Listing movies added to the cart

To allow us to list movies added to the cart, we will follow the next steps:

1. Configure the cart index URL.
2. Define a utils file.
3. Define a filter.
4. Define an index function.
5. Creating the cart.index template.
6. Updating the add_to_cart function.
7. Adding a link in the base template.

Configuring cart index URL

In /cart/urls.py, add the next path by adding the 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'),
]

We defined a '' path but remember that the project-level URL file defined a /cart prefix for this file. So, if a URL matches the /cart path, it will execute the index function defined in the views file. We will implement the index function later.
