title: Rails 4 Ignore Error/Exception and Continue
body: <p>Sorry if it's an easy question, I am pretty new to Ruby.</p>
  
  <p>When users sign up, or login I would like to keep statistics with Redis</p>
  
  <pre><code>def create
    @user = User.new(user_params)
    if @user.save
      $redis.hincrby("2016MMDD", "new_users", 1)
      render json: @user
    end
  end
  </code></pre>
  
  <p>If for any reason $redis.hincrby fails, is there a way to continue the execution of the code and render the user anyway?</p>
