Django Admin overwrite the str method in an autocomplete_field

Question

I want to overwrite the __str__ method in Django admin when using the autocomplete_fields = () but the returned values are using __str__.

I have a form something like

class MyAdminForm(forms.ModelForm):
        
    placement = forms.Select(
        choices = Organisation.objects.active(),
    )

    class Meta:
        model = Lead
        fields = '__all__'

    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.fields['placement'].label_from_instance = lambda obj: f'{str(obj)} {obj.post_code}'

This will provide back a Select with the organisation name and post code in the dropdown fields. But there are some 80k choices so I need to using autocomplete. Within within admin.py I have

class LeadAdmin(admin.ModelAdmin):
    form = LeadAdminForm
    autocomplete_fields = ('placement',)

As soon as I add the autocomplete_fields I lose my postcode and it reverts to just showing the __str__

Hoa can I used autocomplete_fields and overwrite the __str__ method?

You cannot override the `__str__` method in your `Organisation` model ? — Benbb96, Feb 25 '21 at 13:33
Can you share the `Lead` model? Is `Lead.placement` a `ForeignKey`? — Iain Shelvington, Feb 25 '21 at 13:42
This is the only place I want to override the `__str__` method which is why I cannot override within the model — HenryM, Feb 25 '21 at 14:33
