[Ajax on Rails]How to pass an object via param

rubyonrails-talk

I'm trying to pass an object as a parameter on a link_to_remote. What I do is pretty simple: link_to_remote 'Insert subquestion', :url => {:action => 'add_subquestion', :question => @question}, :update => '', :method => :get

But, obviously, what I get is a string which has the address of the object. Can I "translate" this string back to the object? Is there a better way to pass an object as a param?

No. There is no way I know of to translate an address back into an actual object (although writing a ruby extension to do that is probably possible). Anyway, the request may have gone to a different mongrel or the original object may have been garbage collected

Is there a better way to pass an object as a param?

pass its id

But it's a new object. It doesn't have any id yet. But I think I have a solution. Instead of passing an id, adress or object_id, I'll pass it's subquestion's array length. Then all I have to do is put one more subquestion. Thank you, anyway.
