python - 动态保存表单

Question

我试图不在我的表单中使用 formset。相反，我尝试动态创建表单并将所有表单数据保存在数据库中。目前，我可以创建一个动态表单，但问题是即使我创建了多个表单，我也无法保存表单中的所有数据。现在我的代码只能保存一种形式。但我想将整个表单（带有多个表单数据）保存在数据库中。

视图.py

def create_order(request):
    from django import forms
    form = OrderForm()

    if request.method == 'POST':
        forms = OrderForm(request.POST)
        if forms.is_valid():
            po_id = forms.cleaned_data['po_id']
            supplier = forms.cleaned_data['supplier']
            product = forms.cleaned_data['product']
            part = forms.cleaned_data['part']

            order = Order.objects.create(
                po_id=po_id,
                supplier=supplier,
                product=product,
                part=part,
            )
            return redirect('order-list')
    context = {
        'form': form
    }
    return render(request, 'store/addOrder.html', context)

表格.py

class OrderForm(forms.ModelForm):
    class Meta:
        model = Order
        fields = ['supplier', 'product', 'part','po_id']

        widgets = {
            'supplier': forms.Select(attrs={'class': 'form-control', 'id': 'supplier'}),
            'product': forms.Select(attrs={'class': 'form-control', 'id': 'product'}),
            'part': forms.Select(attrs={'class': 'form-control', 'id': 'part'}),        
        }

HTML

<form action="#" method="post" id="form-container"  novalidate="novalidate">
                            {% csrf_token %}
                        <div class="form">

if request.method == 'POST':
    forms = OrderForm(request.POST)
    if forms.is_valid():
        po_id = forms.cleaned_data['po_id']
        supplier = forms.cleaned_data['supplier']
        product = forms.cleaned_data['product']
        part = forms.cleaned_data['part']
    
        forms.save()  # add save here 

        order = Order.objects.create(
            po_id=po_id,
            supplier=supplier,
            product=product,
            part=part,
        )
        
        return redirect('order-list')
