When to use slug field and query string

Question

I am new in web development in django i don't know when to use slug field and when to use query string parameters in the url.Can anyone suggest me practical differences between them.

Answer 1

Using slugs keep urls simple and clean, thereby easy to remember. Consider the following example:

example.com/post/hello-world/

v/s

example.com/?post=hello-world

Obviously, first one is cleaner.

But query string parameters have their uses too. For example, when you search for an object.

example.com/search/?q=hello-world

or when you need to pass multiple parameters

example.com/search/?q=hello+world&lang=en&something=else
