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
Pagination links will be included in your response automatically as long
as the resource is paginated using Kaminari or WillPaginate
and if you are using a JSON-API adapter. The others adapters does not have this feature.
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
