我在 Heroku 中创建了 syncdb（Python/Django 应用程序），他创建了表 south_migrationhistory，

(venv-project)username@username:~/projectapp$ heroku run python manage.py syncdb
Running `python manage.py syncdb` attached to terminal... up, run.5529
Syncing...
Creating tables ...
Creating table auth_permission
Creating table auth_group_permissions
Creating table auth_group
Creating table auth_user_groups
Creating table auth_user_user_permissions
Creating table auth_user
Creating table django_content_type
Creating table django_session
Creating table django_site
Creating table django_admin_log
Creating table south_migrationhistory

(...)

Synced:
 > django.contrib.auth
 > django.contrib.contenttypes
 > django.contrib.sessions
 > django.contrib.sites
 > django.contrib.messages
 > django.contrib.staticfiles
 > django.contrib.admin
 > south

Not synced (use migrations):
 - core
 - galeria
(use ./manage.py migrate to migrate these)

但是当我迁移应用程序时，他说没有创建该表：

(venv-project)username@username:~/projectapp$ heroku run python manage.py migrate core
Running `python manage.py migrate core` attached to terminal... up, run.7542

（......可怕的日志......）

File "/app/.heroku/python/lib/python2.7/site-packages/django/db/backends/sqlite3/base.py", line 337, in execute
    return Database.Cursor.execute(self, query, params)
django.db.utils.DatabaseError: no such table: south_migrationhistory

可以是什么？谢谢。

编辑：解决了，我输入了 settings_local gitignore，从而识别了数据库 postgres heroku。

在 Django 1.9 上测试

设置.py

in_heroku = False
if 'DATABASE_URL' in os.environ:
    in_heroku = True

import dj_database_url
if in_heroku:
    DATABASES = {'default': dj_database_url.config()}
else:
    DATABASES = {
        'default': {
            'ENGINE': 'django.db.backends.sqlite3',
            'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
        }
    }

然后运行：

heroku addons:create heroku-postgresql:hobby-dev
sudo apt-get intall postgresql libpq-dev
pip install dj-database-url psycopg2
pip freeze >requirements.txt
git add .
git commit -m 'msg'
git push heroku master
heroku run python manage.py migrate

local_settings.py

import os

SITE_ROOT = os.path.dirname(__file__)

DEBUG = True
TEMPLATE_DEBUG = DEBUG

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': os.path.join(SITE_ROOT, 'data.sqlite3'),
    }
}

在您的 gitignore 中，添加以下内容：

project_name/local_settings.py
*.sqlite3
