Generating one page with multiple controllers

Hi,

So I have an application in rails. The purpose of the application is to
display test results written to the database. Each test consists of
several defined operations. Each operation can have multiple sub
operations (witch results in a tree like structure). Some of the defined
operations have to be displayed in a uniq way and some have a default
view. Also Most of the tests have some uniq summary.
So the main way to display the test is to display the operations that
where used in it. In a first view only the root operations are
displayed. And if a user is interested in the operation he can click on
it expanding it.
So my current version of the application reads the root operations
associated with a test. Based on a operation definition there is a big
case statement witch is used to map operation to a specific shared view.
This is done via partial renders witch update parts of the page via
ajax. So on one html page I have different parts of it (operations)
controlled by different view’s (but not controllers – there is only one
controller). The logic to each operation is added via helpers.

So this actual works but… I don’t like the solution because all the
application logic is located in helpers and shared partial view’s. As I
understand rails concept is to put the application logic into
controllers. But I don’t know how to use multiple controllers to create
one page (each controller has to have control of a part of a page). I’m
looking for a way to design the application in a more scalable way
because my solution is a little messy… ;).
Any ideas would be appreciated.

You can use MVC paradigm to your application interface, too. As you
describe it, It sounds that is the client side which must handle the
logic; well, design it using MVC. This article from A List Apart may
be useful:

Not really. Most of the logic should go in the models.
