PadrinoBlog users controller pre-refactor

users.rb

PadrinoBlog::App.controllers :users do

  get :new do
    @user = User.new
    render 'users/new'
  end

  post :create do
    user = User.new(params[:user])
    
    if user.save
      redirect('/sessions/new', notice: "Signed up successfully! Please Log in")
    elsif (params[:user][:password_confirmation] != "") && (params[:user][:password] != params[:user][:password_confirmation])
      redirect('/users/new', notice: "Password and Password Confirmation do not match. Please try again.")
    else
      redirect('/users/new', notice: "Please make sure you fill in all fields.")
    end
  end

end

For example:

PadrinoBlog::App.controllers :users do

  get :new do
    say_hello
  end

  def say_hello
    puts "hello"
  end
end

This won't work.

How do I refactor stuff out into methods? I can create external helper modules with methods inside them, and then include that module here and call its methods, but I'd rather not do that.

I'm thinking along the lines of Rails controllers, how you just refactor stuff out into private methods in the controller class. I want to do something similar here, but obviously I can't.
