python - Django Migration InternalError 1054 未知列

Question

我在models.py中的现有项目中添加了一个ImageField，我运行了makeMigrations和Migrate，但是现在如果我转到我的管理面板，我会收到以下错误：

InternalError(1054, u"Unknown column 'activelisting.picture' in 'field list'")

如果我删除该 ImageField，此错误就会消失。

我正在运行 Django==1.11.26

这是该字段的副本：

picture = models.ImageField(null=True, blank=True, upload_to='images/')

非常感谢对此的任何帮助。

编辑：之前应该提到过这一点，但它在 MariaDB 上运行。
