Rails - Oct 2005 - Calling other controller methods

What (if any) is the preferred way to call an action in controller B
from controller A and have execution return to controller A?

Basically, I have a "requests" controller.   New requests can be made
by
client users who have their own controller.  Since the new request code
can be called from two places, where do I put the code to read the form
and do the insert?

Guidance would be greatly appreciated.

Brian-
     You could use render_component_as_string like this:

Controller B

def test
     #whatever you want to do here to return some results
end

Controller A

def page
     @items = MyModel.find :all # or whatever
     @action_from_b = render_component_as_string :controller =>  
''b'', :action => ''test'', :params => {
:key => ''value'' }
end


     This should do a find on MyModel and put the results in @items  
for the view, then it will call the test action in controller b with  
some extra params(you can leave the params off if you don''t need  
them) and put the resulting string in @ action_from_b. Then it will  
render yor page.rhtml view of the a controller.

That''s brilliant... And that solves about 85% of my problems. How would
you call a method to submit data?

Say I have this in Controller a:

	def create
		@r = Request.new(params[''request'']
		if @r.save
			flash[:notice] = "Request saved"
			redirect_to :action => ''list'',
:pid=>params[''pid'']
		else
			render :action=>"new"
	end


For one reason or another, controller B needs to do the same thing...
Maybe even from the same form. I''m not quite getting how I should call
this from another controller.

I suppose I could just have my form in views/b/new.rhtml post data to
controller A, but that just doesn''t seem right to me (I''d have
to track
which controller they came from so I could route them back...)

Any ideas?
