WebDAV Ruby On Rails Plugin 21
Posted by Stuart Eccles Sun, 25 Jun 2006 17:41:00 GMT
The moment a few of you have been waiting for.
I’m releasing the first version of the RailsDAV plugin. What does RailsDAV do. Well it allows people to create Ruby On Rails controllers which will respond to WebDAV requests and expose functionality as a file-system.
The plugin can be downloaded from
svn.liverail.net/svn/plugins/railsdav
Of course the great thing about WebDAV is that it doesn’t just need to expose a directory on your server but can expose any concept you have in your application. For instance, for a Digital Asset Management System expose a list of tags as directory names, navigate into that directory and see all the images tagged with that word.
I’ll write about using the plugin in just a second, but first a little wording. This is definitely a 0.1 release and still needs work and a lot of testing before being production ready. It is likely to take on a different shape as well. It has many problems under WebBrick but works very very nicely under Mongrel (this is a problem with WebBrick) But release early, release often huh!
The plugin contains a base WebDAV controller and 2 specific implementations. A file-system exposer and an ActiveRecord exposer.
With thanks to Fabien Franzen for his input so far
There is also video of the FileSystem WebDAV Controller and the ActiveRecord WebDAV Controller
FileWebDavController
The file system webdav controller can be used by creating a controller in your app/controllers directory.
class MyStoreController < Railsdav::FileSystem::FileWebDavController
set_max_propfind_depth 1
set_rails_webdav_root "directory_under_rails"
end
And in the routes.rb add
map.connect 'mystore/*path_info', :controller => 'my_store', :action => 'webdav'
The set_rails_webdav_root should specify a directory underneath RAILS_ROOT to expose for read/write operations.
To add some HTTP Basic Authentication security you can do
class MyStoreController < Railsdav::FileSystem::FileWebDavController
set_max_propfind_depth 1
set_rails_webdav_root "directory_under_rails"
before_filter :my_auth
def my_auth()
basic_auth_required {|username, password| session[:user] = User.your_authentication(username,password) }
end
end
Start your server. Mongrel is the best if you have it, if you havn’t try
sudo gem install mongrel cd myrailsapp mongrel_rails start -d
To connect you point your webdav client to localhost:3000/mystore/
This includes the MacOSX Connect To Server and Windows WebPlaces or what ever they call them.
ActiveRecordWebDavController
The active record webdav controller is an example of how you can expose things that are not a filesystem over webdav.
Basically it displays all the ActiveRecord models as directories. Access a directory and all the records are shown as YAML files.
class DbStoreController < Railsdav::ActiveRecord::ActiveRecordWebDavController
set_max_propfind_depth 1
end
And in the routes.rb add
map.connect 'dbstore/*path_info', :controller => 'db_store', :action => 'webdav'

Seems you was in a harry – too many typos in the post:
1. def MyStoreController
is maybe better to be (class, not def, FileWebDavController, not FileSystem….)
class MyStoreController
2. in routes.rb:
:action => ‘webdav’ (not ‘weddav’)
Except that, the plugin is working great, thanks a lot for it.
Thanks for the proof-read ;-) I’ve corrected the post.
Enjoy. There is likely to be a few bugs in the plugin too, it isn’t final yet
Great Stuff! Thank you!
Great release… I had been thinking integrated webdav would be perfect for my project… ;)
I’m getting the following error trying to use the file system exposer.
This was using the 1.15 gem for the required “mime/types” include—is that the right idea?
If you’ve got a chance to point me in the right direction, that’d be most appreciated!
Yes it does require the mime-types gem. I should put that in the documentation.
That is an interesting error, looks like a problem with the properties getter maybe. Can you email me some info on which client you are testing it with and a full stack trace.
thanks stueccles (at) gmail dot com
How do i checkout the plugin? Seems to require a login. svn co svn.liverail.net/svn/plugins/railsdav ?
This looks so promising, but I can’t get it working reliably. I’m curious though, why problems under webrick but okay under mongrel? Is there a Mongrel WebDAV implementation you’re relying on?
No it is not reliant on Mongrel it is entirely built with Ruby on Rails and should work fine in Lighttpd for instance.
The WebBrick problems seem to be related to WebBrick handling PUT requests for large files. This could probably be solved by increasing the the cache size in WebBrick.
Its still a first release and needs work but at the moment I just have zero time.
Is there anything special to get it working with lighttpd?
I got it working pretty well using mongrel in development, but when i switch to lighty, it just hangs when i try to mount a dav resource.
thanks…looks great so far.
Stuart,
You rock. I am excited to be able to use Webdav directly from within Rails apps with your plugin. Thank you!
Stuart – This looks great, thank you for putting this all together. I happened to be looking at Boxroom , any thoughts on how the two of these could play nicely together? Seems like this could be a really cheap/easy way to host a personal Strongspace type site. Is there any way to “intercept” files as they are uploaded/downloaded via WebDAV so that the proper “asset magic” could take place?
Feel free to email or forward me on if that’s easier :)
Cheers, Graham

Yikes…looks like my dropping connection messed up the post. Apologies.
I am getting the error :
Railsdav::WebDavController: missing default helper path railsdav/web_dav_helper Railsdav::FileSystem::FileWebDavController: missing default helper path railsdav/file_system/file_web_dav_helper MyStoreController: missing default helper path my_store_helper
when I launch /mystore with mongrel
Can anyone help? Thanks, Sari
Got it working for downloading a single file. How do you configure things to work with a directory? WIthin the webdav root we created a test directory with a test file. We can pull the file if we put in the full pathname, but how do we display the directory contents.
Thanks, Sari
good
