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

它回来了：

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，所以我想我会在这里问。有没有人遇到过这种情况？

Answer 1

本地迁移完成后，<your django app>/migrations 文件夹 Ex 中应该有迁移文件（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：没有 heroku 不会自动在您的应用程序上运行迁移！我已经检查过了！ 推送文件后，您应该为您的应用运行迁移：

heroku$ heroku run python manage.py migrate restapi 运行python manage.py migrate restapi 附加到终端...向上，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...OK
