我在线学习了一个很棒的 django教程,但是我遇到了最终heroku部署的问题.

这是django教程：
http://gettingstartedwithdjango.com/en/lessons/introduction-and-launch/

我遇到的问题是最后一次调用heroku：

heroku python manage.py syncdb

这是我得到的错误：

(blog-venv)vagrant@precise64:/vagrant/projects/microblog$heroku run python manage.py syncdb

有什么想法吗

解决方法

据我所知(git中级知识)如果你忘了将locals.py添加到.gitignore文件并提交它,那么git存储库中仍会有locals.py文件.

您必须从git存储库中删除该文件,因为它包含在以前的提交中.

git rm --cached microblog/settings/local.py

然后将microblog / settings / local.py添加到.gitignore并提交更改.

一旦heroku看到正确的DATABASES设置.然后syncdb工作正常

DATABASES = {'default' : dj_database_url.config() }
