Question

Im using the ‘Devise’ gem on a rails 3.1.1 app for creating users and signing in, but i need to add fields for profile as @user.build_profile but i dont know where to add this, i also need to change the default redirect_to after signing in.

You can add the fields that you need to your models just as you normally would through a migration. If you are using the default devise views through rails generate devise:views, then you will want to add your fields to the new and edit views inside of the Registration views in devise.

As for changing the default redirect after sign_in, I would start with reading the Devise Wiki. You can simply add to your application controller:

 protected

      def stored_location_for(resource)
        nil
      end

      def after_sign_in_path_for(resource)
        #path to which you wish to redirect
      end
end

This will allow you to customize that route. You can also look at the registrations controller within devise to see the other methods that you can override.

Edit:

Overriding the controller:

You would create your own controller that inherits from Devise::RegistrationsController. From there you only need to specify the methods that you need to override, and not every single one. For instance:

def create
  build_resource
  resource.build_profile

  if resource.save
    set_flash_message :notice, :signed_up
    redirect_to after_sign_up_path_for(resource)
  else
    clean_up_passwords(resource)
    render_with_scope :new
  end
end

Then add the above lines for stored location and after_sign_in_path. You also have to tell Devise in your routes.rb to use your new controller with, devise_for :users, :controllers => { :registrations => 'your_controller_name } I have an example of this on my blog, and the full source is on Github.
