Socket

[Document on ruby-doc.org] [ruby_doc]

Introduction

Ruby provides a standard library Socket for networking programming in lower layer, such as TCP and UDP. There are also other libraries for application layers like HTTP, FTP and TELNET, they are not included in this tutorial.

Resourceable module

Revisiting a Rails project from when I started developing, I wanted to figure out how to really DRY my controllers out—without making them unreadable by doing half/all of the work in a before_action. (I've used CanCanCan's load_resource in the past. That and some other gems I looked at are a little too DRY for what I want.)

So I wrote this module to encapsulate the business logic of finding the record and loading the params data within an Accessor object. It's not meant to cover all cases, but I'm pretty happy with it.

I have it set up with controller tests in a scaffolded app here.

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.
