# URL slug (`url_slug`)

> **Draft.** Draft records have not been reviewed yet and may be incomplete or wrong; do not treat them as authoritative for legal or compliance decisions.

Readable part of a page URL that names an article, post or product, made from its title: lowercase letters and digits joined by hyphens, such as hello-world in example.com/2024/hello-world. WordPress and most CMS build slugs this way; Django also allows underscores and capital letters, and some sites keep non-Latin letters percent-encoded. The regexp accepts the usual form with at least one hyphen: a one-word slug such as about cannot be told apart from an ordinary word. Field names are slug, url_slug, post_name and permalink.
