Is it possible to put validations in controllers in Ruby on Rails?

Question

I have an additional member method (and a corresponding route) called download, for which I'd like to validate the existence of a password field. Putting :validates_presence_of :password in my download method, I get an error claiming it's an undefined method.

Is this possible?

No, you can add errors to the model but validations live in the model. Check out the errors methods and add_to_base if you need to add errors in the controller for whatever reason.
