Comment (by László Károlyi):
Replying to [comment:3 Tim Graham]:
> You might look at #17657 which was a fix for `to_field_name` and
`ModelMultipleChoiceField`. In that case, I think
`ModelMultipleChoiceField._check_values()` is doing the conversion from
initial pk values to `to_field_name` values. A proper fix most likely lies
in `ModelChoiceField` rather than `BoundField`; the latter shouldn't have
knowledge of specific fields.
Just took a look at it, it's doing basically the same what I implemented
in `ModelChoiceField.value()`.
For me it really doesn't matter where the underlying logic is, as long as
it works. Do you want me to uncomment the logic in `ModelChoiceField` and
update the pull request?
