Django模板邮件“dict”对象没有“get\u host”属性

Question

我试图在用户使用django模板邮件注册帐户后发送验证电子邮件。 这是创建用户后出现的错误： AttributeError 'dict' object has no attribute 'get_host'

所以Django正在尝试调用get_host（），但无法？所以这是一个错误，因为它无法检索我的主机名？ 有人能指出我遗漏了什么吗？你知道吗

class UserListView(generics.ListCreateAPIView):

    serializer_class = UserSerializer

    def perform_create(self, serializer):
        user = serializer.save()
        context = {'user': user}
        to = user.email
        email.ActivationEmail(context).send(to)

class UserSerializer(serializers.ModelSerializer):

    class Meta:
        model = User
        fields = ('id', 'password', 'email')
        extra_kwargs = {'password': {'write_only': True}}

    def create(self, validated_data):
        password = validated_data.pop('password')
        user = super(UserSerializer, self).create(validated_data)
        user.set_password(password)
        user.save()
        return user

class ActivationEmail(BaseEmailMessage):
    template_name = 'email/activation.html'

    def get_context_data(self):
        context = super(ActivationEmail, self).get_context_data()

        user = context.get('user')
        context['uid'] = utils.encode_uid(user.pk)
        context['token'] = default_token_generator.make_token(user)
        context['url'] = 'verify/{uid}/{token}'.format(**context)
        return context

非常感谢您的帮助。你知道吗

Answer 1

ActivationEmail将request作为其初始值设定项的第一个位置参数。您正在传递context作为第一个位置参数，这将导致ActivationEmail失效。你知道吗

确保在创建时将request实例以及context传递给ActivationEmail。你知道吗

email.ActivationEmail(self.request, context).send(to)

Answer 2

您错误地实例化了ActivationEmail。request参数应该是HttpRequest对象，而不是dict。你知道吗
