Django南迁移错误
Django南迁移错误
提问于 2012-08-09 19:37:58
我在尝试应用第一个南迁移时遇到错误。我尝试过各种建议(比如删除迁移文件夹中的.pyc文件，转换应用程序并尝试重新启动它，等等)。在座的各位能给我提个建议吗？谢谢

在我的例子中，AttributeError：'module‘对象没有属性'Migration’错误只是在我的迁移文件夹中有一个额外的.py文件。
我在我的迁移目录中有一个额外的实用程序模块，它导致South阻塞。将模块移动到另一个目录(在我的应用程序迁移目录之上)为我解决了这个问题。

可能有点晚了，但还是...您的迁移包中是否有任何其他包(包含__init__.py的文件夹)会干扰结构？

哇。我得到了AttributeError：'module‘对象没有属性’迁移‘错误，原因与上面的答案完全不同。
我有一个缩进错误的迁移文件：
class Migration(SchemaMigration):
def forwards(self, orm):
#
def backwards(self, orm):
#
models = {...}而不是...
class Migration(SchemaMigration):
def forwards(self, orm):
#
def backwards(self, orm):
#
models = {...}我不知道为什么我会有这样的错误，但是当我修复了这个错误之后。
