Railsdav (WebDAV for Ruby On Rails)
===================================

Important note: This interim commit is in no way release-quality. It mainly exists in order for me to test that I have git installed correctly! Kieran

Railsdav is a plugin which allows for custom WebDAV controllers to be added to a Ruby On Rails application to expose functionality as filesystems to WebDAV clients such as Mac OS X Finder, Windows Network Places, Dreamweaver etc.

ktopping's enhancements include:
 * Locking - there is a partially complete framework for acquiring/releasing locks, allowing applications to specify their own "Lock Factory" for creating, checking & releasing locks. Two example implementations exist:
    * ActiveRecordLockFactory: Implements locks via an ActiveRecord class. See example class below, "WebdavLock".
    * FileSystemLockFactory: Implements locks via native filesystem locks.
   The locking implementation allows a wider number of clients to connect to the webdav server, and it allows them to perform a greater set of functionality.
 * ActiveRecord webdav implementation. Addition of an "acts_as_active_record_webdav" method which stores resources in a database table of your choice, via an ActiveRecord class of your choice.

Storing resources via ActiveRecord, and implementing locks via ActiveRecord means that this plugin can run on platforms without a writable filesystem. One obvious example being Heroku.

Railsdav requires the following gems in addition to rails

* unicode (gem install unicode)
* shared-mime-info (gem install unicode)
# mimetypes (gem install mime-types)

Railsdav was created by Stuart Eccles (http://www.liverail.net/). I'd like to thank the following people for assisting with Railsdav

*   Albert Ramstedt who contributed bug fixes for a variety of code issues and helped with re-structuring the plugin
*   Alex MacCaw
*   Fabien Franzen

Resource storage model:

 create_table :webdavs do |t|
    t.string   :path
    t.binary   :data
    t.integer  :size, :null => false
    t.boolean  :is_directory, :null => false
    t.timestamps
 end

 add_index :webdavs, [:path], :unique => true

Lock model

 create_table :webdav_locks do |t|
    t.string   :path
    t.string   :token
    t.timestamps
 end
 add_index :webdav_locks, [:path], :unique => true
