TemplateView และ get_context_data

TemplateView is a generic CBV whose only job is to render a template. It is the simplest class-based view you will use.

You tell TemplateView which file to render with the template_name attribute. No get method needed for a plain page.

Add it to urls with as_view(), just like any CBV. That one line gives you a fully working page.

A static page is fine, but usually you need context: data your template can display. CBVs provide a clean hook for that.

The get_context_data method builds the dictionary passed to your template. Override it to add your own values.

Start by calling super() to get the default context, then add to it. Skipping this can drop data Django expects.

After super(), insert any keys you need into the context dict. The template reads them by name.

In the template, reference a context key with double braces. Whatever you put under year appears where you write it.

The kwargs argument holds values captured from the URL, like an id. You can read them while building context.

Compared to a function view, TemplateView removes the repetitive render call. You declare the template once and add only the data.

TemplateView plus get_context_data is the pattern you will reach for whenever a page needs a template and a bit of dynamic data.

Which method do you override to add data for a TemplateView?

You learned TemplateView: set template_name to render a page, and override get_context_data, calling super first, to pass data along. ✨
