Я получаю следующую ошибку после добавления href="{% url 'cart-add' product.id %}"
к кнопке добавления в корзину в моем product.html
файле:
NoReverseMatch at /3/
Reverse for 'cart-add' with arguments '('',)' not found. 1 pattern(s) tried: ['cart\\/add\\/(?P<product_id>[0-9]+)\\/$']
Я считаю, что это проблема или настройки пути URL, но я не знаю, как ее решить. В случае, если есть соответствующие файлы, которые я пропустил здесь, вот мой github: https://github.com/sebapaik/django-shop
Мой файл product.html выглядит следующим образом:
{% extends "shop/base.html" %}
{% block content %}
<div class="container">
<div class="row">
<div class="col-lg-4">
<img class="img-thumbnail" src="{{ object.imageurl }}" alt="">
</div>
<div class="col-lg-8">
<h2>{{ object.brand }} {{ object.pname }}</h2>
<p>${{ object.price }}</p>
<p>{{ object.description }}</p>
**likely the problem below**
<button class="btn" style="background:#f0c14b; border-color:#a88734;" href="{% url 'cart:cart-add' product.id %}">Add to cart</button>
</div>
</div>
{% endblock content %}
Мой проект / urls.py (main) выглядит следующим образом:
from django.contrib import admin
from django.urls import path, include
from django.conf import settings
from django.conf.urls.static import static
urlpatterns = [
path('admin/', admin.site.urls),
path('', include('shop.urls')),
path('cart/', include('cart.urls')),
]
Мой магазин / urls.py выглядит так:
from django.urls import path
from .views import ProductListView, ProductDetailView
from . import views
urlpatterns = [
path('', ProductListView.as_view(), name = 'shop-index'),
path('<int:pk>/', ProductDetailView.as_view(), name = 'shop-product'),
]
Моя корзина / urls.py выглядит так:
from django.urls import path
from . import views
urlpatterns = [
path('add/<int:product_id>/', views.add_cart, name='cart-add'),
path('', views.cart_detail, name='cart-detail'),
]
Мой файл settings.py выглядит так:
