Removing movies from the cart

To remove movies from the cart, we will follow the next steps:

1. Configure a clear URL.
2. Defining a clear function.
3. Updating the cart.index template.

Configuring clear URL

In /cart/urls.py, add the next path by adding the following lines in bold:

from django.urls import path
from . import views
urlpatterns = [
    path('', views.index, name='cart.index'),
    path('<int:id>/add/', views.add, name='cart.add'),
    path('clear/', views.clear, name='cart.clear'),
]

We define a cart/clear/ path that will execute the clear function defined in the views file. We will implement the clear function later.

Defining clear function

In /cart/views.py, add the following lines in bold at the end of the file:

…
def clear(request):
    request.session['cart'] = {}
 &...
