我一直试图在Heroku上设置我的Django应用程序几天,似乎已经用尽我的搜索可用于我的问题,至少据我所知 .
Problem Summary: 我能够将我的应用程序推送到Heroku,它似乎成功运行,因为Heroku确认已部署并且构建成功 . 但是当我尝试 heroku open
我的应用程序时,它返回服务器错误 .
以下是我遇到错误时的操作:
git add -A .
git commit -m "initial commit"
heroku create kronos-punch-clock
git push heroku master
以上似乎工作正常,没有任何错误 . 然后我继续说:
heroku ps:scale web=1
Heroku回复:
缩放dynos ...完成,现在运行web at 1:Free
heroku ps
Heroku回复:
gunicorn kronos_clock.wsgi:application --log-file - (1)web.1:up 2016/07/28 17:42:53 -0400(~20s ago)
然后我跑:
heroku open
唉,我得到了一个: Server Error(500)
消息 .
以下是我运行 heroku logs
的日志:

我也一直在Windows 7上创建这个应用程序,如果有帮助的话 . 除此之外,我认为这是我现在想要添加的所有内容,但如果需要任何其他信息,请告诉我,我会为您发布 .
EDIT AND SOLUTION
好的,我明白了 . 有几个错误,但我会尽可能地解释它们以防万一其他人遇到这些相同的问题 .
首先,我在本地演示我的应用程序并想要解释管理站点 . 打开它时,它会出错,然后我记得我从未真正设置它 . 这是给出服务器错误(500)的原因,因为它在尝试访问管理站点时在本地发出了此错误 . 我很快创建了这个,然后继续下面 .
在我的views.py文件中,我有两个DATABASES的任务 . 因此,似乎存在一些冲突,导致Heroku出现一些错误 . 我的应用程序没有必要在当前用户的实例之外写入/保存数据到数据库 . 然而,这是我改变的:
我评论了这一行:
#DATABASES['default'] = dj_database_url.config()
并将其切换为:
if os.getcwd() == "/app":
DATABASES = {'default': dj_database_url.config(default='postgres://localhost')}
if语句允许应用程序在未通过Heroku服务器运行时仍在本地运行 .
我也有重复的DEBUG分配,尽管两者都设置为False,为了清楚起见,我确实删除了一个,并避免将来的更改冲突 .
在DATABASES更改之后,我还将DEBUG更改回:
DEBUG = True
我推到了Heroku并打开了应用程序,幸运的是得到了一个有用的错误:
TemplateDoesNotExist at / kc_app \ base.html请求方法:GET请求URL:https://krono-punch-clock.herokuapp.com/ Django版本:1.9.8例外类型:TemplateDoesNotExist异常值:kc_app \ base.html异常位置:/app/.heroku/python/lib/python3.5/site-packages/django/template/engine.py在find_template中,第169行Python可执行文件:/app/.heroku / python / bin / python Python版本:3.5.1 Python路径:['/ app','/ app / .heroku / python / bin','/ app / .heroku / python / lib / python3.5 / site- packages / setuptools-23.1.0-py3.5.egg','/ app / .heroku / python / lib / python3.5 / site-package / patch8.1.2-py3.5.egg','/ app ','/ app / .heroku / python / lib / python35.zip','/ app / .heroku / python / lib / python3.5','/ app / .heroku / python / lib / python3.5 / plat -linux','/ app / .heroku / python / lib / python3.5 / lib-dynload','/ app / .heroku / python / lib / python3.5 / site-package']服务器时间:周六,30 2016年7月06:33:46 0000
在进一步阅读回溯后,我注意到这些线条:
模板加载器postmortem Django尝试按以下顺序加载这些模板:使用引擎django:django.template.loaders.app_directories.Loader:/app/.heroku/python/lib/python3.5/site-packages/django/contrib /admin/templates/kc_app\base.html
(来源不存在)django.template.loaders.app_directories.Loader:/app/.heroku/python/lib/python3.5/site-packages/django/contrib/auth/templates/kc_app\base.html(来源确实如此) django.template.loaders.app_directories.Loader:/app/kc_app/templates/kc_app\base.html /python3.5/site-packages/bootstrap3/templates/kc_app\base.html(源不存在)
请注意,以下行(从上面)是我的模板所在的位置:
django.template.loaders.app_directories.Loader:/app/kc_app/templates/kc_app\base.html(来源不存在)
仔细看,你会看到一个反斜杠而不是正斜杠 . 在这里,我知道这与Windows构建在Nix服务器上的Heroku服务器以及我在Windows中本地构建应用程序的区别 . 然后我更改了所有的views.py调用和模板,以在正斜杠上包含正斜杠 .
举些例子:
views.py example
return render(request, 'kc_app\\clock_out.html',
{'kc_form':dict_form,'punch_out':final_out})
改为:
return render(request, 'kc_app/clock_out.html',
{'kc_form':dict_form,'punch_out':final_out})
template example
{%extends“kc_app \ base.html”%}
改为:
{%extends“kc_app / base.html”%}
然后我将修复程序推回到Heroku,并且能够成功地使其在服务器上运行 .
