Turbo Will Call Stimulus `connect()` Twice

Tuesday, September 26, 2023

When you click a link to return to a page, or use your browsers back button to return to a page Turbo will render a cached preview of the page. It will then fetch an updated version of the page. If you have a stimulus controller on the page what will happen is the controller is initialized twice. The initial cached version will load the controller and fire off the connect() method, then the page is refreshed via Turbo, the controller is disconnected, then reconnected when the DOM is updated from the Turbo update.

The difference between length, size, and count in Ruby on Rails

Tuesday, September 20, 2022

But I wanted to really understand so I dug into the API docs.

Deploying a Simple Rails App with Ansible

Wednesday, March 10, 2021

Ruby on Rails is quickly becoming my framework of choice for my personal websites and projects. It's a pleasure to work with and has been easy to learn. But no framework is without its challenges. One of those challenges is of course deploying the app to a server. There are a lot of options for hosting and deploying a Rails app. But, I like to run my own servers which means I have to also take care of deploying to those servers.
