如何在Django中预填充表单字段。在形成订单表单时，从User类预填充的数据是什么？
The result need like this:
我的看法

def order_create(request):
    cart = Cart(request)
    user = request.user
    if request.user.is_authenticated:
        if request.method == 'POST':
            form = OrderCreateForm(request.POST)
            if form.is_valid():
                order = form.save(commit=False)
                if cart.coupon:
                    order.coupon = cart.coupon
                    order.discount = cart.coupon.discount
                order.save()
                for item in cart:
                    OrderItem.objects.create(order=order,
                                            product=item['product'],
                                            price=item['price'],
                                            quantity=item['quantity'])
                cart.clear()
                order_created.delay(order.id)
                request.session['order_id'] = order.id
                return redirect(reverse('payment:process'))
        else:
            form = OrderCreateForm()
    else: 
        return redirect('login')
    return render(request,
                  'orders/order/create.html',
                  {'cart': cart, 'form': form})

我的形式

class OrderCreateForm(forms.ModelForm):

    class Meta:
        model = Order
        fields = ['first_name', 'last_name', 'email',
                  'address', 'postal_code', 'city']

我的模板

<form action="." method="post" class="order-form">
        {{ form.as_p }}
        <p><input type="submit" value="Place order"></p>
        {% csrf_token %}
</form>

我尝试使用初始化，但没有结果。
