settings.py

INSTALLED_APPS = [
    ...
    's3direct',
    ...
]

# AWS keys
AWS_SECRET_ACCESS_KEY = ''

# The region of your bucket, more info:
# http://docs.aws.amazon.com/general/latest/gr/rande.html#s3_region

# Destinations in the following format:
# {destination_key: (path_or_function, auth_test, [allowed_mime_types], permissions, custom_bucket)}
#
# 'destination_key' is the key to use for the 'dest' attribute on your widget or model field
S3DIRECT_DESTINATIONS = {
    # Allow anybody to upload any MIME type
    'misc': ('uploads/misc',),

    # Allow staff users to upload any MIME type
    'files': ('uploads/files', lambda u: u.is_staff,),

    # Allow anybody to upload jpeg's and png's.
    'imgs': ('uploads/imgs', lambda u: True, ['image/jpeg', 'image/png'],),

    # Allow authenticated users to upload mp4's
    'vids': ('uploads/vids', lambda u: u.is_authenticated(), ['video/mp4'],)

    # Allow anybody to upload any MIME type with a custom name function, eg:
    'custom_filename': (lambda original_filename: 'images/unique.jpg',),

    # Specify a non-default bucket for PDFs
    'pdfs': ('/', lambda u: True, ['application/pdf'], None, 'pdf-bucket',),

    # Allow logged in users to upload any type of file and give it a private acl:
    'private': (
        'uploads/vids',
        lambda u: u.is_authenticated(),
        '*',
        'private')
}

urls.py

urlpatterns = patterns('',
    url(r'^s3direct/', include('s3direct.urls')),
)

Run python manage.py collectstatic if required.

Use in Django admin only

models.py

from django.db import models
from s3direct.fields import S3DirectField

class Example(models.Model):
    video = S3DirectField(dest='destination_key_from_settings')

Use the widget in a custom form

forms.py

from django import forms
from s3direct.widgets import S3DirectWidget

class S3DirectUploadForm(forms.Form):
    images = forms.URLField(widget=S3DirectWidget(dest='destination_key_from_settings'))

views.py

from django.views.generic import FormView
from .forms import S3DirectUploadForm

class MyView(FormView):
    template_name = 'form.html'
    form_class = S3DirectUploadForm

templates/form.html

<html>
<head>
    <meta charset="utf-8">
    <title>s3direct</title>
    {{ form.media }}
</head>
<body>
    {{ form.as_p }}
</body>
</html>
