我将服务器 settings.py 从更改Debug = TrueDebug = False.

我可以httpResponses从我的其他应用程序网址获取,但我无法专门访问 /admin 网址,我收到服务器错误 (500)

我试图改变ALLOWED_HOSTS = ['my-app-name.herokuapp.com','*']这个问题的其他主题所说的,但在我的情况下它对我没有帮助。

(仅针对这个问题添加了“*”并表明我尝试过它并没有解决问题)

当我查看您的日志时,我提出了一个可能是您的问题的建议。

加载管理页面时,Django 使用它自己的静态文件,以便使用适当的 HTML/JS/CSS 向您展示您所看到的网站作为模型的管理页面。

所有这些文件都来自 Django 库。当您说您没有调试服务器时(DEBUG=FALSE),Django 想要加载项目运行环境中的所有资产(HTML、JS、CSS 文件)而不是库本身。他这样做是因为他取决于开发人员调用 collectstatic 命令,该命令需要正确且有效的静态文件配置。


顺便说一句,当我说正确的配置时,我的意思是存在的目录和路径。


此外,如果加载静态文件(如 jQuery、Bootstrap 等文件)的配置错误,则无法加载它们……

我从配置和其他评论中看到您正在使用 Heroku。当 Heroku当然需要收集所有静态文件(包括 ADMIN 文件......)时,Heroku 默认会自动为您调用collectstatic命令。参考链接 - Heroku - Django 和静态资产

所以到目前为止,我们知道几件事:

  • 不仅我们的文件需要静态文件配置,管理页面也需要静态文件配置
  • 当您在 Heroku 上构建 Django 应用程序时,您会自动执行 collectstatic,但如果配置无效,它将无法正常工作。
  • 在您发布的日志上,我看到您无法访问管理页面的 css 文件,因此对于我所描述的内容来说这是一个红灯..

我有一个很大的猜测,你的静态文件配置是错误的,你从来没有在你的机器上本地调用或检查过 collectstatic 命令。这意味着您正在开发一个 REST api 服务器,可以访问管理页面来监控您的数据库......当您以这种方式使用 Django 而不是开发网站时,通常会发生这种情况。

我并不是暗示用 Django 或任何东西开发 REST api 是错误的,我只是想让一切都清楚

尝试将此代码片段用于您的静态文件配置:

PROJECT_ROOT = os.path.dirname(os.path.abspath(_file_))

STATIC_ROOT = os.path.join(PROJECT_ROOT, 'staticfiles')
STATIC_URL = '/static/'

# Extra places for collectstatic to find static files.
STATICFILES_DIRS = (
    os.path.join(PROJECT_ROOT, 'static'),
)

我希望这个答案对你有用,请告诉它是否有用。

指定ADMINS设置,以便您在生产模式下收到有关 500 错误的电子邮件:

ADMINS = (
    ('Your name', 'your@email.com'),
)

文档:https ://docs.djangoproject.com/en/1.10/ref/settings/#admins 还要确保EMAIL_HOST,EMAIL_HOST_USEREMAIL_HOST_PASSWORD已设置。

您还应该在 Heroku 上的应用程序日志中看到真正的错误。

此问题似乎与静态资产的访问有关。

似乎发布了类似的问题: Django staticfiles not found on Heroku (with whitenoise)

这个问题似乎可以通过更改静态资产的配置来解决。

也遇到了这个问题,但解决方案在于静态位置的 nginx 配置。应该

location /static/ {
    root /var/www/fancy-project/;
}

代替

location /static/ {
    root /var/www/fancy-project/static/;
}

也许这对某人有用
