Using django-select2 and class based views with s2forms.ModelSelect2MultipleWidget

[swwlee]

Hi all,

I am using a CBV and have no issues with django-selelect2 with a CreateView. However, I do have issues with an UpdateView where I need to retrieve the value from the database and have the form show the selected the value. I have two fields and my 'name' column works correctly in that it retrieves the value correctly 9and also updates) as I have used similar CBV but the clientfield doesn't that uses s2form.

Can someone provide a similar example using UpdateView and multiple choice field or widget?

`class ProcessMappingGroupUpdateView(SuccessMessageMixin, LoginRequiredMixin, UpdateView):
model = ProcessOrchestration
context_object_name = None
form_class = GroupingForm
template_name = "portal/csp/billing/mappings-edit.html"
success_url = "/billing-mappings"

def get_object(self):
    pkid = self.kwargs.get("pk")
    return get_object_or_404(ProcessOrchestration, id=pkid)

def get_context_data(self, **kwargs):
    context = super().get_context_data(**kwargs)
    context["object"] = self.get_object()
    context["active_menu"] = "billing"
    context["segment"] = "mappings"
    context["crud"] = "Update"
    return context`

` class Meta:
model = ProcessOrchestration
fields = {
'name',
'clientfield'
}

    widgets = {
        'name': forms.TextInput(
            attrs={
                'class': 'form-control',
                'placeholder': 'Name',
                'required' : 'True',
            }),
    }

clientfield = forms.ModelMultipleChoiceField(
    queryset = Client.objects.filter().only('name','id').order_by('name'),
    label = "Clients",
    widget = s2forms.ModelSelect2MultipleWidget(
        model = Client,
        required = True,
        search_fields = ['name__icontains'],
        attrs={
            'data-minimum-input-length': 0,
        },
    ),
)`
