我已经检查了一些其他类似问题的帖子。我把所有的事都做了... 我尝试删除所有迁移，然后再次迁移。我也选择了syncdb选项。
仍然出现此错误：http://prntscr.com/nxuq1d 没有这样的表。
我正在使用Django 2.5.1版本
编辑：重写类别的拼写错误后，几乎发生了相同的错误。 这次它说：没有这样的专栏：blog_category_id-> http://prntscr.com/nxvv4r
这是代码

答案 0 :(得分：1)
在以下几行进行更改：
替换
verbose_name = 'catergory'
verbose_name_plural = 'catergories'
到
verbose_name = 'category'
verbose_name_plural = 'categories'
