Rails - Mar 2006 - Best way about doing this?

Hi All,
I''m super a super ruby nuby, so bare with me.  I am working on a small 
app that has a particular form that I am having a rough time figuring 
out the best to way to handle.

Basically here it is, each school has one or more classrooms, and each 
classroom can have one or more teachers.

Here''s what I am trying to do (edit a school):
 - click on a link to edit a School
 - The school form loads and with it, all it''s classrooms are listed (I
have this part ok)
 - part I''m trying to think of how to do is:
  - for each classroom, grabbing all the teachers...Would do this in the 
controller or the rhtml file itself?  If in the controller, how?  It''s 
probably a stupid question, but I can''t see it.  Can you do a loop 
through each of the classrooms and assign them an array of teachers?

here is the controller for the form so far:
	def view_school
		@school = School.find(params[:id])
		@classrooms = Classroom.find(:all,
		:conditions => ["school_id = ?", params[:id])
	end

It should be tied to your model.  If you are using the built-in
associations, you would have

  class Classroom

  has_many :teachers

For more info on ActiveRecord Associations visit:
http://api.rubyonrails.org/classes/ActiveRecord/Associations/ClassMethods.html


You could loop through your @classrooms within your view using something like:

<% @classrooms.each do |classroom| %>
 ...
<% end %>

Then for each classroom in your view, you could access the array of
teachers using:

  classroom.teachers

Hope that helps.
