Your First Template
Part of the Django Basics section of Coddy's Django journey. Lesson 11 of 23.
The home page's HTML has grown too long for a Python string. Django keeps HTML in a template, a file the view renders. A shop's cart view:
from django.shortcuts import render
def cart(request):
return render(request, "shop/cart.html")render() reads the template, fills it in and returns an HttpResponse. Django looks for "shop/cart.html" in the templates/ folder of every app in INSTALLED_APPS, in settings.py. So two things must be right:
- the app is in
INSTALLED_APPS; - the file is at
shop/templates/shop/cart.html. The repeatedshopkeeps it apart from another app'scart.html.
Miss either and the page crashes with TemplateDoesNotExist, listing every folder Django searched. The {% url %} tag in home.html builds the About link; a later lesson explains it.
Challenge
EasyThe home page's HTML is ready in menu/templates/menu/home.html. Make the home view render it.
- In
mysite/settings.py, add"menu"toINSTALLED_APPS. Django finds templates only in apps listed there. - In
menu/views.py, importrenderfromdjango.shortcutsand replace thehomeview'sreturnline so it renders"menu/home.html".
Press Run: the site's title bar reads Corner Café.

"latte": {"name": "Latte", "price": 3.5, "description": "Espresso with lots of steamed milk."},
"flat-white": {"name": "Flat White", "price": 3.75, "description": "Espresso with a thin layer of silky milk."},
"hot-chocolate": {"name": "Hot Chocolate", "price": 3, "description": "Dark chocolate melted into warm milk."},
}
def home(request):
about_url = reverse("menu:about")
return HttpResponse(
"<h1>Welcome to Corner Café</h1><p>Fresh coffee and cake every day.</p>"
f'<a href="{about_url}">About us</a>'
)
def about(request):
return HttpResponse("Corner Café opened in 2026.")
def hours(request):
return HttpResponse("Open every day from 8:00 to 18:00.")
def contact(request):
return HttpResponse("Write to us at hello@cornercafe.example.")
def table(request, number):
return HttpResponse(f"<h1>Table {number}</h1>")
def drink(request, slug):
if slug not in DRINKS:
raise Http404(f"No drink called {slug}")
item = DRINKS[slug]
return HttpResponse(f"<h1>{item['name']}</h1><p>{item['description']}</p>")
def order(request):
size = request.GET.get("size", "medium")
if size not in ["small", "medium", "large"]:
size = "medium"
return HttpResponse(f"You ordered a {size} coffee.")
