Prelude

I. Preface and Motivation

This guide was written because I don't particularly enjoy deploying Phoenix (or Elixir for that matter) applications. It's not easy. Primarily, I don't have a lot of money to spend on a nice, fancy VPS so compiling my Phoenix apps on my VPS often isn't an option. For that, we have Distillery releases. However, that requires me to either have a separate server for staging to use as a build server, or to keep a particular version of Erlang installed on my VPS, neither of which sound like great options to me and they all have the possibilities of version mismatches with ERTS. In addition to all this, theres a whole lot of configuration which needs to be done to setup a Phoenix app for deployment, and it's hard to remember.

For that reason, I wanted to use Docker so that all of my deployments would be automated and reproducable. In addition, Docker would allow me to have reproducable builds for my releases. I could build my releases on any machine that I wanted in a contai

Defining Many-to-Many Associations in Sequelize

Reference: Sequelize docs on association

Let’s say we have two models: Films and Festivals

We know that a film can be shown at many film festivals and that, conversely, a festival can show many films. This is what is known as a many-to-many relationship.

Knowing this, we can set up our associations:

	use aiken/hash.{Blake2b_224, Hash}
	use aiken/interval.{Finite, Interval, IntervalBound}
	use aiken/list
	use aiken/transaction.{ScriptContext, Spend, ValidityRange}
	use aiken/transaction/credential.{VerificationKey}

	type POSIXTime =
	Int

	type PubKeyHash =

	// App/utilities/AndroidFontFix.js

	import React from 'react';
	import { Platform, StyleSheet, Text } from 'react-native';
	import { getManufacturerSync } from 'react-native-device-info';

	# Usage:
	# aws cloudformation --region <region> create-stack --stack-name <stack name> --template-body file://vpc-fargate.yaml

	# This template will:
	# Create a VPC with:
	# 2 Public Subnets
	# 2 Private Subnets
	# An Internet Gateway (with routes to it for Public Subnets)
	# A NAT Gateway for outbound access (with routes from Private Subnets set to use it)
