几个月来,我一直在努力在Heroku上部署我的第一个Django站点。我用git push heroku master
成功地构建了站点,用heroku run python manage.py collectstatic --noinput
成功地收集了静态文件。但是当DEBUG = config('DEBUG', default=False, cast=bool)
时,我无法让站点在没有错误500的情况下运行。当DEBUG设置为True时,站点可以运行(虽然我必须弄清楚如何让数据库工作)。我认为我的允许主机设置正确。我在SO上找到的所有答案都不能完全解决我的问题。
我从this answer添加了日志记录,这给了我更多的日志信息,但我不明白为什么静态文件不可用,当我能够成功地收集它们?

我显然错过了很多,任何指导将是最感激的。

您很可能已经解决了问题,但这是为将来遇到问题的其他人准备的。
大多数网站和人们说你需要在
settings.py
中更新ALLOWED_HOSTS
,如下所示:['www.beta800.net', '127.0.0.1']
(或['*']
,用于快速测试,不用于生产)。对我来说,这并没有解决问题,尽管无论如何更新
ALLOWED_HOSTS
都很重要。我的问题是我的应用缺少静态文件夹。如果日志记录显示类似以下的错误:UserWarning: No directory at:/app/static/ warnings.warn(u'No directory at: {}'.format(root))
这也是您的应用中的问题。如果是这种情况,请按照以下步骤操作:1.在本地将
settings.py
中的DEBUG
属性更改为True
。1.确保在
settings.py
中设置了以下属性:1.在本地,将名为
static
的文件夹添加到根文件夹。1.在本地运行
python manage.py collectstatic
,这将在应用的根文件夹中创建另一个名为staticfiles
的文件夹。1.现在,您可以将
settings.py
中的DEBUG
属性设置为False
并部署您的应用。xkftehaa2#
您很可能已经解决了这个问题,但是对于未来的用户,您很可能没有将您的staticfiles目录包含在您的repo中,并且您的主机saas不会为您运行它,所以您要么-将您的staticfiles提交到您的repo中;这是不可取的。-创建一个在部署时运行的命令脚本,并在其中包含creatstatic。-如果主机服务有Heroku这样的控制台,您可以在那里运行它。-将您的主机连接到您的本地控制台,并查看他们的文档以了解如何在您的部署环境中运行py命令
