Adding custom parameters to devise registration - unpermitted parameters

Question

I\'ve been trying to customize the devise register method to register with more parameters and also update more(no luck so far), but I always get Unpermitted parameter

Answer 1

For Devise 4.2.0 you can whitelist additional parameters for your users table by adding those values to keys. By default devise gives you the comment to go off of now. Below I added :avatar

  # If you have extra params to permit, append them to the sanitizer.
  def configure_sign_up_params
    devise_parameter_sanitizer.permit(:sign_up, keys: [:attribute, :avatar])
  end
