variable + param

Hello i am iterating over one record: it schema is:

id, name, content, content2, content3 and so on

i tried to do with other table to normalize it but ok,

the thing is that n the view to move to other content i send a param[:page] => :content2 or 3 or 4

in the controller i am trying to do this:

def section   ...   @section."#{param[:page]}"   ... end

how can i do to combine an object with a param, or other idea how to move on records like this?
