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.

| # Finding the next version: you can see the next version by looking at the | |
| # version element in "pom.xml" and lopping off "-SNAPSHOT". To illustrate, | |
| # if the pom's version read "0.0.2-SNAPSHOT", the following instructions would | |
| # perform the release for version "0.0.2" and increment the development version | |
| # of each project to "0.0.3-SNAPSHOT". | |
| # branch from develop to a new release branch | |
| git checkout develop |
