Ruby-on-rails – Override devise registrations controller

deviseruby-on-rails

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?

Best Answer

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"}
