下描述。

class AuthInfoDeleteView(generics.DestroyAPIView):
    permission_classes = (permissions.IsAuthenticated,)
    serializer_class = AccountSerializer
    lookup_field = 'email'
    queryset = Account.objects.all()

    def get_object(self):
        try:
            instance = self.queryset.get(email=self.request.user)
            return instance
        except Account.DoesNotExist:
            raise Http404

电子邮件存储在self.request.user 。
另外，我在serializer.py中编写如下。

from django.contrib.auth import update_session_auth_hash
from rest_framework import serializers

from .models import Account, AccountManager


class AccountSerializer(serializers.ModelSerializer):
    password = serializers.CharField(write_only=True, required=False)

    class Meta:
        model = Account
        fields = ('id', 'username', 'email', 'profile', 'password', )

    def create(self, validated_data):
        return Account.objects.create_user(request_data=validated_data)

在这种状态下，将Angular的DELETE方法发送到AuthInfoDeleteView所链接到的URL（/ api / user / delete /）时，发生以下错误。

Internal Server Error: /api/user/delete/

如何正确正确删除帐户？
我需要你的帮助。

Answer 1

尝试像这样编辑视图，

try: 
    instance = self.queryset.get(email=self.request.user.email) 
    return instance 
except Account.DoesNotExist: 
    raise Http404

Answer 2

为什么不禁用帐户而不是删除帐户？

那是我的方法。 在我的视图类（用于扩展的UserProfile并从RetrieveUpdateDestroyAPIView继承的视图类）中，我覆盖了destroy方法，如下所示：

def destroy(self, request, pk=None, **kwargs):

    request.user.is_active = False
    request.user.save()

    return Response(status=204)

我使用令牌身份验证（使用rest_auth），并且在禁用帐户后，令牌不再有效（尝试使用令牌时，响应为“用户未激活或已删除”）。

我认为最好的做法是禁用帐户而不是删除帐户。
