Hi All

I am curious about the OBS webui communication with the backend api, so I
begin to study ROR for some days. Is there a easy way to understand the
communication between OBS frontend webui and the backend api , just like
some docs about activexml module or for developers?

activexml is basically two things: the HTTP implementation as part of
transport.rb and on top of that is the Node, which is parsing the XML
returned from the API into a ruby tree.

For this to work every API route needs to be mapped to a model and a
route, so you can find in config/initializers/activexml.rb e.g.

map.connect :statusmessage, 'rest:///status/messages/:id/?:limit'

This maps to app/models/statusmessage.rb, so you can use
Statusmessage.find(:id => params[:message_id])

This will then call into $APIURL/status/messages/#{params[:message_id}
and the returned XML is available in the model.

So e.g. see this example:

irb(main):003:0> Statusmessage.find(id: 1).message.msg_id
=> "1"
irb(main):004:0> Statusmessage.find(id: 1).value(:message)
=> "Now we have status messages ... watch out for notes here, if you
encounter problems."
