Explain why slugfield is needed in django?

Question

Django

Often in models I set a field called slug, I don’t quite understand why it is needed, tell me please

Answer 1

For example, you have articles on the site. And you want links like /pages/novaya-statya/ , the article is called NEW ARTICLE, and the link is novaya-statya. That's what it's for. By the way, see also that ideally they (slugfields) should be unique.

Answer 2

Thank you all understood =)
