Changes between Version 4 and Version 5 of Ticket #32587

-              v4
+              v5
 Even if this issue a won't fix for any reason at least abstract fetching instance by in index in a `ge_instance_by_index` method so that we can implement admins that do what we want of top of current base classes. If this is done then we will be able to overwrite ge_instance_by_index to return `list(self.get_queryset())[i]`   instead of `self.get_queryset()[i]` on inlines that support prefetching
+Also I believe that the logic about preparing queryset in BaseInlineFormSet should exist in a separate function called `prepare_queryset`:
+{{{
+def prepare_queryset(queryset):
+        if queryset is None:
+            queryset = self.model._default_manager
+        if self.instance.pk is not None:
+            qs = queryset.filter(**{self.fk.name: self.instance})
+        else:
+            qs = queryset.none()
+        return qs
+}}}
+instead if throwing it `__init__` Intit could just call the above to get the value . This way filtering wouldn't be enforced in the case of related manager querysets since we could overwrite the method.
