Strange question, but very interesting for me :)

So, you you wanna check, that user is NOT a robot - you can use captcha or something, that robots can't do well. But, if you need check, that user is a robot?

For example, we create some multiplayer game, were players will programming robots. [this just example, imagine, that we can't run user code on server]. In this case, user can create some UI for a this game and play game by himself. This is not good for a game balance and other game things.

So, we must check, that user is a robot!

We can send request like "calculate MD5 summ of this or that", but programmer can automatize only this part, and continue to play himself with UI.

So,how can we verify this?

ps. sorry for bad english, but i hope, you understand what I mean.

Hi guys, i just write this method: http://gist.github.com/mrThe/5143746

Why? Becouse i can write BaseController method like this:

  def check_params!(path, exception = "Not enough params")
    raise exception unless params.deep_symbolize_keys.path_exists?(path)
  end

And use it like this in needed controller action:

    check_params!({:user => [:email]}, "No email")

instead of

    raise "No email" unless params[:user] && params[:user][:email]

What do you think about this? Is it good idea?

/related to Ruby On Rails, i write some RESTful api app and every time will check input params.
