Friendly URLs

By default, Rails applications build URLs based on the primary key -- the id column from the database. Imagine we have a Person model and associated controller. We have a person record for Bob Martin that has id number 6. The URL for his show page would be:

/people/6

But, for aesthetic or SEO purposes, we want Bob's name in the URL. The last segment, the 6 here, is called the "slug". Let's look at a few ways to implement better slugs.

	// String utils
	//
	// resources:
	// -- mout, https://github.com/mout/mout/tree/master/src/string

	/**
	* "Safer" String.toLowerCase()
	*/
	function lowerCase(str) {
	return str.toLowerCase();
