manage.py 迁移 - 错误
manage.py migration - error
您好,我尝试删除模型、迁移文件并在堆栈中找到一些东西,但我没有找到任何相关信息。
你能帮我解决这个错误吗?
我在 virtualenv
上使用 Django(1.8.8)
来自控制台的错误:

我正在使用 Git 所以我回滚了,但我仍然有这个错误。
您的日志日期字段当前默认分配了一个整数,这应该是一个日期。
migrations.AddField(
model_name='clienthistory',
name='log_date',
field=models.DateTimeField(auto_now_add=True,default=2), # Change to a date
preserve_default=False,
),
也应该可以删除默认设置,因为 auto_now_add
已经这样做了
