DAL v3: ModelSelect2 with form initial does not respect get_result_label

hello, I’m moving to DAL v3. I wonder if it is possible that the value set to form the initial, is shown as get_result_label

Sample code

views.py

from django.views import generic
from django.db.models import Q
from django.core.urlresolvers import reverse_lazy
from django.contrib.auth.models import User
from dal import autocomplete

from .models import SampleModel
from .forms import SampleForm


class UserAutocomplete(autocomplete.Select2QuerySetView):
    def get_queryset(self):
        # Don't forget to filter out results depending on the visitor !
        if not self.request.user.is_authenticated():
            return User.objects.none()

        qs = User.objects.all()

        if self.q:
            qs = qs.filter(Q(first_name__icontains=self.q) | Q(last_name__icontains=self.q))
        return qs

    def get_result_label(self, result):
        return result.get_full_name().title()


class SampleView(generic.UpdateView):
    form_class = SampleForm
    model = SampleModel

    def get_success_url(self):
        return reverse_lazy('sample_update', {'pk': self.object.pk})

    def get_initial(self):
        initial = super(SampleView, self).get_initial()
        user = getattr(self.request, 'user', None)
        if user and user.is_authenticated():
            initial.update({'selected_user': user})
        return initial

models.py

from django.db import models
from django.contrib.auth.models import User


class SampleModel(models.Model):
    selected_user = models.ForeignKey(to=User,
                                      related_name="%(app_label)s_%(class)s_selected_user", null=True,
                                      blank=True, on_delete=models.SET_NULL)

forms.py

from dal import autocomplete
from django import forms
from django.contrib.auth.models import User
from .models import SampleModel


class SampleForm(forms.ModelForm):
    selected_user = forms.ModelChoiceField(
        queryset=User.objects.all(),
        widget=autocomplete.ModelSelect2(url='user-autocomplete')
    )

    class Meta:
        models = SampleModel
        fields = '__all__'

urls.py

from django.conf.urls import url
from . import views

urlpatterns = [
    url(r'^sample-update/(?P<pk>\d+)/$',
        views.SampleView.as_view(),
        name='sample_update'
        ),
    url(r'^user-autocomplete/$',
        views.UserAutocomplete.as_view(),
        name='user-autocomplete'
        )
]

RESOLVED!!

This is not a problem DAL v3.

it was necessary to create a new class that inherits from forms.ModelChoiceField and create a label_from_instance method which returns the value of the label that need.

look at the end of the ModelChoiceField documentation https://docs.djangoproject.com/es/1.9/ref/forms/fields/#modelchoicefield

this would be a good example to include in the documentation, because I believe it is a common use.

from dal import autocomplete
from django import forms
from django.contrib.auth.models import User
from .models import SampleModel


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

class SampleForm(forms.ModelForm):
    selected_user = UserModelChoiceField(
        queryset=User.objects.all(),
        widget=autocomplete.ModelSelect2(url='user-autocomplete')
    )

    class Meta:
        models = SampleModel
        fields = '__all__'

@jpic thank you for the incredible work.
