Cheat Sheet: Simple Authentication in Rails 6 with has_secure_password

The goal of this cheatsheet is to make it easy to add hand-rolled authentication to any rails app in a series of layers.

First the simplest/core layers, then optional layers depending on which features/functionality you want.

Setup

• Add a new worker to your Procfile. In this gist I used reporter
• Add the Heroku Platform gem to your Gemfile
• Create the HerokuReporterDyno module in lib or any other auto-loadable path
• Create two jobs. A caller (Reporting::GeneratorJob) and a runner (Reporting::RunnerJob)
• Deploy
• Once deployed, log into Heroku and change the newly added reporter dyno to a Performance M or Performance M dyno

How this all works

@function hsb($hue, $saturation, $brightness, $alpha: 1, $hsl-saturation: '') {
  @if $brightness == 0 {
    @return hsla(0, 0, 0, $alpha);
  } @else {
    $hsl-lightness:  (2 - $saturation / 100) * ($brightness / 2);
    $hsl-saturation: ($brightness * $saturation) / if($hsl-lightness < 50, $hsl-lightness * 2, 200 - $hsl-lightness * 2);
    @return hsla($hue, $hsl-saturation, $hsl-lightness, $alpha);
  }
}
