How to have AutoModelSelect2Field prepopulated on edit?

[Natim]

We are using AutoModelSelect2Field like that:

from django_select2.fields import AutoModelSelect2Field


class EmployeeChoices(AutoModelSelect2Field):
    search_fields = ('last_name__icontains', 'first_name__icontains')

    def get_queryset(self):
        current_site = Site.objects.get_current()
        return User.objects.of_site(current_site).employees()

    def set_queryset(self, queryset):
        pass

    queryset = property(get_queryset, set_queryset)


class TicketForm(forms.ModelForm):
    employee = EmployeeChoices(label=_('Employee'), required=False)

    class Meta:
        model = Ticket
        fields = ('employee', 'subject', 'body', 'priority')

But when we load the ModelForm with an instance, the employee field is empty instead of containing the instance value.

Do you have any idea what's wrong?

It could be very nice to be able to define get_queryset() without having to use this awkward trick.

Actually it seams that the problem come from the property. I will try a solution with SimpleLazyObject for current_site

Something like that works but it is not fast forward to get:

from django_select2.fields import AutoModelSelect2Field
from django.utils.functional import SimpleLazyObject


class EmployeeChoices(AutoModelSelect2Field):
    search_fields = ('last_name__icontains', 'first_name__icontains')
    queryset = People.objects.of_site(
        SimpleLazyObject(Site.objects.get_current)).employees()

Refs #61 — I remember I already started a PULL request in order to be able to define get_queryset() and you merged it. Can you please make a django-select2 release?

Yes will do that shortly. Did you try the manual tests in testapp? If they are fine then it can be released. I did not get a chance to do that myself.

Then we should setup a travis :)

I tried to run the test but there is no tests ...
What are you talking about?

[applegrew]

When you run testapp the various links you see are the manual tests. Basically you click them and see the fields in there are working as expected. The links briefly describe what is the expected behaviour.

[Natim]

I will have a look.

It works well :)

Many thanks to you :)
