Sumbit form in rails

Is there a way in rails to choose controller action to which form will
be submitted?

Currently I have something like this:

VIEW:
<%= start_form_tag(:action => 'action_chooser', :id => @id %>
....
<%= hidden_field_tag("action_type") %>
<%= link_to_function "action1",
"document.frm.action_type.value='action1'; document.frm.submit()" %> <br>
<%= link_to_function "action2",
"document.frm.action_type.value='action2'; document.frm.submit()" %> <br>

CONTROLLER:

def action_chooser
   case action_type
     when 'action1'
          ...
     when 'action2'

I would like to have action1 and action2 functions in controller and
somehow choose on the client where to submit.

Thanks,
Igor.

Um, you can have the various actions as functions within the
Controller class. Why would you want to _choose_ actions from a
function within the controller?

Think about that as a web album.
I display multiple images on a page, with check box below each.
User selects some images and chose action: rotate, flip, delete, ...

So I need to post a form with selected check boxes, but the action depends on the user choice.

Sure you can. If you have a field like this:

<inut type="hidden" name="foo" value="bar" />

Then in the controller, you can write:

def action_chooser
  case @params['foo']
    when 'bar'
         ...
    when 'foobar'

Thanks Douglas,

That is exactly the same solution as I'm using now (I describe that in the first post), but I'm looking fore a more elegant solution (without case)
..
Any ideas?
Igor.
