【问题描述】：

我正在开始一个 2 年前有人开始的项目，但我无法弄清楚它运行的 django 版本。制作该项目的人不知道，我不确定猜测和检查是否有效，因为我实际上并不知道该项目是否可以编译。我找到了this 的答案，但它表明该版本是 1.0 之前的版本，我不确定从那里去哪里。除了猜测和检查之外，还有什么好方法可以判断版本是什么？

我的 settings.py 是

import os
PROJECT_PATH = os.path.abspath(os.path.dirname(__file__))

DEBUG = True
TEMPLATE_DEBUG = DEBUG

ADMINS = (
    # ('Your Name', '[e-mail]'),
)

MANAGERS = ADMINS

DATABASE_ENGINE = 'sqlite3'           # 'postgresql_psycopg2', 'postgresql', 'mysql', 'sqlite3' or 'oracle'.
DATABASE_NAME = os.path.join(PROJECT_PATH, 'site.db') # Or path to database file if using sqlite3.
DATABASE_USER = ''             # Not used with sqlite3.
DATABASE_PASSWORD = ''         # Not used with sqlite3.
DATABASE_HOST = ''             # Set to empty string for localhost. Not used with sqlite3.
DATABASE_PORT = ''             # Set to empty string for default. Not used with sqlite3.

# Local time zone for this installation. Choices can be found here:
# http://en.wikipedia.org/wiki/List_of_tz_zones_by_name
# although not all choices may be available on all operating systems.
# If running in a Windows environment this must be set to the same as your
# system time zone.
TIME_ZONE = 'America/Chicago'

# Language code for this installation. All choices can be found here:
# http://www.i18nguy.com/unicode/language-identifiers.html
LANGUAGE_CODE = 'en-us'

SITE_ID = 1

# If you set this to False, Django will make some optimizations so as not
# to load the internationalization machinery.
USE_I18N = True

# Absolute path to the directory that holds media.
# Example: "/home/media/media.lawrence.com/"
MEDIA_ROOT = ''

# URL that handles the media served from MEDIA_ROOT. Make sure to use a
# trailing slash if there is a path component (optional in other cases).
# Examples: "http://media.lawrence.com", "http://example.com/media/"
MEDIA_URL = ''

# URL prefix for admin media -- CSS, javascript and images. Make sure to use a
# trailing slash.
# Examples: "http://foo.com/media/", "/media/".
ADMIN_MEDIA_PREFIX = '/media/admin/'

# Make this unique, and don't share it with anybody.
SECRET_KEY = some gibberish

# List of callables that know how to import templates from various sources.
TEMPLATE_LOADERS = (
    'django.template.loaders.filesystem.load_template_source',
    'django.template.loaders.app_directories.load_template_source',
#     'django.template.loaders.eggs.load_template_source',
)

MIDDLEWARE_CLASSES = (
    'django.middleware.common.CommonMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
)

#ROOT_URLCONF = 'site.urls'
ROOT_URLCONF = 'project.urls'

TEMPLATE_DIRS = (
    # Put strings here, like "/home/html/django_templates" or "C:/www/django/templates".
    # Always use forward slashes, even on Windows.
    # Don't forget to use absolute paths, not relative paths.
)

INSTALLED_APPS = (
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.sites',
    'django.contrib.admin',
    'project.site',
)

TD_COMPACT_MODE = False

我的 manage.py 是

#!/usr/bin/env python
from django.core.management import execute_manager
try:
    import settings # Assumed to be in the same directory.
except ImportError:
    import sys
    sys.stderr.write("Error: Can't find the file 'settings.py' in the directory containing %r. It appears you've customized things.\nYou'll have to run django-admin.py, passing it your settings module.\n(If the file settings.py does indeed exist, it's causing an ImportError somehow.)\n" % __file__)
    sys.exit(1)

if __name__ == "__main__":
    execute_manager(settings)

我的 urls.py 是

from django.conf.urls.defaults import *
from project.site.models import Syndicator, Torrent

torrent = 
    'queryset': Torrent.objects.all(),
    'extra_context': 'syndicators': Syndicator.objects.all(),


torrents = 
    'queryset': Torrent.objects.all().order_by('-pub_date'),
    'paginate_by': 25,
    'allow_empty': True,
    'extra_context': 'syndicators': Syndicator.objects.all(),


urlpatterns = patterns('',
    (r'^$', 'django.views.generic.list_detail.object_list', torrents, 'home-page'),

    (r'^feeds/$', 'django.views.generic.list_detail.object_list', torrents, 'feed-list'),
    (r'^feeds/page(?P<page>[0-9]+)/$', 'django.views.generic.list_detail.object_list', torrents, 'feed-list-page'),
    (r'^feeds/post/(?P<object_id>\d+)/$', 'django.views.generic.list_detail.object_detail', torrent, 'feed-post'),
    (and a lot more patterns),
)

【问题讨论】：

这需要更多信息。显示您的settings.py、manage.py 和urls.py。

看看模型。模型是否在内部定义 Admin 类？

像DATABASE_NAME 这样的约定在 Django 1.4 中被删除了，所以让我们关注 od 1.3 及更低版本。有admin.py 文件吗？ urls.py 文件中定义的 admin.site.urls 模式是什么？

@pancakes 是的，

没有admin.py，并且字符串'admin'在urls.py文件中没有出现

【参考方案1】：

(virtualenv)~$ python

>>> import django
>>> print django.get_version()
'1.4.1'

【讨论】：

这告诉我我的机器运行的是什么版本，而不是项目的版本。

嗯，没有简单的答案。我建议您查看（django 和项目）配置文件 - 在 django 开发过程中发生了很多变化。显示为示例 url、数据库声明等。

【参考方案2】：

我不确定这是否重要。数据库设置暗示 pre-1.2，所以 1.1 应该可以正常工作。 Django 很少破坏向后兼容性（该数据库是一个罕见的例外），因此点版本之间的差异应该不会有太大影响。
