Templates Hold Your HTML

A template is an HTML file with little placeholders. Your view fills those blanks with real data before it reaches the browser. 🎨

Meet the Context

The context is just a Python dictionary your view hands to the template. Its keys become the variables you can print inside the page.

context = {"name": "Ada", "count": 3}

render() Ties It Together

The render() shortcut takes the request, a template name, and a context, then returns a finished HttpResponse for you.

from django.shortcuts import render

A Tiny View That Renders

Here a view passes one value to a template. Notice how render() does all the loading and response work in a single line.

def hello(request):
    return render(request, "hello.html", {"name": "Ada"})

Printing a Variable

Inside the template you print a context value with double braces. Django swaps {{ name }} for whatever your view sent.

<h1>Hello, {{ name }}!</h1>

Where Templates Live

Django looks for templates in a templates folder, usually one per app. Keeping them there lets the loader find each file by name.

myapp/templates/myapp/hello.html

Namespacing Avoids Clashes

Nesting templates under an app-named subfolder is a namespace. It stops two apps from fighting over the same file name.

templates/blog/post.html

Dotted Access in Templates

The template language uses a dot for everything: dictionary keys, object attributes, and list items all read as value.key.

<p>{{ user.email }}</p>

Missing Keys Stay Quiet

If a context variable is missing, Django prints an empty string instead of crashing. This silent failure keeps pages from breaking on small gaps.

Passing Several Values

Your context can hold as many keys as you like, mixing strings, numbers, lists, and objects. The template reads each by its key.

return render(request, "page.html", {"posts": posts, "total": 5})

Templates Stay Logic-Light

Do heavy work in the view, not the page. The template should mostly display data, keeping presentation and logic comfortably separate.

Quick Check

Think about how data travels from a view to a page.

Recap: View to Page

You learned that render() joins a request, a template, and a context dict into one response, and that {{ }} prints those values. Next up: tags and filters.
