在我的特定情况下,是这样的:
./ manage.py makemigrations
。 django_content_type
表。 检查数据库中是否有来自Django表的引用。
my_table-+-django_admin_log
`-auth_permission-+-auth_group_permissions
`-auth_user_user_permissions
在我的情况下,我在 django_admin_log $中没有记录c $ c>,
auth_group_permissions
, auth_user_user_permissions
。
运行 ./ manage.py迁移
。当它询问时:
以下内容类型是陈旧的,需要删除:
myapp | foo
通过外键与这些内容类型相关的任何对象也将被删除
。您确定要删除这些内容类型吗?
如果您不确定,请回答否。
键入是继续,或否取消:
只有在上述三个表中的 foo
表中都没有引用记录的记录时,您才能回答是
。或者,如果丢失对您而言不是问题。
Let's say I have this model:
class Foo(models.Model):
name = models.CharField(max_length=255)
I want to rename it to Bar
. What steps should I take? And how do I deal with The following content types are stale
prompt?
In my particular case it was like so:
./manage.py makemigrations
.django_content_type
table. Deal with them accordingly.Inspect your database for references from Django tables. Most likely that would be:
my_table-+-django_admin_log
`-auth_permission-+-auth_group_permissions
`-auth_user_user_permissions
In my case I had no records in django_admin_log
, auth_group_permissions
, auth_user_user_permissions
.
Run ./manage.py migrate
. When it asks:
The following content types are stale and need to be deleted:
myapp | foo
Any objects related to these content types by a foreign key will also
be deleted. Are you sure you want to delete these content types?
If you're unsure, answer 'no'.
Type 'yes' to continue, or 'no' to cancel:
You can answer yes
only if you have no records referencing records in foo
table in the three tables mentioned above. Or if losing them is not an issue for you.
