Using this index definition:

class PersonIndex(indexes.SearchIndex, indexes.Indexable):

      text = indexes.CharField(document=True, use_template=True)
      name = indexes.CharField()
      academy_member = indexes.BooleanField(default=False)
      birth_date = indexes.DateField(model_attr="start_date", null=True, faceted=True)
      death_date = indexes.DateField(model_attr="end_date", null=True, faceted=True)
      place_of_birth = indexes.CharField(null=True, faceted=True)
      place_of_death = indexes.CharField(null=True, faceted=True)
      gender = indexes.CharField(null=True, model_attr="gender", faceted=True)
      profession = indexes.MultiValueField(null=True, faceted=True)
      akademiemitgliedschaft = indexes.MultiValueField(null=True, faceted=True)

      def get_model(self):
          return Person

      def prepare_akademiemitgliedschaft(self, object):
          res = object.personinstitution_set.filter(
              related_institution_id__in=[2, 3, 500],
              relation_type_id__in=classes["mitgliedschaft"][0],
          )
          res_fin = []
          for mitglied in res:
              mitgliedschaft = get_mitgliedschaft_from_relation(mitglied.relation_type)
              res_fin.append(
                  f"{mitgliedschaft}__{str(mitglied.related_institution)}__{mitglied.start_date}__{mitglied.end_date}"
              )
          return res_fin

      def prepare_profession(self, object):
          return [x.label for x in object.profession.all()]

      def prepare_place_of_birth(self, object):
          rel = object.personplace_set.filter(
              relation_type_id__in=getattr(settings, "BIRTH_REL_NAME", [])
          )
          if rel.count() == 1:
              return rel[0].related_place.name
          else:
              return None

      def prepare_place_of_death(self, object):
          rel = object.personplace_set.filter(
              relation_type_id__in=getattr(settings, "DEATH_REL_NAME", [])
          )
          if rel.count() == 1:
              return rel[0].related_place.name
          else:
              return None

      def prepare_academy_member(self, object):
          if (
              object.personinstitution_set.filter(
                  relation_type_id__in=classes["mitgliedschaft"][0],
                  related_institution_id__in=[2, 3, 500],
              ).count()
              > 0
          ):
              return True
          else:
              return False

      def prepare_name(self, object):
          return str(object)
  ```

that actually produces a fine schema.xml with the correct field definitions

I get something along the lines of:

```json
{
        "id":"apis_entities.person.502",
        "django_ct":["apis_entities.person"],
        "django_id":[502],
        "text":["{'first_name': 'Rainer', 'name': 'Abart', 'alternative_names': [], 'texts': []}"],
        "name":["Abart, Rainer"],
        "academy_member":[true],
        "birth_date":["1963-10-30T00:00:00Z"],
        "birth_date_exact":["1963-10-30T00:00:00Z"],
        "place_of_birth":["Mödling"],
        "place_of_birth_exact":["Mödling"],
        "gender":["male"],
        "gender_exact":["male"],
        "akademiemitgliedschaft":["k. M. I.__MATHEMATISCH-NATURWISSENSCHAFTLICHE KLASSE__2013-04-19__None"],
        "akademiemitgliedschaft_exact":["k. M. I.__MATHEMATISCH-NATURWISSENSCHAFTLICHE KLASSE__2013-04-19__None"],
        "_version_":1696936035385081856},

where even the django_id is an array rather than an int.

I am sorry, I should have looked a bit closer. When debugging the problem I found that I had created a schema-less solr core. Now its working as intended. Closing the issue.
