link_to parameter used in controller

rubyonrails-talk

okay, so ive got a view page of 'columns', each comprised of a name and code. ive got a button to 'add columns' and i want it to pass it an integer parameter so i can set up the default number of boxes for adding

so in my view ive got

= link_to "Add columns", new_column_path, :number => 5

and in my controller:

def new   @columns =   params[:number].to_i.times { @columns << Column.new } end

so basically i just want to read number passed from the link. there will be links from other places that have different values passed (not 5) what am i doing wrong? or is there a better way of approaching it?

Try link_to "Add columns", new_column_path( :number => 5 )
