About Model Choice Fields
By default, django.forms.ModelChoiceField uses the __str__() method of the model to represent the items in the option list.
When your __str__() representations are not unique, you can extend the ModelChoiceField and overwrite the label_from_instance(self, obj) method and display custom unique options:
from django.forms import ModelChoiceField
class ModelChoiceFieldWithIDs(ModelChoiceField):
def label_from_instance(self, obj):
return f"{obj.title} (ID={obj.pk})"
