Usage in inline_formset

[asqarsakenov]

Hi! Thanks for your code. It works pretty fine, until I use a formset. Formset forms only show the current selected or empty drop-down. Do you have any suggestions?

# views.py

def invoice_line_create_view(request, pk):
    InvoiceLineFormSet = inlineformset_factory(Invoice2, InvoiceLine2, form=LineForm, extra=10)
    invoice = get_object_or_404(Invoice2, pk=pk)
    formset = InvoiceLineFormSet(instance=invoice)
    if request.method == 'POST':
        # print(f"{get_cache_key(request)} kod")
        formset = InvoiceLineFormSet(request.POST, instance=invoice)
        if formset.is_valid():
            formset.save()
            return redirect('invoice_detail', pk=invoice.pk)

    context = {
        'invoice': invoice,
        'formset': formset,
    }

    return render(request, './invoice/invoice_line_new.html', context)

<!-- invoice/invoice_line_new.html -->
{% extends 'base.html' %}

    {{ formset.management_form }} 
          {% for form in formset %}

# forms.py

class LineForm(forms.ModelForm):
    class Meta:
        model = InvoiceLine2  
        # fields = ["name", "type_field"]
        fields = "__all__"
    name = forms.ModelChoiceField(
        queryset=Name2.objects.all(),
        label="Наименование",
        widget=s2forms.ModelSelect2Widget(
            model=Name2,
            search_fields=['name__icontains'],
            attrs={
                "data-minimum-input-length": 0,
                "data-placeholder": "Выберите Наименование",
                "data-close-on-select": "true",
                "data-allow-clear" : "true",
            },
            # dependent_fields={'type_field': 'types'},

        )
    )

    type_field = forms.ModelChoiceField(
        queryset=Price2.objects.all(),
        label="Тип",
        widget=s2forms.ModelSelect2Widget(
            model=Price2,
            search_fields=['type_field__icontains'],
            attrs={
                "data-minimum-input-length": 0,
                "data-placeholder": "Выберите Тип",
                "data-close-on-select": "true",
                "data-allow-clear" : "true",

            },
            dependent_fields={'name': 'name'},
            max_results=500,
        )
    )
