EDGE Rails, Erb Views, Confused

Rails
1

I have been working with rails on and off for a while now. I still
consider myself a noob with rails. Now with EDGE rails I am quite
lost. I am using the Preview Release right now. My database migrations
are quite sexy. I am just having the following trouble.

Right now I have started development of a snmp monitor app which will
just be used for in house, for now.

I want to add another link in the show view called “Walk” which will
run an SNMP walk on the IP that is provided in the box. How would I go
about doing that.
Would the snmp commands get run via the model or the controller?

Thanks

I would create a model that will run your snmpwalk and parse the
results into some sort of object or a collection of objects. Then,
you would call that from your controller.

For example:

Say you have a processes controller with a show method. It calls the
SystemProcess model, which is simply something you wrote to walk the
process tree and put that into an array of Process objects.

(This below is for MERB, not Rails, but its very similar. I think you
can get the point of it.)

def show
  begin
    @process = SystemProcess.find_by_host(params[:hostname])
  rescue Exception => e
    raise NotFound.new(e.message)
  end
  if params[:process]
    @process = @process.select {|s|

Regexp.new(params[:process],true).match(
s.name) }
end
respond_to do |f|
f.txt { render_no_layout }
f.xml { render }
f.html { render }
end
end

So, that returns to you an @process object, which you can then render
in your views. If there was a process param passed, then we will go
through the collection of processes and only keep ones that match
whatever regex was passed.

That helpful?
