• You MUST NOT try and generate a Rails app from scratch on your own by generating each file. For a NEW app you MUST use rails new first to generate all of the boilerplate files necessary.
• Create an app in the current directory with rails new .
• Use Tailwind CSS for styling. Use --css tailwind as an option on the rails new call to do this automatically.
• Use Ruby 3.2+ and Rails 8.0+ practices.
• Use the default Minitest approach for testing, do not use RSpec.
• Default to using SQLite in development. rails new will do this automatically but take care if you write any custom SQL that it is SQLite compatible.
• An app can be built with a devcontainer such as rails new myapp --devcontainer but only do this if requested directly.
• Rails apps have a lot of directories to consider, such as app, config, db, etc.
• Adhere to MVC conventions: singular model names (e.g., Product) map to plural tables (products); controllers are plural.
• Guard against incapable browsers accessing controllers with `allo

Currency Format Input Field

Auto format currency input field with commas and decimals if needed. This is how I would personally expect one to work. Works left to right without forcing user to enter 00 cents if there is none. Text is automatically formatted with commas and cursor is placed back where user left off after formatting vs cursor moving to the end of the input. Validation is on KeyUp and a final validation is done on blur.

// This helper file provides a consistent API for testing Stimulus Controllers
//
// Use:
// import { getHTML, setHTML, startStimulus } from './_stimulus_helper';
// import MyController from '@javascripts/controllers/my_controller';
//
// beforeEach(() => startStimulus('my', MyController));
// test('should do something', async () => {
//   await setHTML(`<button data-controller="my" data-action="my#action">click</button>`);

To upgrade to Stimulus 3.0 and minimize the side effects of the npm package name change here is my suggestion

# add the proxy package
yarn add stimulus

# add the new @hotwired/stimulus package
yarn add @hotwired/stimulus

# add the dedicated package for the Webpack helpers
