你好 stackoverflow 社区，

当我尝试写入我的数据库时，我遇到了这个错误。我似乎无法history_change_reason通过 mysqlWorkbench 在我的数据库中找到列。以前有其他人处理过这个吗？

  File "/opt/anaconda3/envs/py2/lib/python2.7/site-packages/django/db/models/base.py", line 822, in _save_table
    result = self._do_insert(cls._base_manager, using, fields, update_pk, raw)

  File "/opt/anaconda3/envs/py2/lib/python2.7/site-packages/django/db/models/query.py", line 920, in _insert
