Django 1.7.1 makemigrations 无法识别应用程序

Question

我有以下 Django 应用程序结构：

projectname
    backend
        puzzle
            migrations
                ...
            models
                database.py
                ...
        user
            migrations
                ...
            models
                database.py
                ...

两个应用程序都在项目设置文件中注册：

INSTALLED_APPS = (
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'backend.puzzle',
    'backend.user',
 )

puzzle.models.database.py 包含一个 Django 模型：

from django.db import models


class Puzzle(models.Model):
    title = models.CharField(max_length=50)

也是user.models.database.py:

from django.db import models


class User(models.Model):
    name = models.CharField(max_length=50)

尝试对所有应用程序进行初始迁移会忽略 'user' 应用程序：

> python manage.py migrate
Operations to perform:
  Apply all migrations: admin, contenttypes, puzzle, auth, sessions
Running migrations:
  Applying contenttypes.0001_initial... OK
  Applying auth.0001_initial... OK
  Applying admin.0001_initial... OK
  Applying puzzle.0001_initial... OK
  Applying sessions.0001_initial... OK

正在尝试显式迁移应用程序：

> python manage.py makemigrations user
No changes detected in app 'user'

将 'managed' 用户模型 class 元选项设置为 True 也无济于事。

如何让 Django 识别用户应用程序迁移？

我怀疑你忘记在 user/models/__init__.py 中导入 database:

from user.models.database import *
