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.

TOC

• Installing Postgres & PostGIS
• Using Postgres on the command line: PSQL
• Importing Data into Postgres
• Exporting Data from Postgres

// Simplified Additive Particle shader. Differences from regular Additive Particle one:
// - no Tint color
// - no Smooth particle support
// - no AlphaTest
// - no ColorMask

Shader "Mobile/Particles/Additive" {
Properties {
    _MainTex ("Particle Texture", 2D) = "white" {}
}
