ModelSelect2Widget url

[JD99]

Привет, не загружаются данные в виджет.

В консоли вижу что запросы уходят. Но идут просто на ту же страницу. Сервер честно ему отвечает шаблоном основной страницы. Возможно где-то нужно указать url по которому нужно забирать данные? Подскажите как решить вопрос.

GET /fields/?field_id=MTQwMTQ4MzY2MjIwMDMy%3A1hXmp1%3ArbO7eVuT0469hnhZuV4AerqvBqs HTTP/1.1" 200 24809

Code Snippet

class FormFilter(forms.Form): 
    things = forms.ModelChoiceField(
        queryset=project_models.Crop.objects.filter(filtervo=True),
        label=u"Crop",
        widget=select2_forms.ModelSelect2Widget(
            search_fields=['crop__icontains'],
            model=project_models.Crop,
        )
    )

в итоге закостылил редиректом

@JD99 Привет! Кор контрибьюторы не говорят по русски, поэтому им будет тяжело понять твой вопрос. Я попробую перевести, но если сможешь уточнить детали, пиши на английском (hey, I am afraid core contributors are not speaking russian, so it would be hard for them to get your question. I'll try to translate, but if you can add more details, please add them in english).

Original question:

I cannot load data to the widget.
I can see that there are requests in the logs, but they are going to the same page. Server returns the full template of a main page. Maybe I should define a certain url somewhere for loading data?

        label=u"Crop",
        widget=select2_forms.ModelSelect2Widget(

            model=project_models.Crop,
        )

@JD99 please, check the next API reference for HeavySelect2Widget (which is a base for ModelSelect2Widget).

This might get you to the right answer.

thanks @JD99 :)

@JD99 you might want to double check your URL configuration. Make sure the following is added to the beginning of your URL root configuration:

path('select2/', include('django_select2.urls')),

[JD99]

hi

project/urls.py

path(r'select2/', include('django_select2.urls')),
path(r'', include('main.urls')),
path(r'fields/', include('fields.urls'))

fields/urls.py

path(r'', views.view_list, name='fields')

fields/forms.py

class FormFilter(forms.Form):
    cropvo = forms.ModelChoiceField(
        label=u"xxx",
        queryset=project_models.Cropsvo.objects.order_by('cropvo'),
        widget=select2_forms.ModelSelect2Widget(
            model=project_models.Cropsvo,
            search_fields=['cropvo__icontains']
        )
    )

[JD99]

temporarily add redirect in fields/urls.py

def view_list(request):
    if 'term' in request.GET or 'field_id' in request.GET:
        path = '/select2{0}auto.json?{1}'.format(
            request.META['PATH_INFO'], request.GET.urlencode())
        return HttpResponseRedirect(path)

[Johannes Maron]

That is strange it does point correctly to /select2/fields/auto.json. Did you customize your JavaScript in any way?

[JD99]

Javascript didn't change

[JD99]

Found what the problem was. select2 library was connected in head

<head>
<script src="plugins/select2/select2.min.js"></script>
</head>

and

{{ formfilter.media.js }}

thanks for the help
