Question

我的模板中有两个表单，我想要做的是将新添加的模型添加到另一个模型的属性中。模型分别是客户和订单。（一旦我添加了客户，我想向其客户添加订单，新添加的订单）

以下是我的客户观点

def add_customer(request):

    form = CustomerForm(request.POST or None)

    if form.is_valid():
        customer = form.save(commit=False)
        customer.save()

        context = {
            'form': OrderForm()
        }

        messages.success(request, "Customer added successfully!")
        return render(request, 'orders/add_order.html', context)

    context = {'form': form}
    return render(request, 'core/add_customer.html', context)

这是我的订单视图

def add_order(request):

    form = OrderForm(request.POST or None)
    orders = Order.objects.all()

    if form.is_valid():
        order = form.save(commit=False)
        order.save()

        messages.success(request, "Order placed")
        return render(request, 'orders/index.html', {'orders': orders})

    return render(request, 'orders/add_order.html', {'form': form})

这是我的模板

<a href="{% url 'core:add-customer' %}">
    <p><em>Click this to add a new customer</em></p>
</a>
<form method="post">
    {% csrf_token %}

    {% include 'core/form-template.html' %}

    <div align="center">
        <button class="btn btn-success"> Submit </button>
    </div>
</form>

但是，订单无法添加，因为它会抛出错误（需要此字段）

编辑：这是我的表格

OrderForm

class OrderForm(ModelForm):

    class Meta:
        model = Order
        fields = ['customer']

CustomerForm

class CustomerForm(ModelForm):

    class Meta:
        model = Customer
        fields = '__all__'

订单型号

class Order(models.Model):

    customer = models.ForeignKey(Customer)
    date_created = models.DateField(auto_now_add=True)

    def __str__(self):
        return str(self.customer)

客户模型

class Customer(models.Model):

    company_name = models.CharField(max_length=250, unique=True)
    contact_first_name = models.CharField(max_length=50)
    contact_last_name = models.CharField(max_length=50)
    contact_no = models.CharField(max_length=20)
    email_address = models.EmailField()
    address = models.CharField(max_length=400)

    def __str__(self):
        return self.company_name

django - 此字段是必填字段
