Keeps your API lookin' good! No need for all that nested_attributes pollution in your request/response payloads
class V1::AddressBooksController < V1::BaseController
def create
@address_book = AddressBook.new address_book_params
unless @address_book.save
errors = @address_book.errors.to_hash(true)
render status: 422, json: { errors: errors }
end
