Problem with SearchFilter and JSONFields

[haaavk]

There is a problem with SearchFilter and JSONFields.
When I add json key to search_fields (json_field__key) I got exception:
django.core.exceptions.FieldDoesNotExist: Model has no field named 'field_name'
Exception comes from SearchFilter class and must_call_distinct method.
I made quick fix by overriding must_call_distinct method but it's not a perfect solution.

class JsonSearchFilter(SearchFilter):
    def must_call_distinct(self, queryset, search_fields):
        opts = queryset.model._meta
        search_fields = [
            field
            for field in search_fields
            if not isinstance(opts.get_field(field.split(LOOKUP_SEP)[0]), JSONField)
        ]
        return super().must_call_distinct(queryset, search_fields)

Also problem with full text search and JSONField:

disks, nics are JSONFields, test is CharField.

SELECT COUNT(*) AS "__count"
  FROM "monitor_server"
 WHERE (("monitor_server"."disks" -> 'search') = '"dell"'
       OR ("monitor_server"."nics" -> 'search') = '"dell"'
       OR to_tsvector(COALESCE("monitor_server"."test", '')) @@ (plainto_tsquery('dell')) = TRUE)
