Tell us about your environment

Ruby Version:
3.0.4

Rails Version:
6.1.5.1

PostgreSQL Version:
12

Store Attribute Version:
1.0.1

What did you do?

Our rails app includes classes that aren't ActiveRecord classes. An example is below.

class TestObject
  include ActiveModel::Model
  include ActiveModel::Validations
  include ActiveModel::Dirty

  define_attribute_methods :content

  attr_reader :content

  def content=(value)
    @content = value
    content_will_change!
  end

  def reset_dirty_tracking
    changes_applied
  end
end

What did you expect to happen?

The behavior of class should not be changed by store_attribute.

What actually happened?

The following error occurs.

Minitest::UnexpectedError:         NoMethodError: undefined method `[]' for #            lib/rails_ext/active_record_mutation_tracker_extention.rb:8:in `change_to_attribute'

It appears "StoreAttribute::MutationTracker#change_to_attribute" expects the "attributes" to be an instance of "ActiveModel::LazyAttributeSet" when it (in this case) is an instance of the class – TestObject.
