Question

我已经实现了DRF，并且不想强制进行电子邮件验证，但仍然可以使用它（在屏幕上提醒他们）。我只想返回account_emailaddress.verified以及用户端点。实现此目标的最佳方法是什么？我尝试从此post中获取提示，但没有成功。

account_emailaddress来自我已实现的django-allauth应用 https://github.com/pennersr/django-allauth/blob/master/allauth/account/models.py

序列化器：

class UserSerializer(serializers.ModelSerializer):
class Meta:
    model = models.CustomUser
    fields = ('id', 'first_name', 'last_name', 'email', 'phone_number', 'avatar')

查看：

class UserView(generics.RetrieveUpdateDestroyAPIView):
queryset = CustomUser.objects.all()
serializer_class = UserSerializer

def get(self, request, *args, **kwargs):
    try:
        user = self.queryset.get(pk=kwargs["user"])
        return Response(UserSerializer(user).data)
    except CustomUser.DoesNotExist:
        return Response(
            data={
                "message": "User with id: {} does not exist".format(kwargs["user"])
            },
            status=status.HTTP_404_NOT_FOUND
        )

def put(self, request, *args, **kwargs):
    try:
        user = self.queryset.get(pk=kwargs["user"])
        serializer = UserSerializer()
        user = serializer.update(user, request.data)
        return Response(UserSerializer(user).data)
    except CustomUser.DoesNotExist:
        return Response(
            data={
                "message": "User with id: {} does not exist".format(kwargs["user"])
            },
            status=status.HTTP_404_NOT_FOUND
        )

编辑：感谢schillingt的回答，我能够修改序列化程序以根据需要工作

from allauth.account.models import EmailAddress    

class UserSerializer(serializers.ModelSerializer):
verified_email = serializers.SerializerMethodField()
class Meta:
    model = models.CustomUser
    fields = ('id', 'first_name', 'last_name', 'email', 'phone_number', 'avatar', 'verified_email')

def get_verified_email(self, obj):
    try:
        email_address = EmailAddress.objects.get(user_id=obj.id)
        return email_address.verified
    except EmailAddress.DoesNotExist:
        return None

如果我只想在其他序列化程序上使用该字段，我过去所做的方式就是使用SerializerMethod类。我猜上了account_emailaddress的课程。

class UserSerializer(serializers.ModelSerializer):
    verified_email = serializers.SerializerMethod()

    class Meta:
        model = models.CustomUser
        fields = (..., 'verified_email')

    def _verified_email(self, obj):
        try:
            return obj.account_emailaddress.verified
        except EmailAddress.DoesNotExist:
            return None

然后在视图集上，应在account_emailaddress属性的select_related中将queryset包括在内，以免对每个CustomUser进行附加查询。

您可以在序列化器字段上使用源映射，以包括相关模型中的字段，例如（假设已验证是布尔字段）；

class UserSerializer(serializers.ModelSerializer):
    verified = serializers.BooleanField(source='account_emailaddress.verified', read_only=True)

class Meta:
    model = models.CustomUser
    fields = ('id', 'first_name', 'last_name', 'email', 'phone_number', 'avatar', 'verified ')

请注意，这也假设account_emailaddress是CustomUser模型上的一个字段，或者可以通过OneToOne字段像 custom_user.account_emailaddress 一样进行访问。

如何返回已验证的电子邮件以及用户端点？
