1.

首先将settings设置debug=false。

2.

STATICFILES_DIRS = (
    ‘static‘,
    os.path.join(os.path.dirname(__file__),  ‘..‘, ‘static‘),
    # Put strings here, like "/home/html/static" or "C:/www/django/static".
    # Always use forward slashes, even on Windows.
    # Don‘t forget to use absolute paths, not relative paths.
)

3.

STATIC_URL = ‘/static/‘

4.

from django.contrib.staticfiles.urls import staticfiles_urlpatterns
urlpatterns += staticfiles_urlpatterns()

或者

url(r‘^(?P<path>.*)$‘,‘django.views.static.serve‘,{‘document_root‘:settings.STATIC_ROOT}),

5.

将自定义的400.html和500.html放到根模板下。
