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.
# How to perform a release with git & maven following the git flow conventions | |
# ---------------------------------------------------------------------------- | |
# 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 |
