I know this may be a very basic question, but confusing me.
If I write the following for example in the controller:
@x = App.new(params[:x])
I know that I'm trying to create a new object here, but how can I read
the params[:x] part.
I know also that "params" is a Hash table in the controller, but what is
the following statement trying to say when passing [:x] to params? What
is this value?
From where will I retrieve it?
