This is a simple module for use with django to make a per user dropbox access simple

Requirements: standard django authentication django sessions enabeled * dropbox python api

easy_install dropbox

To use this dropbox module you have to add the following configuration to your settings.py file

DROPBOX_SETTINGS = { 'app_key' : "insert key", 'app_secret' : "insert secret", 'type' : "app_folder", }

and of course to include it in INSTALLED_APPS

INSTALLED_APPS = ( ..., 'django_dropbox', )

python manage.py syncdb

In your views you can import the dropbox_user_required decorator to mark views that should recive the named parameter dropbox_client ` from django_dropbox.decorator import dropbox_user_required

@dropbox_user_required def myViewFunk(request, ..., dropbox_client): file = ... dropbox_client.put_file(file) `
