South不仅可以为你完成此迁移，但你需要精明并分阶段进行。以下是分步指南：（此指南假设你是子类
AbstractUser，而不是
AbstractbaseUser）
- 进行切换之前，请确保在包含你的自定义用户模型的应用程序中启用了南方支持（为便于指导，我们将其称为
accounts
和模型User
）。此时，你应该还没有自定义用户模型。
$ ./manage.py schemamigration accounts --initialCreating migrations directory at 'accounts/migrations'...Creating __init__.py in 'accounts/migrations'...Created 0001_initial.py.$ ./manage.py migrate accounts [--fake if you've already syncdb'd this app] Running migrations for accounts: - Migrating forwards to 0001_initial. > accounts:0001_initial - Loading initial data for accounts.
- 在帐户应用中创建一个新的空白用户迁移。
$ ./manage.py schemamigration accounts --empty switch_to_custom_userCreated 0002_switch_to_custom_user.py.
- User在accounts应用程序中创建你的自定义模型，但请确保将其定义为：
class SiteUser(AbstractUser): pass
- 使用以下代码填写空白迁移。
# encoding: utf-8from south.db import dbfrom south.v2 import SchemaMigrationclass Migration(SchemaMigration): def forwards(self, orm): # Fill in the destination name with the table name of your model db.rename_table('auth_user', 'accounts_user') db.rename_table('auth_user_groups', 'accounts_user_groups') db.rename_table('auth_user_user_permissions', 'accounts_user_user_permissions') def backwards(self, orm): db.rename_table('accounts_user', 'auth_user') db.rename_table('accounts_user_groups', 'auth_user_groups') db.rename_table('accounts_user_user_permissions', 'auth_user_user_permissions') models = { ....... } # Leave this alone- 运行迁移
$ ./manage.py migrate accounts - Migrating forwards to 0002_switch_to_custom_user. > accounts:0002_switch_to_custom_user - Loading initial data for accounts.
- 现在对你的用户模型进行任何更改。
# settings.pyAUTH_USER_MODEL = 'accounts.User'# accounts/models.pyclass SiteUser(AbstractUser): site = models.ForeignKey(Site, null=True)
- 为此更改创建并运行迁移
$ ./manage.py schemamigration accounts --auto + Added field site on accounts.UserCreated 0003_auto__add_field_user_site.py.$ ./manage.py migrate accounts - Migrating forwards to 0003_auto__add_field_user_site. > accounts:0003_auto__add_field_user_site - Loading initial data for accounts.
老实说，如果你已经对设置有所了解并且已经使用过South，那么这就像向帐户模块添加以下迁移操作一样简单。
# encoding: utf-8from south.db import dbfrom south.v2 import SchemaMigrationfrom django.db import modelsclass Migration(SchemaMigration): def forwards(self, orm): # Fill in the destination name with the table name of your model db.rename_table('auth_user', 'accounts_user') db.rename_table('auth_user_groups', 'accounts_user_groups') db.rename_table('auth_user_permissions', 'accounts_user_permissions') # == YOUR CUSTOM COLUMNS == db.add_column('accounts_user', 'site_id', models.ForeignKey(orm['sites.Site'], null=True, blank=False))) def backwards(self, orm): db.rename_table('accounts_user', 'auth_user') db.rename_table('accounts_user_groups', 'auth_user_groups') db.rename_table('accounts_user_user_permissions', 'auth_user_user_permissions') # == YOUR CUSTOM COLUMNS == db.remove_column('accounts_user', 'site_id') models = { ....... } # Leave this alone
