What if we will replace this code with

```ruby
class User::ParameterSanitizer < Devise::ParameterSanitizer
  USER_ATTRIBUTES = [:full_name]

  alias_method_chain :attributes_for, :user_attributes

  private

  def attributes_for_with_user_attributes(kind)
    USER_ATTRIBUTES + attributes_for_without_user_attributes
  end
end
```
