与Heroku的Django部署
我试图用heroku部署现有的django项目，然后按照heroku提供的步骤进行部署，并根据需要进行调整以适合我的项目。 只是为了快速完成我迄今为止所做的工作：
在名为Procile项目的根目录下创建了一个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
pip freeze创建requirements.txt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，演练没有提及我现有的数据库设置会发生什么，保持现状，删除，更改？
将以下内容添加到wsgi.py中：
from django.core.wsgi import get_wsgi_application
from dj_static import Cling
application = Cling(get_wsgi_application())
将heroku添加为git remote，并将我的项目推到heroku。 有效。
heroku ps:scale web=1 但是，当我尝试访问我的项目时，出现Application Error 。 当我用heroku heroku ps --app projectname检查状态时，它说heroku ps --app projectname已经崩溃。 重新启动什么也不做。
heroku logs --app projectname产量：

任何帮助/建议将不胜感激，我发现没有办法直接联系heroku，一切都指您在这里。
这是我有点困惑的一点，演练没有提及我现有的数据库设置会发生什么，保持现状，删除，更改？
我也跟着他们的演练，也遇到了同样的问题。 对我来说，这是DATABASES声明造成的错误。 我用他们提供的数据库配置替换了我的数据库配置，但只能将其添加到已由数据库设置创建的字典中。 因此，不要替换你的数据库语句，只需添加：
DATABASES['default'] = dj_database_url.config()
在构建过程中，Heroku有可能确定了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.

-----> Node.js app detected
这跳了出来，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。 在这个例子中，我们将指定Python构建包，但是您可以指示Heroku为您构建的任何类型的应用程序使用构建包（点击此处查看完整列表）
heroku config:set BUILDPACK_URL=https://github.com/heroku/heroku-buildpack-python
那么不太确定。 尽管heroku的文档建议您尝试过。 我真的不确定gunicorn在heroku中的安装位置，以及它如何导入django项目。 使用django设置的流程/服务器更可能的方式似乎是
web：bin / gunicorn_django --workers = 4 --bind = 0.0.0.0：$ PORT django_project / settings.py
