Question

How do I increment “week” property?

def newweek
 current_user.userprofile.week += 1
 respond_to do |format|
  format.html { redirect_to :action => "index"}
 end
end

The initial value is 0. Each time newweek is run, the week should be incremented by 1.

Unfortunately, each time newwek is run, the value remains to 1. How do I fix that?

EDIT

class NewWeekToUserprofile < ActiveRecord::Migration
  def change
     add_column :userprofiles, :week, :integer, :default => 0
  end
end

You could use .increment method.

current_user.userprofile.increment :week
