Just need some quick help with syntax

I'm using strong_parameters for Treebook like this

#Permit Additional Paramaters for sign_up
before_filter :configure_permitted_parameters, if: :devise_controller?
protected
  def configure_permitted_parameters
    devise_parameter_sanitizer.for(:sign_up) << :profile_name
    devise_parameter_sanitizer.for(:sign_up) << :first_name
    devise_parameter_sanitizer.for(:sign_up) << :last_name      
end

Is there a way to put those three lines as one line?

Cheers,

Tom

Nevermind, found it.

devise_parameter_sanitizer.for(:sign_up) << :first_name << :last_name << :profile_name

Alternatively, 

devise_parameter_sanitizer.for(:sign_up) << [:first_name, :last_name, :profile_name]

works, but I think that's pushing a new array into an array so I think the top is better form yes? It's good enough for me anyhoo.
