Question

我正在尝试使用heroku部署我现有的django项目，跟随heroku提供的步骤并根据需要调整以适应我的项目。只是为了快速完成我到目前为止所做的事情：

在我的virtualenv中安装了django-toolbelt
在名为Procile的项目的根目录中创建了一个Procfile，其中包括：
```
web: gunicorn projectname.wsgi
```
使用foreman start确认我的项目仍在本地正常运行
使用requirements.txt创建pip freeze并将其放在项目的根目录中

将以下内容添加到settings.py：

import dj_database_url
DATABASES['default'] =  dj_database_url.config()

# Honor the 'X-Forwarded-Proto' header for request.is_secure()
SECURE_PROXY_SSL_HEADER = ('HTTP_X_FORWARDED_PROTO', 'https')

# Allow all host headers
ALLOWED_HOSTS = ['*']

# Static asset configuration
import os
BASE_DIR = os.path.dirname(os.path.abspath(__file__))
STATIC_ROOT = 'staticfiles'
STATIC_URL = '/static/'

 STATICFILES_DIRS = (
 os.path.join(BASE_DIR, 'static'),
)

这是我有点困惑的一点，演练没有提到我现有的数据库设置会发生什么，保持原样，删除，更改？

在wsgi.py中添加了以下内容：

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

application = Cling(get_wsgi_application())

将heroku添加为git远程并将我的项目推送到heroku。它奏效了。
heroku ps:scale web=1

但是，当我尝试访问我的项目时，我得到Application Error。当我用heroku heroku ps --app projectname检查状态时，它说dyno已经崩溃了。重启没有任何作用。

heroku logs --app projectname收益：

任何帮助/建议将不胜感激，我发现没有办法直接联系heroku，所有内容都指的是你。

Answer 1

这是我有点困惑的一点，演练没有提到我现有的数据库设置会发生什么，保持原样，删除，更改？

我也跟着他们的演练并遇到了同样的问题。对我来说，是DATABASES语句导致错误。我用他们提供的数据库配置替换了我的数据库配置，而它必须添加到已经由数据库设置创建的字典中。因此，不要替换数据库语句，只需添加：

DATABASES['default'] =  dj_database_url.config()

Answer 2

Heroku有可能在构建过程中识别出错误的应用程序类型。这发生在我身上：

(venv)josephs-mbp:myproject josephfusaro$ git push heroku master
Fetching repository, done.
Counting objects: 27, done.
Delta compression using up to 4 threads.
Compressing objects: 100% (13/13), done.
Writing objects: 100% (14/14), 1.26 KiB | 0 bytes/s, done.
Total 14 (delta 9), reused 0 (delta 0)

-----> Node.js app detected

这让我跳了起来，因为我正在构建一个Python / Django应用程序。我遇到了this Stackoverflow thread，它解释了它是如何发生的，并展示了如何覆盖构建包。对于此示例，我们将指定Python buildpack，但您可以指示Heroku将buildpack用于您正在构建的任何类型的应用程序（click here for a full list）

heroku config:set BUILDPACK_URL=https://github.com/heroku/heroku-buildpack-python

Answer 3

不太确定。虽然heroku的文档建议你尝试的方式。我真的不确定在heroku中安装了gunicorn以及它是如何导入django项目的。使用django设置的进程/服务器的可能性似乎是

web：bin / gunicorn_django --workers = 4 --bind = 0.0.0.0：$ PORT django_project / settings.py

如此推荐： http://blog.abhiomkar.in/2011/09/17/deploying-django-on-heroku-mac-os-x/

Answer 4

我用过：

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

此表单可以在本地和heroku上使用

使用Heroku进行Django部署
