Adding an audit log to your Rails app

If you have any sort of administrative interface on your web site, you can easily imagine an intruder gaining access and mucking about. How do you know the extent of the damage? Adding an audit log to your app is one quick solution. An audit log should record a few things:

controller entry points with parameter values
permanent information about the user, like user_id
transient information about the user, like IP and user_agent

Using the Rails framework, this is as simple as adding a before_action to your admin controllers. Here’s a basic version that I’m using in production.

How we incorporate next and cloudfront (2018-04-21)

Feel free to contact me at [email protected] or tweet at me @statisticsftw

This is a rough outline of how we utilize next.js and S3/Cloudfront. Hope it helps!

It assumes some knowledge of AWS.

Terminal Colors

There exists common confusion about terminal colors. This is what we have right now:

Plain ASCII
ANSI escape codes: 16 color codes with bold/italic and background
256 color palette: 216 colors + 16 ANSI + 24 gray (colors are 24-bit)
24-bit true color: "888" colors (aka 16 milion)

The experience of using Node.JS with TypeScript, ts-node, and ESM is horrible.

There are countless guides of how to integrate them, but none of them seem to work.

Here's what worked for me.

Just add the following files and run npm run dev. You'll be good to go!

	# post_serializer.rb

	class PostSerializer < ActiveModel::Serializer
	has_many :comments

	attributes :id, :title, :content
	end

	# comment_serializer.rb

	source "https://rubygems.org"

	gem "roda"
	gem "http", "~> 3.3"
	gem "rest-client"
	gem "httparty"
