Problem

Installing mysql2 gem errors on MacOS Mojave.

Solution

Make sure openssl is installed on Mac via Homebrew.

I’m amazed by React and how it’s bringing happiness to our developer lives. I specially like the workflow that integrates Webpack + React + CSS Modules + Babel among other tools and preprocessors. That’s why Javier Jiménez and I are working together in a library called React Toolbox that we would like to show in a lightning talk at Reactive Conference.

The main idea is to create a set of React components implementing Material Design guidelines. There are already some libraries that solve a similar problem but our project is mostly focused on the workflow and best practices to create a tool everybody would want to use. Also, we are sticking to the design guidelines proposed by Google and embracing minimalism by generating the minimum possible amount of HTML and styles to get the best result. Our workflow includes among others:

Webpack.
ES6 with Babel

Migrating a Rails project from MySQL to PostgreSQL

This brief guide is written from my own experience with migrating a large (~5GB) MySQL database to PostgreSQL for a Rails project.

No warranties, guarantees, support etc. Use at your own risk and, as always, ENSURE YOU MAKE BACKUPS FIRST!

I chose [pgloader][1] because it's extremely fast. YMMV.

Replace mysql2 gem with pg in Gemfile.
Update config/database.yml for PostgreSQL. I used [Rails' template][2] as a starting point.

The problem

Using multiple namespaces will require to have also namespaces views. For exemple, if you have an Admin namespace, with a Admin::ProjectsController with a show action that also exists in non namespaced ProjecsController, you cannot render views/projects/show.html.erv from Admin::ProjecsController.

What we want to do

The researched behavior is to try to render the views/admin/projects/show.html.erb, and, if it doesn't exist, fallback to views/projects/show.html.erb

	# In our gemfile:
	# gem 'rubyzip'

	require 'zip'

	# private ?
	def process_and_create_zip_file
	# Simulation of an object with has_many_attached :documents
	job = Job.first.documents
	# Tmp folder to store the download files from S3

	#!/bin/bash
