bug with inclusion of polymorphic association

Exécutez la reproduction Minitest intégrée et comparez test_patch_linkage_options_with_android avec test_fetch_option_linked_with_android. Suivez la relation polymorphe optionable de OptionResource à travers le contrôleur et la route JSONAPI. Le travail est terminé lorsque les deux requêtes aboutissent et que l’association optionable peut être liée et incluse comme prévu par les tests.
