Django Media

Warning

Don’t forget to use <form enctype="multipart/form-data" method="post"... in your forms, or the file/image will not be uploaded.

Public

To set-up your site for user upload of media with public access:

In your settings/base.py file:

MEDIA_URL = '/media/'

In your settings/local.py file:

MEDIA_ROOT = 'media'

In your settings/production.py file:

MEDIA_ROOT = get_env_variable("MEDIA_ROOT")

The Salt state will set-up your site so media root is pointing to a folder which is accessible to the public.

For development, add the following to your project/urls.py file:

from django.conf import settings
from django.conf.urls.static import static

urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
#   ^ helper function to return a URL pattern for serving files in debug mode.
# https://docs.djangoproject.com/en/1.5/howto/static-files/#serving-files-uploaded-by-a-user

The static method will only be active when DEBUG is False.

Private

For private uploads/attachments we use https://django-sendfile2.readthedocs.io/en/latest/

Add django-sendfile2 to your base.txt requirements:

django-sendfile2

Tip

See Requirements for the current version.

The production.py settings file should contain the following:

FILE_UPLOAD_PERMISSIONS = 0o644

SENDFILE_BACKEND = 'sendfile.backends.nginx'
SENDFILE_ROOT = get_env_variable("SENDFILE_ROOT")
SENDFILE_URL = '/private'

Tip

For more details on the FILE_UPLOAD_PERMISSIONS setting, see failed (13: Permission denied) using sendfile.

private_file_store

In your base application, create a store for private files:

private_file_store = FileSystemStorage(location=settings.SENDFILE_ROOT)

Any models with a file field where the download needs to be kept private should use the private_file_store e.g:

pdf = models.FileField(
    upload_to='invoice/%Y/%m/%d',
    storage=private_file_store,
)

Tip

After creating the migration, update the location parameter as follows, FileSystemStorage

Development

For development, add the following to your local.py settings file:

SENDFILE_BACKEND = 'sendfile.backends.development'
SENDFILE_ROOT = 'media-private'

The upload should just work. For the download, you might like to try something like this:

# views.py
@login_required
def download_cv(request, pk):
    """https://github.com/johnsensible/django-sendfile"""
    if not request.user.is_staff:
        raise PermissionDenied()
    enrol = get_object_or_404(Enrol, pk=pk)
    return sendfile(
        request,
        enrol.cv.path,
        attachment=True,
        # attachment_filename='{}.pdf'.format(enrol.pk)
    )

# urls.py
url(regex=r'^cv/(?P<pk>\d+)/$',
    view=download_cv,
    name='enrol.download.cv'
    ),

<a href="{% url 'enrol.download.cv' object.pk %}">
  <i class="fa fa-download"></i>
  CV
</a>
