* Introduce ApplicationRecord, an Active Record layer supertypeGenadi Samokovarov2015-12-161-24/+24
| | | | | | | | | | | | | | | | It's pretty common for folks to monkey patch `ActiveRecord::Base` to work around an issue or introduce extra functionality. Instead of shoving even more stuff in `ActiveRecord::Base`, `ApplicationRecord` can hold all those custom work the apps may need. Now, we don't wanna encourage all of the application models to inherit from `ActiveRecord::Base`, but we can encourage all the models that do, to inherit from `ApplicationRecord`. Newly generated applications have `app/models/application_record.rb` present by default. The model generators are smart enough to recognize that newly generated models have to inherit from `ApplicationRecord`, but only if it's present.
