Django，South和Guardian：迁移 [英] Django, South, and Guardian: Migrate

问题描述

我有两个用户，mh00h1和mh00h2。我也有modelA在我的models.py中定义了以下内容：

  class Meta：
 permissions =（
（'read'，'read'），
（'write'，'write'），
）
  

从shell中，我设置了权限：

 >>> > frhde = create modelA instance 
>>>> assign_perm（'read'，mh00h2，frhde）
 
 DoesNotExist：权限匹配查询不存在。查询参数是{'codename'：u'read'，'content_type'：< ContentType：modelA>} 
  

c code code code code code code code $ c > modelA 并确认了这一点。将读取到 read2 显示 South 没有检测到更改。

  $ /manage.py schemamigration myapp --auto 
 
运行myapp迁移：
  - 没有任何迁移。 
  - 加载myapp的初始数据。 
从0个夹具中安装0个对象
运行监护人的迁移：
  - 没有任何迁移。 
  - 加载监护人的初始数据。 
从0夹具中安装0个对象
  

如何获取原理图迁移要正确更新数据库，还是有更好的方法来做到这一点，不需要重做整个数据库？

谢谢。

解决方案

您可以使用 ./ manage.py syncdb --all ，或创建一个信号， a href =http://devwithpassion.com/felipe/south-django-permissions/ =nofollow>这篇文章。

I have two users, mh00h1 and mh00h2. I also have modelA that defines the following in my models.py:

class Meta:
    permissions = (
        ('read','read'),
        ('write','write'),
    )

From a shell, I went to set permissions:

>>>> frhde = create modelA instance
>>>> assign_perm('read', mh00h2, frhde)

DoesNotExist: Permission matching query does not exist. Lookup parameters were {'codename': u'read', 'content_type': <ContentType: modelA>}

I realized that South didn't migrate my models after I added class Meta to modelA and confirmed this. Changing read to read2 shows that South does not detect the change.

$ /manage.py schemamigration myapp --auto

Running migrations for myapp:
- Nothing to migrate.
 - Loading initial data for myapp.
Installed 0 object(s) from 0 fixture(s)
Running migrations for guardian:
- Nothing to migrate.
 - Loading initial data for guardian.
Installed 0 object(s) from 0 fixture(s)

How can I get schematicmigration to correctly update the database, or is there a better way to do this that does not require redoing the whole database?

Thank you.

解决方案

You can use ./manage.py syncdb --all, or create a signal like in this post.
