Question

我分叉了https://github.com/arneb/django-messages/并将其放入我的仓库中：https://github.com/mike-johnson-jr/django-messages/

在使用该软件包时，出现标题错误。完整回溯：

    from django_messages.models import Message
ImportError: cannot import name 'Message'

这是我的django_messages.models代码：

@python_2_unicode_compatible
class Message(models.Model):
    """
    A private message from user to user
    """
    subject = models.CharField(_("Subject"), max_length=140)
    body = models.TextField(_("Body"))
    sender = models.ForeignKey(AUTH_USER_MODEL, related_name='sent_messages', verbose_name=_(
        "Sender"), on_delete=models.SET_NULL)
    recipient = models.ForeignKey(AUTH_USER_MODEL, related_name='received_messages',
                                  null=True, blank=True, verbose_name=_("Recipient"), on_delete=models.SET_NULL)
    parent_msg = models.ForeignKey('self', related_name='next_messages', null=True,
                                   blank=True, verbose_name=_("Parent message"), on_delete=models.SET_NULL)
    sent_at = models.DateTimeField(_("sent at"), null=True, blank=True)
    read_at = models.DateTimeField(_("read at"), null=True, blank=True)
    replied_at = models.DateTimeField(_("replied at"), null=True, blank=True)
    sender_deleted_at = models.DateTimeField(
        _("Sender deleted at"), null=True, blank=True)
    recipient_deleted_at = models.DateTimeField(
        _("Recipient deleted at"), null=True, blank=True)

    objects = MessageManager()

有人知道怎么了吗？预先感谢您的帮助。

我的django_messages.models。消息代码中有错误，get_absolute_url（）有点奇怪。

ImportError：无法导入名称“消息”-django-messages
