django.db.utils.OperationalError: no such column: catalogue_product.is

报错来自django-oscar从低版本向高版本迁移的时候发生的．

完整报错如下:

Traceback (most recent call last):
File "/home/appleyuchi/.virtualenvs/python3.7/lib/python3.7/site-packages/django/db/backends/utils.py", line 84, in _execute
return self.cursor.execute(sql, params)

return Database.Cursor.execute(self, query, params)
sqlite3.OperationalError: no such column: catalogue_product.is_public

The above exception was the direct cause of the following exception:

django.db.utils.OperationalError: no such column: catalogue_product.is_public

解决方案:

稍微复杂，你需要首先定义一个

is_public的字段

然后赋值

然后才能选择NN（not null）

你并不能一开始在新建字段的时候，

就选择NN,DB Browser fro SQLite会报错
