Ever needed a URL for a title of an article, event, etc. in your Rails app? Rails
provides a free method for creating this type of slug:
You can call the method, which downcases, hyphenates, transliterates, and removes punctuation as:
> "Need a Slug?".parameterize => "need-a-slug"
It’s great for creating URLs, but remember that it’s not unique, so two strings can return the same parameterized output and cause issues if it’s used naïvely:
> "Need a Slug?".parameterize => "need-a-slug" > "Need a slug.".parameterize => "need-a-slug"
It’s also useful if you need to quickly grab a slug from a string outside a Rails app. I just used it to post an event with the parameterized path of the event’s title.
$ heroku run console > "Title of my Meetup, which was pretty long".parameterize => "title-of-my-meetup-which-was-pretty-long"
Use it in good health.
