Question

我收到了这个错误;

ProgrammingError at /
column main_category.parent_cat_id does not exist
LINE 1: ...n_category"."author_id", "main_category"."image", "main_cate. and I believe this means parent_cat_id isn't in the database.

这是我不明白的，我将其设置为null=true和blank=true ....这在本地开发服务器中有效。错误只发生在生产中。（我正在使用弹性豆秆）

class Category(models.Model): 
    name = models.CharField(max_length=128, unique=True)
    author = models.ForeignKey(settings.AUTH_USER_MODEL)

    parent_cat = models.ForeignKey('self', null=True, blank=True)
    hotCat = models.BooleanField(default=False)
    active = models.BooleanField(default=True)

    sponsored = models.ForeignKey(Sponsored, null=True, blank=True)


    objects = CategoryManager()

    def __unicode__(self): 
        return self.name

    def get_absolute_url(self):
        return "/category/%s/" %self.name

    def get_image_url(self):
        return "%s%s" %(settings.MEDIA_URL, self.image)

编辑：

这是我的python配置文件，你可以看到我已经迁移了

我的迁移文件

        ],
    ),

manage.py migrate未在生产中激活...列X不存在......为什么？
