- 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 therails 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

It's a common misconception that [William Shakespeare][1] and [Miguel de Cervantes][2] died on the same day in history - so much so that UNESCO named April 23 as [World Book Day because of this fact][3]. However because England hadn't yet adopted [Gregorian Calendar Reform][4] (and wouldn't until [1752][5]) their deaths are actually 10 days apart. Since Ruby's Time
class implements a [proleptic Gregorian calendar][6] and has no concept of calendar reform then there's no way to express this. This is where DateTime
steps in:
>> shakespeare = DateTime.iso8601('1616-04-23', Date::ENGLAND)
=> Tue, 23 Apr 1616 00:00:00 +0000
>> cervantes = DateTime.iso8601('1616-04-23', Date::ITALY)
=> Sat, 23 Apr 1616 00:00:00 +0000

Tell vim to use the system clipboard:
