我正在嘗試製作一個表單，可以將多個對象添加到列表中。 當我嘗試使用formset時出現錯誤，當我從模板中刪除formset時，所有內容似乎都能正常工作。formset應該包含有效的Django Formset
Parameter "formset" should contain a valid Django Formset.
我看了很多例子，但似乎沒有工作。
模板：
<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.street_name = form.cleaned_data['street_name']
organization.street_number = form.cleaned_data['street_number']
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})

我認爲'formset = StaffFormSet（request.POST or None，instance = organization）'實例給staff模型。但不是組織.. –
