django.core.exceptions.ImproperlyConfigured: Application labels aren't unique, duplicates: foo

有什么问题，如何解决

推荐答案

问题是，随着Django 1.7中应用程序的更改，应用程序需要有一个唯一的标签。

The problem is that with the changes to apps in Django 1.7, apps are required to have a unique label.

默认情况下，应用程序标签是包名称，因此如果您在这种情况下，我们获得了与您的应用程序模块（ foo ）相同名称的包，您将会遇到此错误。

By default the app label is the package name, so if you've got a package with the same name as one of your app modules (foo in this case), you'll hit this error.

解决方案是覆盖您的应用程序的默认标签，并强制将此配置加载到 __ init __。py 。

The solution is to override the default label for your app, and force this config to be loaded by adding it to __init__.py.

# foo/apps.py

from django.apps import AppConfig

class FooConfig(AppConfig):
    name = 'full.python.path.to.your.app.foo'
    label = 'my.foo'  # <-- this is the important line - change it to anything other than the default, which is the module name ('foo' in this case)

和

# foo/__init__.py

default_app_config = 'full.python.path.to.your.app.foo.apps.FooConfig'
