Those export paths would seem to hard wire Ruby versions. As Chris says you want to use something else to select Ruby versions. A very simple one is chruby. Doesn't seem to get much attention probably because it isn't as powerful as others.

Getting Started with Dev Containers: https://guides.rubyonrails.org/getting_started_with_devcontainer.html
Maybe because I'm not using VS Code, I had to do it differently

Your command will create an app named rails-version the 7.2.0 is ignored, at least on my computer. Here's what I did
$ gem install rails
$ rails -v # to confirm 7.2.0
$ rails new my_rails_7.2_app \
--css=bootstrap \
--database=postgresql \
--asset-pipeline=propshaft \
--devcontainer

Created an app. Many Bootstrap errors and warnings, but otherwise seems OK. But I shouldn't have had to do the first step using devcontainer, so I am doing something wrong.

I'm a very amateur Rails user and only have hobby apps with low usage. I'm willing to pay for simplicity. I was OK with Heroku and was able to move the Postgres database back and forth from my Mac to Heroku as needed and not too many problems deploying. I've had more trouble with Fly.io.
That said, any good comparison sources to recommend?

It sounds as if you want to be current. So you might focus on getting Rails 7 and Ruby 3 installed. 'nokogiri' has frequently caused me issues like this—I never quite know what got it working again. Search for how to install Rails using rbenv. I don't use rbenv but it seems to be the most commonly used so should be solid. Good luck.

One old set of notes said these two commands worked.
brew install libxml2
bundle config build.nokogiri --use-system-libraries --with-xml2-include=/usr/include/libxml2/

Maybe it's length:

Replying to self. I just copied the URL and got to the right page.

This walking through of how to set up AWS S3 was very helpful. I've done it before and sure I've made some (probably serious) errors.

How did you get to the Policy section on AWS?

As long as you use rails g stimulus new_controller_name updates index.js and create a controller.

@Stéphane Paquet Makes sense. Fight Bootstrap or find a predefined kit. The one thing I don't like is that the HTML gets messier or longer anyway. Maybe better if my editor could collapse the 'class' on demand.

Maybe not a good answer. I ran into a problem upgrading to 3.1.2 and just rolled back to 3.0.2. Not the same problem as yours. My thinking was I didn't need the latest and that eventually the problem would be fixed. And I was on Rails 7, so would assume fewer issues. My notes:

Downgraded to ruby-3.0.2 because of visit_Psych_Nodes_Alias': Cannot load database configuration: (Psych::BadAlias) error on launch (https://stackoverflow.com/questions/71191685/visit-psych-nodes-alias-unknown-alias-default-psychbadalias)

Not an answer, but I got it working by running rails assets:precompile. Shouldn't this be part of Profile.dev? or something like that?

Still curious about original question of how to see what is happening and what should happen.

I updated a Rails 6 app to Rails 7 and changed from Webpacker to esbuild/webpack. Added Stimulus, and after not getting controllers to work tried a basic hello_controller and then searched the application.js as seen in Chrome and no 'hello' or "Hello" I made a basic app to compare. I've toggled many settings and don't know where to look.

webpack.config.js are identical. hello_controller.js is identical.

Second the request for the "right" way to add another .css.

In particular I am using Leaflet.js and Leaflet adds some css.
I tried @import './node_modules/leaflet/dist/leaflet.css'; in application.bootstrap.scss, but it doesn't work. Also confusing that this file isn't named application.scss and then add the bootstrap specific css.

@PatJames
// /app/assets/stylesheets/application.scss
@import 'bootstrap';

// /app/assets/stylesheets/bootstrap.scss
@import 'bootstrap/scss/bootstrap';

// /app/javascript/application.js
// Entry point for the build script in your package.json
import "@hotwired/turbo-rails"
import "./controllers"
import * as bootstrap from "bootstrap"

I have been looking at Rails 7 and am now working on trying to upgrade an app using importmaps. In other words I don't have a big app working with esbuild. My notes on say what I put in above is based on https://www.bootrails.com/blog/rails-7-bootstrap-5-tutorial/.

PS. I'm not hurrying waiting for more tutorials and discussions. I've got a dozen tabs already opened to dig through.

Can't help with that, but am looking more into fly.io. It sets up the Docker automatically. I am having trouble deploying and have to dig further. With a Postgres db appears to be ⅓ the price of Heroku. If that is the case I might keep my three toy apps going.

Great. Sets up Docker which I didn't want to get into, so that's a great help. Trying it. Looks like $7/month with a Postgres db.

mini_exiftool and exif gems for meta tags. I found exif less complete but faster. The gems use ExifTool (https://exiftool.org).

Read the history of JavaScript. It was written in two weeks (fact check needed) and it shows. But because browsers support it you can't change to another language for almost anything on the web. My simplified version.
