用Heroku部署Django

我試圖用heroku部署我現有的django項目，遵循heroku提供的步驟，並根據需要進行調整以適合我的項目。只是爲了通過什麼我迄今所做的快速運行：用Heroku部署Django

安裝Django的工具區在我的virtualenv
在我的項目的命名Procile根，其中包括創造了一個Procfile：
```
web: gunicorn projectname.wsgi 
```
使用foreman start確認我的項目仍在本地正常運行
創建requirements.txt使用pip freeze並把它放在我的項目

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'), 
)

這是一個地步，我有點糊塗，演練沒有提及發生了什麼與我現有的數據庫設置，保持原樣，刪除，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作爲遠程Git推我的項目的Heroku。有效。
heroku ps:scale web=1

然而，當我嘗試訪問我的項目，我得到一個Application Error。當我檢查與英雄heroku ps --app projectname狀態它說，測功機已經崩潰。重新啓動什麼也不做。

heroku logs --app projectname產量：

任何幫助/建議將不勝感激，我發現沒有辦法直接的Heroku在此聯繫，這裏的一切是指你左右。

那麼不太確定。儘管heroku的文檔建議您嘗試過。我真的不確定gunicorn在heroku中的安裝位置，以及它如何導入django項目。在過程中更容易的方式/ Django的設置服務器似乎是

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

謝謝，但是，並沒有詳細說明我的數據庫設置會發生什麼。 – apardes

那麼你可以使用這樣的事情ATABASES = {'default'：dj_database_url.config（default ='postgres：// settings_stuff'）}。你也應該檢查https://devcenter.heroku.com/articles/heroku-postgresql#connection-in-python以瞭解連接到數據庫 – dusual

這一個地步，我有點糊塗了，演練再沒提什麼我現有數據庫的設置情況，保留原樣，刪除，更改？

我也跟着他們的漫遊，並有同樣的問題。對我來說，這是DATABASES聲明造成的錯誤。我用他們提供的數據庫配置替換了我的數據庫配置，但只能將其添加到已由數據庫設置創建的字典中。因此，不要替換您的數據庫語句，只需添加：

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

Heroku有可能在構建過程中識別了錯誤的應用程序類型。這發生在我身上：

(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

這對我跳了出來，因爲我正在構建一個Python/Django應用程序。我遇到了this Stackoverflow thread，它解釋了它會如何發生，並說明如何覆蓋構建包。在這個例子中，我們將指定的Python buildpack但是你可以命令Heroku的使用我用buildpack不管是什麼類型的應用程序，你正在構建（click here for a full list）

：

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

這種形式可以在本地和英雄使用
