的Django部署在Openshift錯誤500

Question

我下面這個Django的上Openshift教程部署https://github.com/rancavil/django-openshift-quickstart/wiki/Tutorial-How-create-an-application-with-Django-1.6-on-Openshift

不過，我收到500服務器erorr。這裏是我的代碼：

views.py

# -*- coding: utf-8 -*-

    tables = soup.find_all('table') 
    for table in tables:

     data = [[td.text.strip().encode("utf-8") for td in tr.findAll("td")] for tr in row]

     group6 = final_data[25:30] 
     group7 = final_data[30:35] 
     group8 = final_data[35:40] 

    return render(request, 'Groups.html', {"group1": group1, "group2": group2, "group3": group3, "group4": group4, "group5": group5, 
    "group6": group6, "group7": group7, "group8": group8 }) 

urls.py

from django.conf.urls import patterns, include, url 
from django.contrib import admin 
admin.autodiscover() 

urlpatterns = patterns('', 
    url(r'^admin/', include(admin.site.urls)), 
    url(r'^$', 'views.home', name='home'), 
    url(r'^tvarkarastis/', 'polls.views.results', name='results'), 
    url(r'^lenteles/', 'polls.views.tables', name='results'), 
    url(r'^naujienos/', 'polls.views.news', name='naujienos'), 
) 

在localhost一切正常，但在服務器出現問題。錯誤在哪裏？如果你需要更多信息，請說。

UPDATE：settings.py的

調試部分：

if ON_OPENSHIFT: 
    DEBUG = bool(os.environ.get('DEBUG', False)) 
    if DEBUG: 
     print("WARNING: The DEBUG environment is set to True.") 
else: 
    DEBUG = True 

更新（2）：

我使用的virtualenv和我已經安裝在它beautifulsoup4和其他庫。這裏是我的requirements.txt內容：

Django==1.6 
YourAppName==1.0 
argparse==1.2.1 
beautifulsoup4==4.3.2 
requests==2.3.0 
wsgiref==0.1.2 

儘管如此，我收到此錯誤：

No module named bs4 

Answer 1

由於您遇到了ImportError異常，假設您已經安裝了所有需求，它可能是一個虛擬環境問題。在Openshift上運行時，您應該手動激活它。基本上，根目錄中的wsgi.py可能包含如下內容：

#!/usr/bin/python 
import os 

virtenv = os.path.join(os.environ['OPENSHIFT_PYTHON_DIR'], 'virtenv') 
virtualenv = os.path.join(virtenv, 'bin', 'activate_this.py') 
try: 
    execfile(virtualenv, dict(__file__=virtualenv)) 
except IOError: 
    pass 

from yourproject.wsgi import application 

Answer 2

您可以檢查兩兩件事：

第一，怎麼樣在你ALLOWED_HOSTS設置settings.py？當您正在進行生產時（意味着DEBUG設置爲FALSE），您需要正確設置它，否則您會爲每個請求獲得HTTP 500。 See Django docs here。

第二件事是爲了在生產環境中輕鬆地安裝正確的庫和包，您應該編輯您的setup.py，就像教程中提到的一樣。您的錯誤消息告訴您至少有一個模塊丟失。

已經有一個完整的例子在你tutorial：

# Put here required packages 
packages = ['Django<=1.6',] 

# This is if you like use redis cloud w/Django... 
if 'REDISCLOUD_URL' in os.environ and 'REDISCLOUD_PORT' in os.environ and 
    'REDISCLOUD_PASSWORD' in os.environ: 
    packages.append('django-redis-cache') 
    packages.append('hiredis') 

setup(name='YourAppName',   # <= Put your application name, in this case 'mysite' 
     version='1.0', 
     description='OpenShift App', # <= Put your description if you want 
     author='Your Name',   # <= Your name!!!! 
     author_email='example@example.com', 
     url='https://pypi.python.org/pypi', 
     install_requires=packages, 
) 

它會像這樣推到你的openshift回購後進行處理：

When we make the push, all task are execute automatically for install and configure Django on Openshift. This executes $ python setup.py install on the remote Openshift for us.

Basically the tasks sequence are:

1. Install Django 1.6 and all packages in install_require of the setup.py file.
2. Execute the script deploy (file located in mysite/.openshift/action_hook)
3. And execute the python script secure_db.py (file located in mysite/.openshift/action_hook) to create the password for the admin user.

希望這有助於！
