Question

我尝试在Django中使用静态文件。当我直接访问文件（通过../static/1.txt）时，它给出了错误404或错误500（取决于我遵循的Stackoverflow回答） Settings.py中的代码如下：

此设置文件有什么问题？为什么我不能访问我的目录“static / mysite”中的静态文件？

这是link to the source code of the app我认为我可能会遗漏一些非常简单的事情......

Answer 1

在您的settings.py中，定义STATIC_和MEDIA_值：

# Absolute filesystem path to the directory that will hold user-uploaded files.
# Example: "/home/media/media.lawrence.com/media/"
MEDIA_ROOT = '/path/to/mydjangosite/media/'

# URL that handles the media served from MEDIA_ROOT. Make sure to use a
# trailing slash.
# Examples: "http://media.lawrence.com/media/", "http://example.com/media/"
MEDIA_URL = 'http://www.mydjangosite.com/media/'

# Absolute path to the directory static files should be collected to.
# Don't put anything in this directory yourself; store your static files
# in apps' "static/" subdirectories and in STATICFILES_DIRS.
# Example: "/home/media/media.lawrence.com/static/"
STATIC_ROOT = '/path/to/mydjangosite/static/'

# URL prefix for static files.
# Example: "http://media.lawrence.com/static/"
STATIC_URL = 'http://www.mydjangosite.com/static/'

另外，请确保配置了正确的STATICFILES_FINDERS：

# List of finder classes that know how to find static files in
# various locations.
STATICFILES_FINDERS = (
    'django.contrib.staticfiles.finders.FileSystemFinder',
    'django.contrib.staticfiles.finders.AppDirectoriesFinder',
#    'django.contrib.staticfiles.finders.DefaultStorageFinder',
)

必须启用AppDirectoriesFinder才能从每个应用中的static/子目录中收集静态文件。此外，请确保您的应用程序包含在INSTALLED_APPS设置中，否则AppDirectoriesFinder将不知道在哪里查找静态文件：

INSTALLED_APPS = (
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.sites',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'django.contrib.humanize',
    # Uncomment the next line to enable the admin:
    'django.contrib.admin',
    # Uncomment the next line to enable admin documentation:
    # 'django.contrib.admindocs',
    # DJANGO SOUTH
    'south',
    # MY APPS
    'my_django_app',
)

然后，要从各种应用程序文件夹（例如my_project / my_app / static）收集静态，您必须调用manage.py命令collectstatic：

python manage.py collectstatic

这会将所有各种应用的静态文件移动到STATIC_ROOT中settings.py指定的文件夹中。

最后，确保您的静态文件夹由Web服务器直接提供，而不是通过Django WSGI应用程序提供。对于Apache2 /etc/apache2/sites-available/my_django_site.conf：

<VirtualHost *:80>
      ServerName www.mydjangosite.com
      ServerAlias mydjangosite.com
      ServerAdmin fake@mydjangosite.com

      DocumentRoot /path/to/mydjangosite
      <Directory /path/to/mydjangosite>
             Options FollowSymLinks
             AllowOverride None
             Order allow,deny
             allow from all
      </Directory>

      Alias /static/ /path/to/mydjangosite/static/
      <Directory /path/to/mydjangosite/static>
              Order allow,deny
              allow from all
      </Directory>

      Alias /media/ /path/to/mydjangosite/media/
      <Directory /path/to/mydjangosite/media>
              Order allow,deny
              allow from all
      </Directory>

      # The following installs the Django WSGI app
      WSGIDaemonProcess www.mydjangosite.com processes=2 threads=15 display-name=%{GROUP}
      WSGIProcessGroup www.mydjangosite.com
      WSGIScriptAlias / /path/to/mydjangosite/wsgi.py

</VirtualHost>

alias'd目录的显式Alias定义和Directory标记将覆盖在更高级别父目录中运行的任何WSGI应用程序。

执行sudo service apache2 restart以加载新的site.conf配置。

在我看来，Django中的静态文件是框架中比较混乱的部分之一。 Django希望您将静态文件放入将在开发期间本地提供的文件夹中，但收集到另一个目录，以及第三方应用程序模块可能正在使用的任何其他静态媒体，因此在生产中运行manage.py collectstatic

这是我使用的目录结构，以及一个帮助函数，使静态文件的生活更轻松......

# A Sample Project structure

/sample_app
    manage.py
    /sample_app

    # this directory is served by the 'staticfiles' app during development
    # as specified by STATICFILES_DIRS for the location of the files
    # and a STATIC_URL of '/static/'
    /static-assets/
        /css
        /js
        /images

    # this directory is where all of the folders and files specified in the
    # STATICFILES_DIRS setting get collected to for deployment. The files
    # will be collected to the directory specified by the STATIC_ROOT setting.
    /static


# settings.py

import os

# a helper function to return absolute paths, using settings.py
# as a starting point. This assumes Django >= 1.4.x
def map_path(directory_name):
    return os.path.join(os.path.dirname(__file__),
        '../' + directory_name).replace('\\', '/')

MEDIA_ROOT = map_path('static/uploads/')
MEDIA_URL = '/static/uploads/'

STATIC_ROOT = map_path('static')
STATIC_URL = '/static/'

STATICFILES_DIRS = (
    map_path('static-assets'),
)

# You can also use map_path for other paths, like templates
TEMPLATE_DIRS = (
    map_path('templates),
)

TEMPLATE_CONTEXT_PROCESSORS = (
    ...
    'django.core.context_processors.request',
    'django.core.context_processors.static'
    ...
)

然后您应该能够在模板中引用静态文件：

<link type="text/css" rel="stylesheet"
    href="{{ STATIC_URL }}css/base.css" media="screen,projection" />

另一个潜在的问题是staticfiles应用程序仅在DEBUG = True

时有效

在Django中访问静态文件时出错404和500
