django-downloadview makes it easy to serve files with Django:
Let’s serve a file stored in a FileField of some model:
from django.conf.urls import url, url_patterns
from django_downloadview import ObjectDownloadView
from demoproject.download.models import Document # A model with a FileField
# ObjectDownloadView inherits from django.views.generic.BaseDetailView.
download = ObjectDownloadView.as_view(model=Document, file_field='file')
url_patterns = ('',
url('^download/(?P<slug>[A-Za-z0-9_-]+)/$', download, name='download'),
)
