store_attribute

Features

• Added configuration option to return default values when attribute key is not present in the serialized value.

class ApplicationRecord < ActiveRecord::Base
  self.store_attribute_unset_values_fallback_to_default = true

  store_attribute :extra, :color, :string, default: "grey"
end

user = User.create!(extra: {})
# without the fallback
user.color #=> nil
# with fallback
user.color #=> "grey"

This release bring major improvements to the way we interact with ActiveRecord:

• Use existing Attributes API and Store API instead of duplicating and monkey-patching
• Dirty-tracking, accessors and prefixes/suffixes are now handled by Rails—we're no longer trying to re-implement this.

Thus, we only provide type coercions for stores. That's it.

P.S. The only internal patch that's left is the MutationTracker patch which allows you to have granular #changes for stores.
