How to add property to the select2 options?

[rez0n]

Hi, I need to manipulate form fields based on the selected item state.
For example, I have a services list to select one of them, it has boolean option require_details in Django model, I need to pass this boolean value to the select2 items to get it in JS.

Actually, one of the instance properties passed to the select2 options, it is id and I can get in JS this way

$('#id_service').select2('data')[0].id

So, I assume if it is possible to append select2 options by other details I may get it by

$('#id_service').select2('data')[0].require_details

Any ideas?
Thanks.

Hi @codingjoe
Please advise if you have an idea, actually, I can't find a particular core function that generates choices list for the select2.

Actually, I found a solution.
Choices list being generated in the view. So, to pass extra properties to the choices we need to use modified view
Example how to pass test property of the object

from django_select2.views import AutoResponseView
from django.http import JsonResponse

class ServiceSelect2View(AutoResponseView):
    def get(self, request, *args, **kwargs):
        self.widget = self.get_widget_or_404()
        self.term = kwargs.get("term", request.GET.get("term", ""))
        self.object_list = self.get_queryset()
        context = self.get_context_data()
        return JsonResponse(
            {
                "results": [
                    {"text": self.widget.label_from_instance(obj), "id": obj.pk, "test": obj.test }
                    for obj in context["object_list"]
                ],
                "more": context["page_obj"].has_next(),
            }
        )

urls.py

path('services/select/', ServiceSelect2View.as_view(), name='services_select2'),

forms/widgets

class ServicePickCreateWidget(s2forms.ModelSelect2TagWidget):
    ....
    def __init__(self, *args, **kwargs):
        kwargs['data_view'] = 'services_select2'
        super().__init__(*args, **kwargs)
...
