How to make a user profile + gem devise?

Question

Ruby on Rails

I want to bind to the User model (this is the essence of the devise gem) user profile.
I do the following:
1) rails generate devise User
Default setting + migration, everything is over.
2) rails g scaffold profile name:string role:string user:references
3) After generation I add has_one :profiles to the User model
In the rails console, in the database itself, I can't find the binding by id
Where did I go wrong?
Advise the decision, I need that after an input each user had the own profile.

Answer 1

model/user.rb
In the Devise controller:

class DeviseOverride::RegistrationsController < Devise::RegistrationsController
  def create
    super
    if resource.save
      resource.create_profile
    end
  end

Answer 2

has_one :profiles
I translate:
it has one profile and
And how is the Profile model connected to the User then?
