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?

Regars,
