我正在尝试使用heroku 部署我现有的django 项目，遵循heroku 提供的演练并根据需要进行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

  • 在我的项目的根目录中创建了一个 Procfile，Procile其中包括：

    web: gunicorn projectname.wsgi

  • 使用foreman start确认我的项目仍然在本地正常运行

  • requirements.txt使用创建pip freeze并将其放置在我的项目的根目录中

  • 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。有效。

  • heroku ps:scale web=1

但是，当我尝试访问我的项目时，我得到一个Application Error. 当我用 heroku 检查状态时，heroku ps --app projectname它说测功机已经崩溃。重新启动没有任何作用。

heroku logs --app projectname产量：

任何帮助/建议将不胜感激，我找不到直接联系heroku的方法，这里的一切都指向你。

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，遇到了同样的问题。对我来说，是 DATABASES 语句导致了错误。我用他们提供的配置替换了我的数据库配置，而它必须只添加到您的数据库设置已经创建的字典中。因此，不要替换您的数据库语句，只需添加：

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

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

这让我大吃一惊，因为我正在构建一个 Python/Django 应用程序。我遇到了这个 Stackoverflow 线程，它解释了它是如何发生的，并展示了如何覆盖构建包。对于本示例，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（单击此处查看完整列表）

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

嗯，不太确定。尽管 heroku 的文档推荐了您尝试过的方式。我真的不确定 gunicorn 在 heroku 中的安装位置以及它是如何导入 django 项目的。使用 django 设置的进程/服务器更可能的方式似乎是

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

在这里推荐：http: //blog.abhiomkar.in/2011/09/17/deploying-django-on-heroku-mac-os-x/

我用了：

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

这种形式可以在本地和heroku上使用
