Controller Filters

The Rails REST implementation dictates the default seven actions for your controllers, but frequently we want to share functionality across multiple actions or even across controllers. Controller filters are the easiest way to do that.

Before, After, and Around

There are three types of filters implemented in Rails:

a before_filter runs before the controller action
an after_filter runs after the controller action

	class Spiderman {
	lookOut() {
	alert('My Spider-Sense is tingling.');
	}
	}

	let miles = new Spiderman();
	miles.lookOut();

	// Top level App component
	import React from "react";
	import { ProvideAuth } from "./use-auth.js";

	function App(props) {
	return (
	<ProvideAuth>
	{/*
	Route components here, depending on how your app is structured.
	If using Next.js this would be /pages/_app.js

	console.log('Loading event');

	// Twilio Credentials
	var accountSid = '';
	var authToken = '';
	var fromNumber = '';

	var https = require('https');
	var queryString = require('querystring');

	#add 'node_modules' to .gitignore file

	git rm -r --cached node_modules
	git commit -m 'Remove the now ignored directory node_modules'
	git push origin <branch-name>

	function convertMiliseconds(miliseconds, format) {
	var days, hours, minutes, seconds, total_hours, total_minutes, total_seconds;

	total_seconds = parseInt(Math.floor(miliseconds / 1000));
	total_minutes = parseInt(Math.floor(total_seconds / 60));
	total_hours = parseInt(Math.floor(total_minutes / 60));
	days = parseInt(Math.floor(total_hours / 24));

	seconds = parseInt(total_seconds % 60);
	minutes = parseInt(total_minutes % 60);

	# install Command Line Tools for Xcode (*** if not yet!)

	#Install Homebrew
	$ ruby <(curl -fsSkL raw.github.com/mxcl/homebrew/go)

	# Add Homebrews binary path to the front of the $PATH
	$ echo "export PATH=/usr/local/sbin:$PATH" >> ~/.bash_profile
	$ source ~/.bash_profile

	# checar instalação do homebrew e possíveis pendências:

	for (var i=1; i <= 20; i++)
	{
	if (i % 15 == 0)
	console.log("FizzBuzz");
	else if (i % 3 == 0)
	console.log("Fizz");
	else if (i % 5 == 0)
	console.log("Buzz");
	else
	console.log(i);
