Question

我已经完成了用Django制作的网站，并希望将其付诸实施。我找到了Heroku，看到它对我的基本需求是免费的，并希望在那里举办。我的网站使用SQLite而不是PostgreSQL，所以我想知道如何使用它，因为它不支持sqlite。我在Heroku上找到了Django页面的入门，但我没有使用pip或virtualenv来设置它。

我应该采取哪些步骤来启动我的网站？仅供参考我正在使用最新的Django dev分支1.8和Python 3.4.1，它是一个个人网站。

这是我的settings.py文件

您需要一个包含所有依赖项的requirements.txt，因为heroku使用该文件为您提供所需的服务。

将postgreSQL附加组件添加到heroku项目后，heroku会为您生成一个DATABASE_URL环境变量。您可以根据heroku的教程在settings.py中解析它：

# Parse database configuration from $DATABASE_URL
import dj_database_url
DATABASES['default'] =  dj_database_url.config()

教程中还提供了基本的wsgi.py，您可以使用它。

from django.core.wsgi import get_wsgi_application
from dj_static import Cling

application = Cling(get_wsgi_application())

将应用程序提交到本地git存储库并将其推送到heroku远程存储库。如果您在控制台上执行此操作，您将获得有关部署的良好反馈。

基本上你需要遵循getting started tutorial。跳过虚拟环境的东西只会使生成需求文件更复杂，但它是可能的。
