django-downloadview makes it easy to serve files with Django:

• you manage files with Django (permissions, filters, generation, ...);
• files are stored somewhere or generated somehow (local filesystem, remote storage, memory...);
• django-downloadview helps you stream the files with very little code;
• django-downloadview helps you improve performances with reverse proxies, via mechanisms such as Nginx's X-Accel or Apache's X-Sendfile.

Let's serve a file stored in a file field 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'),
)
