Breaking change:
- Adapters now inherit Adapter::Base
- 'Adapter' is now a module, no longer a class
Why?
- using a class as a namespace that you also inherit from is complicated and circular at time i.e.
buggy (see https://github.com/rails-api/active_model_serializers/pull/1177)
- The class methods on Adapter aren't necessarily related to the instance methods, they're more
Adapter functions
- named `Base` because it's a Rails-ism
- It helps to isolate and highlight what the Adapter interface actually is
Comparing as a JSON string vs. as the Hash that is convert to JSON
works around the different Hash representations.
This likely has to do with the introduction of
config.action_dispatch.perform_deep_munge in Rails 4.1
See Rails issue 13420
