Question

我正在使用南方的Django Web应用程序进行数据库迁移。我对南方很新，还有django。我尝试使用南方的官方教程，但是它失败了，例外： AttributeError：'Options'对象没有属性'index_together'。我像这样运行南方命令：

python manage.py schemamigration southtut --initial

southtut模型是：

class Knight(models.Model):
    name = models.CharField(max_length=100)
    of_the_round_table = models.BooleanField()

我的项目模型是：

class Author(models.Model):
    name = models.CharField(max_length=64)
    authorId = models.CharField(max_length=32)

    def __unicode__(self):
        return self.name

    class Meta:
        db_table="Author"   

class Video(models.Model):
    videoId = models.CharField(max_length=32)
    videoUrl = models.URLField(max_length=200)
    author = models.ForeignKey(Author, null=True, related_name="videos", on_delete=models.SET_NULL)

    class Meta:
        db_table="Video"

class User(models.Model):
    token = models.CharField(max_length=50, null=True)
    favs = models.ManyToManyField(Video, related_name="fans", db_table="VideoUserR")

    class Meta:
        db_table = "User"

我收到的整个错误信息如下：

Answer 1

这是南0.8的错误。只需更新到0.8.1或更新，一切都很好。

Answer 2

看起来这是因为您尝试在模型的Meta部分中使用index_together选项。但是这个选项仅适用于django 1.5+，我猜你是在较新版本的django上运行它。

Answer 3

我将django更新为1.5.1，此错误消失了。我不知道'index_together'是如何出现的，但由于它在django 1.5.1中可用，它可以得到它所需要的。
