passing parameters to action

Hi,
I have this action in my controller:

def someAction(someParam)
....
end

I want to call this action from JS
like so:

<%= remote_function (:url => {:action => "someAction",
:someParam => 3})
%>

but this doesn''t work. How can I pass an argument to a controller
(eficiently)?
Thanks for your help!

Re: passing parameters to action

The solution I found is this:

def someAction
...
    @newParam = params[:someParam]   #@newParam is now 3
...
end

<%= remote_function (:url => {:action => "someAction",
:someParam =>
"3"})%>

cheers

ps. if there is a better way, I''d like to know, please.

Re: passing parameters to action

Controller methods doesn''t work like that.

Say you have this: link_to "Test", :action =>
"test_action", :id => 5,
:some_param => "test"

This would be the controller:

def test_action
  params[:id] #returns 5
  params[:some_param] #returns "test"
end

Re: passing parameters to action

By the way, I''m pretty sure rails wants you to name your actions
some_action, not someAction.

Thank you for showing me that. Yes, I''m naming my actions with
''_'' but I
have so strange names I have to rename them for forum;).
Thanks!

I have found that I can pass arrays to action like: :action => 
"test_action", :id={1,2,3}. Is this ok, or is it
"rail-abuse";)?
thanks
