Question

I have a controller and every method of it starts with the following code:

@user = UserData.find_by_login(session[:cuser])

if @user == nil
  redirect_to(:controller=> 'user_data', :action=> 'login')
  return
end

I’m just wondering if it is possible to avoid code duplication in this case ?

Answer 1

Yes, use a before_filter

class YourController < ApplicationController

  before_filter :check_user

  def check_user
  ..
  end

end
