Maybe I'm doing something wrong here but the automatically generated links based foreign key relationships seem to be working here for utility_id_eia, but not for plant_id_eia & generator_id which seems odd: https://pudl-datasette-xl7xwcpe2a-uc.a.run.app/pudl/generators_eia860

Right now it seems like they're trying to, but with only one of the two keys, so it gives "Error 500. You did not supply a value for binding 2." Maybe only create the links when it's a simple foreign key?
