ruby on rails - Override devise registrations controller

Question

I have added a field to the sign-up form that is based on a different model, see How do I use nested attributes with the devise model for the gory details. This part is working fine.

The problem now is when I save, it is failing in the create action of the registrations controller that is supplied by devise with an Activerecord::UnknownAttributeError on this field (company).

I am assuming I need to override the registrations controller, or is there a better/easier way I should be approaching this?

Answer 1

In your form are you passing in any other attributes, via mass assignment that don't belong to your user model, or any of the nested models?

If so, I believe the ActiveRecord::UnknownAttributeError is triggered in this instance.

Otherwise, I think you can just create your own controller, by generating something like this:

# app/controllers/registrations_controller.rb
class RegistrationsController < Devise::RegistrationsController
  def new
    super
  end

  def create
    # add custom create logic here
  end

  def update
    super
  end
end 

And then tell devise to use that controller instead of the default with:

# app/config/routes.rb
devise_for :users, :controllers => {:registrations => "registrations"}
