Change Django ModelChoiceField to show users' full names rather than usernames

Question

I have a form in my Django app (not in admin) that allows staff members to select a user from a dropdown.

forms.ModelChoiceField(queryset = User.objects.filt

If you want to change choices of the field in model form, try this adaptation of the Bartek's answer:

model:

class MyModel(models.Model)
    user = models.ForeignKey(...)

form field:

class UserModelChoiceField(forms.ModelChoiceField):
    def label_from_instance(self, obj):
        return obj.get_full_name()

form:

class MyModelForm(forms.ModelForm):
    class Meta:
        model = MyModel
        fields = ['user']
        field_classes = {
            'user': UserModelChoiceField
        }

This approach will preserve params of the field (you don't need to specify queryset, required and so on).
