التقاط معاملات URL

Many pages depend on a value in the URL, like a product id. Django lets you capture that value and pass it straight to your view.

You capture a piece of the URL with angle brackets. Whatever is inside becomes a named argument for your view.

The word before the colon is a converter. It both matches a pattern and converts the captured text to the right Python type.

The int converter matches digits and hands your view a real integer, not a string. Perfect for numeric ids.

The slug converter matches letters, numbers, hyphens, and underscores. It is ideal for readable, SEO-friendly URLs.

The captured name becomes a parameter in your view, right after request. The names must match exactly.

The name in the URL and the view argument must be identical. If the URL says id, your view must accept id too.

Beyond int and slug, Django ships str, uuid, and path converters. Each matches a different shape of value.

If you skip the converter, Django uses str. It matches any text except a slash, which keeps segments separate.

You can capture several values in one route. Each becomes its own keyword argument in the view, in order.

If a URL value does not fit the converter, the route simply does not match. Django moves on or returns a 404.

Consider which converter fits a numeric id.

Use angle brackets with a converter to capture URL values. The view receives them by name, typed and ready to use. ✨
