A Django application for building WebDAV services.
Installation and Configuration
Just add 'davvy' in
INSTALLED_APPS and set the directory where you want to store WebDAV files via the
DAVVY_STORAGE_PATH settings option:
DAVVY_STORAGE_PATH = '/var/www/davvy'
Now you can start configuring your application's urls. Davvy is class-view based, so you can extend it by simply subclassing the WebDAV class (as an example the included CardDAV and CalDAV classes inherit from it).
The url regexp must obey to a simple rule:
from davvy.base import WebDAV from davvy.addressbook import CardDAV from davvy.calendar import CalDAV urlpatterns = patterns('', url(r'^principals/(\w+)/(.*)', WebDAV.as_view(root='storage')), url(r'^storage/(\w+)/(.*)', WebDAV.as_view(root='storage')), url(r'^addressbook/(\w+)/(.*)', CardDAV.as_view(root='addressbook001')), url(r'^calendars/(\w+)/(.*)', CalDAV.as_view(root='calendars')), url(r'^admin/', include(admin.site.urls)), )
As you can see, the second part of the url must always be catched, as it contains the username owning the resource you want to use.
/principals/foobar/ will be the base for the 'foobar' user, as well as
/principals/foobar/photos/2014/summer/1.jpg will map to the /photos/2014/summer/1.jpg resource for the 'foobar' user.
/addressbook/foobar is instead the main storage for the CardDAV system (all of the collections will be automatically mapped to an addressbook resource).
root parameter in the class-based-view arguments is required, and you can see it as the 'disk' containing collections and objects.
/principals/foobar/photos/2014/summer/1.jpg will be indeed mapped to
storage/photos/2014/summer/1.jpg of the user
The root directory is created for every user on-demand.
Davvy specific features
Protected resources won't be deleted by any of the client requests. You can mark protected resources by using, for instance, the Django Admin Interface.
Resources can be shared among users. Specifically, you can assign resources to one or more groups. Then, those resources will be shared among every user belonging to the selected groups.
As an example, you could share one of your calendars with the group "bars". To do so, you only need to select "bars" among the groups of your calendar, in the Django admin interface, or anywhere else. That's it, refresh your client and voilà!
Home sets autodiscovery (required for iOS/OSX clients)
Moderns Dav clients automatically try to discover the home of specific resources.
As an example a CardDAV client could get the home of a principal (see it as a username in Dav slang) addressbook, asking for the
addressbook-home-set property (with a PROPFIND request).
Davvy can be configured to return such path via Django settings.py:
DAVVY_CURRENT_USER_PRINCIPAL_BASE = '/principals' DAVVY_ADDRESSBOOK_HOME_SET_BASE = '/addressbook' DAVVY_CALENDAR_HOME_SET_BASE = '/calendars'
Remember: davvy will automatically append /username to every home.
Thanks to this options you will be able to force your client to search for calendars in /calendars/foobar even if it has been configured for /principals/foobar.
Furthermore, Apple clients will sporadically send PROPFIND requests to your server root.
As a consequence, and in order to avoid unpleasant 404 errors, you could add to your
urlpatterns the following lines:
from davvy.wellknown import WellKnownDAV urlpatterns = patterns('', # ... url(r'^$', WellKnownDAV.as_view(root='storage')), # ... )
Apple's custom autodiscovery
As a consequence, you'll be able to configure your client by only entering the server remote address, without caring about any of the home sets.
Davvy can be configured to correctly return the required protocol components to any Apple client by simply editing your
urlpatterns as follows:
from davvy.wellknown import WellKnownDAV urlpatterns = patterns('', # ... url(r'^.well[-_]?known/caldav/?$', WellKnownDAV.as_view(root='calendars')), url(r'^.well[-_]?known/carddav/?$', WellKnownDAV.as_view(root='addressbook001')), # ... )
Client-side configuration largely varies.
As an example, we provide here some configuration samples to be used in OS X Mavericks (10.9) Calendar/Contacts and in Mozilla Thunderbird.
OS X Calendar
If you have enabled davvy's autodiscovery for Apple clients you can simply setup a CalDAV account as follows:
Account Type = Manual User Name = foo Password = bar Server Address = www.yourserver.org
Otherwise, you should use the following configuration:
Account Type = Advanced User Name = foo Password = bar Server Address = www.yourserver.org Server Path = /calendars/foo Port = 8080 ; or any port you want
OS X Contacts
If you have enabled davvy's autodiscovery for Apple clients you can simply setup a CardDAV account as follows:
Account Type = CardDAV User Name = foo Password = bar Server Address = www.foo.org
Otherwise, your server address path should point to the specific user's addressbook:
Note: the trailing slash in the server address is mandatory when running in HTTPS mode.
Mozilla Thunderbird does not provide WebDAV support out-of-the-box, but provides service specific extensions.
As a consequence, to manage your CalDAV calendars you'll need to install the Lightning extension.
Then, you can add a new "on the network" CalDAV calendar.
Lightning does not provide any form of service discovery. So, you'll need to enter the full calendar path in the location field: i.e.:
This project makes use of the litmus tool for testing.
