Thanks.. Well, I figured it out after I posted it on forum... While I know why passing parameter is working, I don't understand why first approach didn't work. Any clues?

You didn't mention the id of the topic which you are trying to show.. Also where you have created @topic object?
your first aproach was this:
def show @topic = @object @items = @topic.items end
where would @object come from. it's a new uninitialized variable (= nil). that's the reason it didn't work. what else did you expect than nil.items ?
