Question

这真的很奇怪，我试图将日期时间字段添加到我的事件模型中，并且我一直收到此错误。

事件模型看起来像这样（在妈妈那里）

class Event(models.Model):
    name = models.ForeignKey(Name)
    event_name = models.CharField(max_length=200)
    event_description = models.CharField(max_length=200)
    event_venue = models.CharField(max_length=200)
    event_photoLink = models.CharField(max_length=200)
    event_fbLink = models.CharField(max_length=200)

即使我取出之前的日期时间字段，此错误仍然存在。我可以＆＃34; makemigrations＆＃34;但它未能完成＆＃34;迁移＆＃34;。

奇怪的是，当我启动服务器时会反映出这些变化：/

我试过刷新数据库。我认为错误是因为我提供了错误的类型，但我不知道在哪里（此代码在我将其更改为日期/时间之前工作正常）

关于Django 1.8
