Hey all,

Is it possible to use ModelAdmin.formfield_overrides attribute to
customize a widget for only one field in an admin form, not for all
fields of a certain type in a model?

Say we have an admin class like this:

class MyModelAdmin(admin.ModelAdmin):
    formfield_overrides = {
        models.TextField: {
            'widget': forms.Textarea(attrs={'cols': '100', 'rows':
'20'})
        },
    }
admin.site.register(MyModel MyModelAdmin)

If there were more then one fields in MyModel of type TextField, all
of them would be affected. It would be useful to have a modifier
targeting a field instance, not a field type.

Best Regards,
