Django 应用程序在 Heroku 上崩溃

Question

我正在尝试使用 runserver 将在我的计算机上运行良好的应用程序移植到 Heroku。我是 Django 的新手，之前从未在 Heroku 上部署过应用程序。我不确定我错过了什么。

这是 heroku 错误：

2015-01-18T01:00:20.825543+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path="/"

我的 wsgi 文件如下所示：

import os
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "ssbo.settings")

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

application = Cling(get_wsgi_application())
application = DjangoWhiteNoise(application)

我已经创建了几个设置文件（基础、本地、暂存、生产）。我通过设置 DJANGO_SETTINGS_MODULE="ssbo.settings.staging"

在 heroku 上使用暂存

暂存文件：

DEBUG = True
TEMPLATE_DEBUG = True
WSGI_APPLICATION = 'ssbo.wsgi.application'
SESSION_COOKIE_AGE = 300
SECRET_KEY = get_env_variable("SECRET_KEY")

import dj_database_url
DATABASES = {}
DATABASES['default'] =  dj_database_url.config()

基本设置文件：

STATIC_ROOT = 'staticfiles'
STATIC_URL = '/static/'

STATICFILES_DIRS = (
    os.path.join(BASE_DIR, 'static'),
)

STATICFILES_STORAGE = 'whitenoise.django.GzipManifestStaticFilesStorage'
BASE_DIR = os.path.join(os.path.dirname(__file__), '..')

requirements.txt:

Django==1.7.3
psycopg2==2.5.4
stripe==1.19.0
gunicorn==19.1.1
dj-database-url==0.3.0
whitenoise==1.0.6
dj-static==0.0.6

过程文件：

web: gunicorn ssbo.wsgi

项目结构：

ssbo
  app
    migrations
    static
      app
    templates
      app
    admin.py
    forms.py
    models.py

    settings
      base.py
      local.py
      production.py
      staging.py
    urls.py
    wsgi.py
  manage.py

Answer 1

运行带有 --preload 标志的 gunicorn 服务器揭示了这个问题。 Procfile 的参数不正确。
