congratulations on finding probably the last missing field. i guess it got past me because it has not direct mapping in rest_framework.serializers.ModelSerializer.serializer_field_mapping

easy fix

[jayvdb]

congratulations

thx. I try.

rest_framework.serializers.ModelSerializer.serializer_field_mapping

should that omission be raised upstream?

fwiw, I am happy to do a bunch of these easy fixes so you can focus on that harder ones.
I'm just raising the things I see as I investigate the result on this new generation; only the exception is important, the rest are just ways to reduce the length of the output for the next adoptee.

i found that it is not in the list but appended later. so no upstream issue.

sure thing. thanks.

@jayvdb could have added a regex for. that would have been the cherry on top but plain string should do it also. please close on fix confirmation.

[jayvdb]

Plain string is good enough; can always revisit later. Much appreciated.
