Question

我创建了一个自定义用户模型：

class CUserManager(BaseUserManager):

    def _create_user(self, email, first_name, password,
                     is_staff, is_superuser, **extra_fields):
        """
        Creates and saves a User with the given email and password.
        """
        now = timezone.now()
        if not email:
            raise ValueError('The given email must be set')
        email = self.normalize_email(email)
        user = self.model(email=email,
                          first_name = first_name,
                          is_staff=is_staff, is_active=False,
                          is_superuser=is_superuser, last_login=now,
                          date_joined=now, **extra_fields)
        user.set_password(password)
        user.save(using=self._db)
        return user

    def create_user(self, email, first_name, password=None, **extra_fields):
        return self._create_user(email, first_name, password, False, False,
                                 **extra_fields)

    def create_superuser(self, email, first_name, password, **extra_fields):
        return self._create_user(email, first_name, password, True, True,
                                 **extra_fields)


class CUser(AbstractBaseUser, PermissionsMixin):
    email = models.EmailField(_('email address'), max_length=254, unique=True)
    first_name = models.CharField(_('first name'), max_length=30)
    last_name = models.CharField(_('last name'), max_length=30, blank=True)
    is_staff = models.BooleanField(_('staff status'), default=False,
        help_text=_('Designates whether the user can log into this admin '
                    'site.'))
    is_active = models.BooleanField(_('active'), default=False,
        help_text=_('Designates whether this user should be treated as '
                    'active. Unselect this instead of deleting accounts.'))
    date_joined = models.DateTimeField(_('date joined'), default=timezone.now)
    last_updated = models.DateTimeField(_('last updated'), default=timezone.now)
    image = ProcessedImageField(upload_to= generate_random_filename,
                                processors=[ResizeToFill(640, 640)],
                                format='JPEG',
                                options={'quality': 60})

    objects = CUserManager()

    USERNAME_FIELD = 'email'
    REQUIRED_FIELDS = ['first_name', 'last_name']

    def save(self, *args, **kwargs):
        try:
            this = CUser.objects.get(id=self.id)
            if this.image != self.image:
                this.image.delete()
        except: pass
        super(CUser, self).save(*args, **kwargs)

我的注册序列化器：

class UserRegistrationSerializer(serializers.ModelSerializer):
    password = serializers.CharField(style={'input_type': 'password'},
                                     write_only=True,
                                     validators=settings.get('PASSWORD_VALIDATORS'))
    class Meta:
        model = User
        fields = tuple(User.REQUIRED_FIELDS) + (
            User.USERNAME_FIELD,
            'image',
            'password',
        )

    def create(self, validated_data):
        if settings.get('SEND_ACTIVATION_EMAIL'):
            with transaction.atomic():
                user = User.objects.create_user(**validated_data)
                user.is_active = False
                user.save(update_fields=['is_active'])
        else:
            user = User.objects.create_user(**validated_data)
        return user

我的注册视图：

class RegistrationView(generics.CreateAPIView):
    serializer_class = serializers.UserRegistrationSerializer
    permission_classes = (
        permissions.AllowAny,
    )

    def perform_create(self, serializer):
        user = serializer.save()
        signals.user_registered.send(sender=self.__class__, user=user, request=self.request)
        if settings.get('SEND_ACTIVATION_EMAIL'):
            self.send_activation_email(user)
        elif settings.get('SEND_CONFIRMATION_EMAIL'):
            self.send_confirmation_email(user)

这会创建一个新用户。但是，当我尝试使用已经注册的电子邮件点击此端点时，我收到错误消息。而不是这个，我想更新用户条目，以防用户不活动并想再次注册。我无法弄清楚这一点。我尝试在序列化程序中使用update（）方法，但它没有用。请帮忙。

Answer 1

我会在序列化程序的public class CustomTextAreaTest extends Application { public void start(Stage primaryStage){ AnchorPane pane = new AnchorPane(); CustomTextArea area = new CustomTextArea(); area.setText("Custom text area test"); area.setLayoutX(10); area.setLayoutY(10); pane.getChildren().add(area); Scene scene = new Scene(pane); primaryStage.setScene(scene); primaryStage.sizeToScene(); primaryStage.show(); } public static void main(String[] args){ launch(args); } }方法中执行此操作。

create

创建新的自定义用户或更新现有用户
