How to deploy Ruby Functions/ Apps with AWS Lambda

I followed this tutorial about getting started with Ruby on Lambda.

Nothing really happened as mentionned in the tutorial because many surprises occurred along the way :)

This tutorial is basically in 3 parts:

Creating a Hello World example
Including dependencies

Useful tools in case I have to setup a environment on a new machine

Octotree

Browser extension (Chrome, Firefox, Opera and Safari) that displays a code tree on GitHub

Notification Preview Github

Browser extension - Preview your notifications without leaving the page

How to read static fields from an APK

First install apktool

brew install apktool

Second run the command

apktool d PATH_TO_THE_APK_FILE

I am trying to run a very simple query on Postgres.

SQLite3

With Sqlite3, this query works perfectly:

>> SELECT DISTINCT "users".* FROM "users" INNER JOIN "comments" ON "comments"."user_id" = "users"."id" ORDER BY "comments"."rating" ASC

ActiveRecord advanced query

☀️ postgresql: has_many & distinct.

What happens in DB ?

Rails app

I created a rails app with models like so:

Connect DB to a Ruby Project and play with queries in console

I already had a ruby project, and there are few things I wanted to try to test some ActiveRecord queries. First I implemented a small script (see here ) But it was not easy to play with classes as I had to run the full script (gem installs, models definitions etc.).

I was looking a way to interact directly with the dabase in console.

Models

errors.details is `{ error: blank }` on belongs_to validation

With Rails 5, there is a validation on belongs_to association.

Actual behavior

If you have:

	HOT_DEPARTMENTS = ["Aisne", "Alpes-Maritimes", "Essonne", "Eure", "Hauts-de-Seine", "Nord", "Oise",
	"Paris", "Pas-de-Calais", "Seine-et-Marne", "Seine-Saint-Denis", "Seine-Maritime", "Somme",
	"Val-de-Marne", "Val-d’Oise", "Yvelines"]

	def please_explain(living_department:, reason_to_get_out:)
	if HOT_DEPARTMENTS.include?(living_department)
	distance_rule = reason_to_get_out.include?("*") ? "not " : ""
	return "You need an attestation & you're #{distance_rule}limited by the 30km rule"
	else
	if Time.now.hour.between?(9, 19)

	# frozen_string_literal: true

	begin
	require "bundler/inline"
	rescue LoadError => e
	$stderr.puts "Bundler version 1.10 or later is required. Please update your Bundler"
	raise e
	end

	gemfile(true) do

	# frozen_string_literal: true

	begin
	require "bundler/inline"
	rescue LoadError => e
	$stderr.puts "Bundler version 1.10 or later is required. Please update your Bundler"
	raise e
	end

	gemfile(true) do
