找不到’basket_adding’的相反内容。’basket_adding’不是有效的视图函数或模式名称。

ajax和jquery错误

url(r'^basket_adding/$', basket_adding, name="basket_adding"),

这是我的产品的views.py

def product_view(request, slug=None):
    instance                        = get_object_or_404(Product, slug=slug)
    title                           = instance.name
    session_key                     = request.session.session_key
    if not session_key:
        request.session.cycle_key()
    forms                           = SubscribersForm(request.POST or None)
    if forms.is_valid():
        instance                    = forms.save(commit=False)
        instance.save()
        return redirect("/")
    context = {
                "instance": instance,
                "title": title,
                "forms": forms,
    }
    return render(request, 'product.html', context)

这是我的订单views.py

def basket_adding(request):
    return_dict                     = {}
    session_key                     = request.session.session_key
    data                            = request.POST
    product_id                      = data.get('product_id')
    product_price                   = data.get('product_price')

    new_product                     = ProducInBasket.objects.get(session_key=session_key, product_id=product_id, product_price=product_price, quantity=quantity)
    return JsonResponse(return_dict)

这是我的订单模型

class ProducInBasket(models.Model):
    session_key                         = models.CharField(max_length=128, default=None)
    order                               = models.ForeignKey(Order, blank=True, null=True, default=None)
    product                             = models.ForeignKey(Product, blank=True, null=True, default=None)
    count_of_goods                      = models.IntegerField(default=1)
    price_per_item                      = models.DecimalField(max_digits=10, decimal_places=2, default=0)
    total_price                         = models.DecimalField(max_digits=19, decimal_places=2, default=0)
    is_active                           = models.BooleanField(default=True)
    publish                             = models.DateField(auto_now=False, auto_now_add=True)
    timestamp                           = models.DateTimeField(auto_now=False, auto_now_add=True)


    def __str__(self):
        return "{0}:|:{1}".format(self.price_per_item,self.order)

    class Meta:
        ordering = ["-timestamp"]
        verbose_name = 'Product in Basket'
        verbose_name_plural = 'Products in Basket'

这是我的模板，位于URL basket_adding

<form class="form-group formselect" action="{% url 'basket_adding' %}"> {% csrf_token %}
                    <label>Quantity</label>
                      <select class="form-control litlwidth" id="sel1" >
                        <option value="1">1</option>
                        <option value="2">2</option>
                        <option value="3">3</option>
                        <option value="4">4</option>
                        <option value="5">5</option>
                        <option value="6">6</option>
                        <option value="7">7</option>
                        <option value="8">8</option>
                        <option value="9">9</option>
                        <option value="10">10</option>
                      </select>
                    <br>
                    <button id="submit_btn" class="cartadd morewidth"  title="Add to Cart" type="submit" >Add to Cart</button>
                    <p class="info hidden" data-product_id="{{ instance.id }}" data-product_name="{{ instance.name }}" data-product_price="{{ instance.price }}"></p>

                </form>

这是带有ajax的jQuery代码

$(document).ready(function() {

    var newcount                = 0;
    var allprice                = 0;
    var btnn                    = $("#submit_btn");

        form.on('submit', function(e) {
        e.preventDefault();
        var product_id          = $(".info").data("product_id");
        var product_name        = $(".info").data("product_name");
        var price               = $(".info").data("product_price");
        var quantity            = $("#sel1").val();
        var full_price_per_item = (price * quantity)
        newprice                = allprice + (price * quantity );
        allprice                = newprice
        newcount++;
        $(".count").html(newcount);
        $("#price").html(newprice);

            },
        });

您使用的namespace是订单应用的网址。您必须将其提供namespace给url标记。

{% url 'orders:basket_adding' %}
#       \____/ \___________/
#         |          |
#     namespace   url name
