不同版本。

Django: 1.8.2

创建一个适用于python3的虚拟环境。

我要打开终端。

在终端上创建一个虚拟环境。

08:20 ~ $ virtualenv --python="python3" env                                                                                          
Running virtualenv with interpreter /usr/bin/python3
Using base prefix '/usr'
New python executable in env/bin/python3
Also creating executable in env/bin/python
Installing setuptools, pip, wheel...done.
08:21 ~ $

激活虚拟环境 virtualenv。

08:21 ~ $ source env/bin/activate                                                                                                    
(env)08:21 ~ $

安装Django。

使用pip install命令安装Django – 用pip install django安装Django。

(env)08:21 ~ $ pip install django 
Collecting django
Installing collected packages: django
Successfully installed django-1.8.2

创建一个项目

使用命令”python manage.py startproject PROJECTNAME”来创建一个名为PROJECTNAME的项目。

(env)08:27 ~ $ django-admin startproject djexample
(env)08:27 ~ $

执行syncdb

切换到已创建项目的目录。

(env)08:34 ~ $ cd djexample/

暂时进行syncdb操作。

(env)08:35 ~/djexample $ python manage.py syncdb
/home/TakesxiSximada/env/lib/python3.4/site-packages/django/core/management/commands/syncdb.py:24: RemovedInDjango19Warning: The sync
db command will be removed in Django 1.9
  warnings.warn("The syncdb command will be removed in Django 1.9", RemovedInDjango19Warning)

You have installed Django's auth system, and don't have any superusers defined.

(env)08:35 ~/djexample $

将其在网络上公开

应用程序的设置

选择要使用的Web框架。
虽然有Django，但选择它将导致使用Python2.7和Django1.6，因此选择手动配置。

选择Python的版本。只能选择Python3.4。

现在，我们已经能够在PythonAnywhere上管理新的djexample。

虚拟环境的配置

按“输入自定义的virtualenv路径”按钮，可以设置使用自己创建的virtualenv。

配置wsgi文件

因为被读取的WSGI文件是固定的，所以我们将替换位于/var/www目录下的WSGI文件。

暂时先备份旧文件。

(env)08:55 ~/djexample $ cp /var/www/takesxisximada_pythonanywhere_com_wsgi.py /var/www/takesxisximada_pythonanywhere_com_wsgi.py.old 
(env)08:55 ~/djexample $

将djexample的wsgi.py原封不动地复制到/var/www目录下，与原文件同名。

(env)08:55 ~/djexample $ cp djexample/wsgi.py /var/www/takesxisximada_pythonanywhere_com_wsgi.py
(env)08:56 ~/djexample $

然后将其改写如下。

"""
WSGI config for djexample project.
It exposes the WSGI callable as a module-level variable named ``application``.
For more information on this file, see
https://docs.djangoproject.com/en/1.8/howto/deployment/wsgi/
"""
import os
import sys
from django.core.wsgi import get_wsgi_application
path = '/home/TakesxiSximada/djexample'
if path not in sys.path:
    sys.path.append(path)

os.environ['DJANGO_SETTINGS_MODULE'] = 'djexample.settings'
application = get_wsgi_application()

实际上，我加入了以下内容。

path = '/home/TakesxiSximada/djexample'
if path not in sys.path:
    sys.path.append(path)

os.environ['DJANGO_SETTINGS_MODULE'] = 'djexample.settings'

添加静态文件的配置

在settings.py中添加STATIC_ROOT。

(env)09:47 ~/djexample $ tail djexample/settings.py 
USE_L10N = True

USE_TZ = True

# Static files (CSS, JavaScript, Images)
# https://docs.djangoproject.com/en/1.8/howto/static-files/
STATIC_URL = '/static/'
STATIC_ROOT = os.path.join(BASE_DIR, 'static')

在urls.py中添加静态文件的配置

(env)09:48 ~/djexample $ cat djexample/urls.py 
from django.conf.urls import include, url
from django.contrib import admin
from django.conf import settings
from django.conf.urls.static import static
urlpatterns = [
    url(r'^admin/', include(admin.site.urls)),
] + static(settings.STATIC_URL, document_root=settings.STATIC_ROOT)

进行collectstatic操作

使用collectstatic命令来收集静态文件。

(env)09:50 ~/djexample $ python manage.py collectstatic                                                                                     
You have requested to collect static files at the destination
location as specified in your settings:
    /home/TakesxiSximada/djexample/static
This will overwrite existing files!
Are you sure you want to do this?
Type 'yes' to continue, or 'no' to cancel: yes
~省略~
(env)09:50 ~/djexample $

访问管理界面

重新启动应用程序

太好了！
