Ruby on Rails Cheatsheet

Architecture

Create a new application

Install the Rails gem if you haven't done so before

%Q, %q, %W, %w, %x, %r, %s, %i

Perl-inspired notation to quote strings: by using % (percent character) and specifying a delimiting character.

Any single non-alpha-numeric character can be used as the delimiter, %[including these], %?or these?, %~or even these things~.

Strings

% or %Q

VSCode italic font settings

Add this to settings.json (cmd ,):

{
  "editor.fontFamily": "Operator Mono, Fira Code iScript, Menlo, Monaco, 'Courier New', monospace",
  "editor.fontLigatures": true,
  "editor.tokenColorCustomizations": {
    "textMateRules": [
      {

Phoenix 1.4 ships with exciting new features, most notably with HTTP2 support, improved development experience with faster compile times, new error pages, and local SSL certificate generation. Additionally, our channel layer internals receiveced an overhaul, provided better structure and extensibility. We also shipped a new and improved Presence javascript API, as well as Elixir formatter integration for our routing and test DSLs.

This release requires few user-facing changes and should be a fast upgrade for those on Phoenix 1.3.x.
