Django 1.7 makemigrations 没有效果

Question

我一直在我的heroku服务器上运行python manage.py makemigrations，但无论我运行多少次，我都会得到:

$heroku run python manage.py makemigrations
Running `python manage.py makemigrations` attached to terminal... up, run.2680
Migrations for 'default':
  0002_auto_20141120_2007.py:
    - Alter field user on usersocialauth

如果我运行heroku run python manage.py migrate

它返回:

Running `python manage.py migrate` attached to terminal... up, run.1285
Operations to perform:
  Synchronize unmigrated apps: baflist_core, rest_framework, localflavor, storages
  Apply all migrations: admin, userAccount, contenttypes, sessions, default, location, messaging, forum, auth, posts
Synchronizing apps without migrations:
  Creating tables...
  Installing custom SQL...
  Installing indexes...
Running migrations:
  No migrations to apply.
  Your models have changes that are not yet reflected in a migration, and so won't be applied.
  Run 'manage.py makemigrations' to make new migrations, and then re-run 'manage.py migrate' to apply them.

诚然，我对 postgres 和迁移的了解只够危险的，所以我想我应该在这里问。有人遇到过这个吗？

Answer 1

本地迁移完成后，您应该在 <your django app>/migrations 上拥有迁移文件文件夹 Ex(restapi 是我的 django 应用程序):

/Django/app/folder/restapi/migrations$ ls
0001_initial.py  0001_initial.pyc  __init__.py  __init__.pyc

所以你应该手动提交迁移文件:

heroku$ git commit restapi/migrations/0001_initial.py -m "migrations file"
heroku$ git push heroku master

注意:Heroku 不会在您的应用程序上自动运行迁移!我已经检查过了!推送文件后，您应该为您的应用程序运行 migrate:

heroku$ heroku run python manage.py migraterestapi运行python manage.py migrate restapi连接到终端...启动，运行.4602要执行的操作: 应用所有迁移:restapi运行迁移: 正在应用restapi.0001_initial...好的
