Ich versuche ein Formular zu erstellen, wo ich mehrere Objekte zu einer Liste hinzufügen kann. Wenn ich versuche, das Formset zu verwenden, bekomme ich den Fehler, alles scheint zu funktionieren, wenn ich das Formset aus der Vorlage entferne.Formset sollte ein gültiges Django Formset enthalten
Parameter "formset" should contain a valid Django Formset.
Ich habe mehrere Beispiele betrachtet, aber keine scheint zu funktionieren.
Vorlage:
<form action="{% url 'usermanager:organization_edit_details' organization.id %}" method="post" class="form">
{% csrf_token %}
{% bootstrap_form form layout='inline' %}
{%bootstrap_formset formset %}
{% buttons %}
<button type="submit" class="btn btn-primary">
{% bootstrap_icon "star" %}Submit
</button><button class="btn btn-primary">Cancel -dead</button>
{% endbuttons %}
</form>
view.py
def organization_edit_details(request, organization_id):
organization = get_object_or_404(Organization, pk=organization_id)
form = OrganizationForm(request.POST or None, request.FILES or None, instance=organization)
formset = StaffFormSet(request.POST or None, instance = organization)
if form.is_valid():
organization.organization_name = form.cleaned_data['organization_name']
organization.description = form.cleaned_data['description']
organization.rules = form.cleaned_data['rules']
organization.open_times = form.cleaned_data['open_times']
organization.website = form.cleaned_data['website']
organization.email = form.cleaned_data['email']

organization.postcode = form.cleaned_data['postcode']
organization.country = form.cleaned_data['country']
organization.kvk_number = form.cleaned_data['kvk_number']
organization.save()
if formset.is_valid():
return HttpResponseRedirect(reverse('usermanager:organization_edit_details'))
return render(request, 'user_manager/organizationEdit.html',{'organization':organization, 'form':form})

{% bootstrap_formset formset%} bis {% bootstrap_formset formset%} –
ich denke 'formset = StaffFormSet (request.POST oder None, instance = Organisation)' Instanz zum Personalmodell. aber nicht Organisation .. –
