Question

我试图在Heroku上部署一个简单的Django应用程序。

当我尝试同步数据库名为＆＃34;微博＆＃34; Heroku说数据库不存在。

django.db.utils.OperationalError: FATAL:  database "microblog" does not exist

我非常确定数据库确实存在。如果我运行createdb microblog，它表示数据库已经存在。我可以在本地同步它，而python manage.py syncdb没有问题。如果我进入dbshell，它似乎正在工作。

(blog-venv)vagrant@precise64:/vagrant/projects/microblog$ python manage.py dbshell
psql (9.1.14)
Type "help" for help.

microblog=#

我是Django的新手，我按照此处的说明操作：http://gettingstartedwithdjango.com/en/lessons/introduction-and-launch/#toc15

运行Django 1.7。

任何帮助都非常感谢，我已经被困在这里太久了！提前谢谢。

编辑：

这就是我在base.py（设置）中所拥有的

DATABASES = {}
DATABASES['default'] =  dj_database_url.config()
DATABASES['default']['ENGINE'] = 'django.db.backends.postgresql_psycopg2'
DATABASES['default']['NAME'] = 'microblog'

Heroku说我的Django应用程序的数据库不存在，我无法理解为什么
