Using a fork of someone else's code, I added a model field and did the usual auto migration:
使用别人代码的分支，我添加了一个模型字段并进行了通常的自动迁移：
~ $ django_admin.py migrate mezzanine_slides --auto
You cannot use automatic detection, since the previous migration does not have this whole app frozen.
Either make migrations using '--freeze mezzanine_slides' or set 'SOUTH_AUTO_FREEZE_APP = True' in your settings.py.
I tried the obvious options using the hint to no avail, and got nowhere from the documentation.
我尝试使用提示的明显选项无济于事，并且从文档中无处可去。

OK, with some trial and error: I created a 'frozen migration' thus:
好的，经过一些试验和错误：我创建了一个'冻结迁移'，因此：
~ $ django_admin.py schemamigration --freeze mezzanine_slides mezzanine_slides freeze --empty
Created 0002_freeze.py. You must now edit this migration and add the code for each direction.
Then I edited the resulting migration and deleted my added field so that:
然后我编辑了生成的迁移并删除了我添加的字段，以便：
! $ django_admin.py schemamigration mezzanine_slides --auto
+ Added field caption on mezzanine_slides.Slide
Created 0003_auto__add_field_slide_caption.py. You can now apply this migration with: ./manage.py migrate mezzanine_slides
with that done, the migration worked fine.
完成后，迁移工作正常。
