用Heroku部署Django

我试图用heroku部署我现有的django项目，遵循heroku提供的步骤，并根据需要进行调整以适合我的项目。只是为了通过什么我迄今所做的快速运行：用Heroku部署Django

安装Django的工具区在我的virtualenv
在我的项目的命名Procile根，其中包括创造了一个Procfile：
```
web: gunicorn projectname.wsgi 
```
使用foreman start确认我的项目仍在本地正常运行
创建requirements.txt使用pip freeze并把它放在我的项目

根添加以下到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'), 
)

这是一个地步，我有点糊涂，演练没有提及发生了什么与我现有的数据库设置，保持原样，删除，更改？

添加以下到wsgi.py：

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

application = Cling(get_wsgi_application())

添加的Heroku作为远程Git推我的项目的Heroku。有效。
heroku ps:scale web=1

然而，当我尝试访问我的项目，我得到一个Application Error。当我检查与英雄heroku ps --app projectname状态它说，测功机已经崩溃。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的Heroku在此联系，这里的一切是指你左右。

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。在过程中更容易的方式/ Django的设置服务器似乎是

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

谢谢，但是，并没有详细说明我的数据库设置会发生什么。 – apardes

那么你可以使用这样的事情ATABASES = {'default'：dj_database_url.config（default ='postgres：// settings_stuff'）}。你也应该检查https://devcenter.heroku.com/articles/heroku-postgresql#connection-in-python以了解连接到数据库 – dusual

这一个地步，我有点糊涂了，演练再没提什么我现有数据库的设置情况，保留原样，删除，更改？

我也跟着他们的漫游，并有同样的问题。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.

这对我跳了出来，因为我正在构建一个Python/Django应用程序。我遇到了this Stackoverflow thread，它解释了它会如何发生，并说明如何覆盖构建包。在这个例子中，我们将指定的Python buildpack但是你可以命令Heroku的使用我用buildpack不管是什么类型的应用程序，你正在构建（click here for a full list）

：

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

这种形式可以在本地和英雄使用
