I'm getting stuck on an error I'm getting when signing up a new user in Michael Hart's Ruby on Rails Tutorial. I'm new to rails but I've been searching for hours and can't seem to find anything to figure out the issue. My initial thought is that it's specific to the following line:

redirect_to @user

This is my file for users_controller.rb

#!/bin/env ruby
# encoding: utf-8

class UsersController < ApplicationController

def show
    @user = User.find(params[:id])
end

def new
  @user = User.new
end

def create
    @user = User.new(params[:user])
    if @user.save
        flash[:success] = "Welcome to the Sample App!"
    ??????????????    redirect_to @user
    else
        render 'new'
    end
end
end

This is the error message I get:

NoMethodError in UsersController#create

undefined method `??????????????' for # Rails.root: /Users/mikedeverna/Documents/rails_projects/sample_app

Application Trace | Framework Trace | Full Trace app/controllers/users_controller.rb:18:in `create'

Here is the code in my routes.rb file:

SampleApp::Application.routes.draw do

resources :users resources :sessions, only: [:new, :create, :destroy]

root to: 'static_pages#home'
match '/signup',  to: 'users#new'
match '/signin', to: 'sessions#new'
match '/signout', to: 'sessions#destroy', via: :delete
match '/help',    to: 'static_pages#help'
match '/about',   to: 'static_pages#about'
match '/contact', to: 'static_pages#contact'
