使用Heroku的Django部署,django,heroku,Django,Heroku,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，以适合我的项目。让我们快速回顾一下我到目前为止所做的工作：在my virtualenv中安装了django工具带在名为Procile的项目根目录中创建了一个profile，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使用pipfreeze创建requirements.txt，并将其放置在我的项

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，以适合我的项目。让我们快速回顾一下我到目前为止所做的工作：

在my virtualenv中安装了django工具带
在名为
```
Procile
```
的项目根目录中创建了一个profile，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
使用
```
pipfreeze
```
创建
```
requirements.txt
```
，并将其放置在我的项目根目录中

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 remote，并将我的项目推送到heroku。成功了
```
heroku ps:scale web=1
```

然而，当我试图访问我的项目时，我得到一个

应用程序错误

。当我用heroku

heroku ps--app projectname

检查状态时，显示dyno已经崩溃。重新启动没有任何作用

heroku日志--app projectname产生：

如果您有任何帮助/建议，我将不胜感激，我无法就此直接与heroku联系，这里的一切都是指您。

嗯，不太确定。尽管heroku的文档推荐了您尝试过的方法。我真的不知道gunicorn在heroku的何处安装，以及它是如何导入django项目的。使用django设置访问进程/服务器的更可能的方式似乎是

web:bin/gunicorn\u django--workers=4--bind=0.0.0:$PORT-django\u-project/settings.py

根据此处的建议：

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，保持原样，撤换

我也跟着他们的演练，遇到了同样的问题。对我来说，是DATABASES语句出错了。我用他们提供的数据库配置替换了我的数据库配置，而它必须添加到数据库设置已经创建的字典中。因此，与其替换数据库语句，不如添加：

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

Heroku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.
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。我遇到了它，它解释了它是如何发生的，并展示了如何覆盖构建包。对于本例，我们将指定Python构建包，但您可以指示Heroku将构建包用于您正在构建的任何类型的应用程序（）

我用过：

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

这个表单可以在本地和heroku上使用

谢谢，但是这并没有详细说明我的数据库设置会发生什么。您可以使用类似于ATABASES={'default'：dj_database\u url.config（default='postgres://settings_stuff')} . 此外，您还应检查以了解连接到db的情况

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