Django Shopping Cart
====================
Django Shopping Cart is a Django app to store product in cart.
Detailed documentation is in the "docs" directory.
Quick start
-----------
1. Add "cart" to your INSTALLED_APPS setting like this::
INSTALLED_APPS = [
...
'cart',
]
Add below line to settings context_processor::
'cart.context_processor.cart_total_amount'
CART_SESSION_ID = 'cart'
2. You can use the urls in following way::
from django.urls import path
from . import views
urlpatterns = [
path('cart/add/<int:id>/', views.cart_add, name='cart_add'),
path('cart/item_clear/<int:id>/', views.item_clear, name='item_clear'),
path('cart/item_increment/<int:id>/',
views.item_increment, name='item_increment'),
path('cart/item_decrement/<int:id>/',
views.item_decrement, name='item_decrement'),
path('cart/cart_clear/', views.cart_clear, name='cart_clear'),
path('cart/cart-detail/',views.cart_detail,name='cart_detail'),
]
5. You should have a Product model & Below field is mandatory
name = models.CharField(max_length=255)
image = models.ImageField(upload_to='products/')
price = models.FloatField()
4. Then views.py should like like this::
from django.shortcuts import render, redirect
from store.models import Product
from django.contrib.auth.decorators import login_required
from cart.cart import Cart
@login_required(login_url="/users/login")
def cart_add(request, id):
cart = Cart(request)
product = Product.objects.get(id=id)
cart.add(product=product)
return redirect("home")
@login_required(login_url="/users/login")
def item_clear(request, id):
cart = Cart(request)
product = Product.objects.get(id=id)
cart.remove(product)
return redirect("cart_detail")
@login_required(login_url="/users/login")
def item_increment(request, id):
cart = Cart(request)
product = Product.objects.get(id=id)
cart.add(product=product)
return redirect("cart_detail")
@login_required(login_url="/users/login")
def item_decrement(request, id):
cart = Cart(request)
product = Product.objects.get(id=id)
cart.decrement(product=product)
return redirect("cart_detail")
@login_required(login_url="/users/login")
def cart_clear(request):
cart = Cart(request)
cart.clear()
return redirect("cart_detail")
@login_required(login_url="/users/login")
def cart_detail(request):
return render(request, 'cart/cart_detail.html')
5. In the template you can use the url in folowing way::
<a href="{% url 'cart_add' product.id %}">Add To Cart</a>
<a href="{% url 'cart_clear' %}">Clear Cart</a>
<a href="{% url 'item_increment' value.product_id %}">Increament</a>
<a href="{% url 'item_decrement' value.product_id %}">Decrement</a>
6. To view the cart detail page use the below code
{% load cart_tag %}
Total Length :: {{request.session.cart|length}}
Cart Detail::
{% for key,value in request.session.cart.items %}
{{value.name}}
{{value.price}}
{{value.quantity}}
{{value.image}}
Total {{ value.price|multiply:value.quantity }}
{% endfor %}
