Creating Complex ActiveResource objects

Rails
1

Given the following models:

class Uptime < ActiveRecord::Base
has_many :pings
end

class Ping < ActiveRecord::Base
belongs_to :uptime
end

I can create an ActiveResource that will get the uptimes and ping
models:

class UptimeResource < ActiveResource::Base
self.site = “http://localhost:3000”
self.element_name = “uptime”
end

class PingResource < UptimeResource
self.element_name = “ping”
end

If the information exists in the database, I can do
UptimeResource.find(1).pings and get a list of pings. But how can I
create pings besides creating an UptimeResource and then creating the
pings separately. I am trying to save the XML into an XML Database and
bypass a relational database (client requirements). I wish I had
something like CouchDB_fu but for XML databases…

Is this a job for DataMapper? I am open to any strategy. Swift kicks
to the head welcome.

Yes you would normally update pings as they occur, unless your
thinking of submitting
a xml and doing a bulk update. So the “pinger” is doing a butch of
pings, then
sending the results to the backend?
Then you just need to convert a local array to a xml file and submit
it to your Restful web app.

The “convert a local array to xml” is where I am running into issues.
I keep trying to set a “pings” property but it isn’t working. How do I
shove that into the Uptime object so that they are all transmitted at
the same time?
