A Retrospective on Ruby in 2015. This article was peer reviewed by Thom Parkin and Fred Heath. Thanks to all of SitePoint’s peer reviewers for making SitePoint content the best it can be! We’ve come to the end of 2015, which was a big year in Ruby. I thought it’d be a hoot to go back and look at some of the epics (major themes) of the year and the stories that comprised them. Kind of like a Agile process retrospective where I’m treating 2015 as a set of sprints and seeing how we did. In order to play out this contrived idea all the way, I will need to define the epics. I’d say that, almost every year, Ruby has the following major areas/epics/whatever where the community needs to be productive in order to consider that sprint/year a success: Improve the languageGrow the communityKeep up with the rest of the programming world Those are the epics I’ve defined.
Finally, any retrospective worth its weight in gems needs to look at what didn’t work. Improve the Language Ruby Battle of the Year Rails Off the Rails Grow the Community. Emphasized Insanity - Creating a Rails authentication system on Mongoid - Part 1. Preface A few days ago we started our first real all-MongoDB project at Nautilus6. Up until now we used Mongo only on small time projects, ones that hardly required any data storage at all so this is practically the first real project that we will try (and hopefully succeed) to deploy with Mongo as the data layer. Since we use Rails on this project (Duh) we had to choose between the existing MongoDB adapters for rails: MongoMapper – Which is pretty slick, has some plugin support but also replicates some of the familiar ActiveRecord functionality like: Dirty Attributes, Dynamic finders and magic timestamp attributes.
Mongoid – the new child, missing some features from MM (dirty attributes, dynamic finders for example) but does cover some ActiveRecord wonders MM doesn’t: Versioning, named scopes and better validation options. MongoId also supports a master/slave infrastructure which might be useful. We decided to go with Mongoid due to the fact that i kind of like the code base better. Yay!

You were probably wondering how it is you send email using Ruby on Rails.
Here’s how you create an automated email system that sends a confirmation email to each new user that registers to your app: 1. First off, in bash, you must generate your mailer, which uses the Rails generate command (pretty much the same way you generate a controller or a model). Cd ~/my_rails_project rails generate mailer welcome_mailer bundle install 2. This is how your setup_mail.rb file should look like: /config/initializers/setup_mail.rb 3. We do that by creating a method in the recently created mailer, which we’ll name registration_confirmation: /app/mailers/welcome_mailer.rb class WelcomeMailer < ActionMailer::Base def registration_confirmation(user) mail :to => user, :from => "email@example.com", :subject => "Subject line" end end 4.
I did some digging, and it looks like Rails uses Rack::Utils’ parse_nested_query helper. Their documentation is somewhat less comprehensive than I’d hoped, so I experimented a bit to figure out what’s going on. Below are a few examples of what I discovered. I’ve broken the query strings onto multiple lines simply for readability. Simple Input If your fields are named without any brackets, Rails will assume you don’t have any fancy nested data structure. Querystring: Parsed data structure: Attributes of an Object Using square brackets to name attributes, you can nest attributes inside an object:

Visit the linked website for additional information about the individual strategies. If you have implemented a strategy and would like to link to it here, feel free! Provider Strategies These providers are meant to be used directly by developers to authenticate to various services. Official designates that the strategy is maintained by developers of the service itself. Please keep the list in alphabetical order. Developer Strategies These strategies are meant to be used by people building their own strategies to easily leverage open standards or other common authentication systems.

A quick reference guide for Ruby on Rails, containing the default directory structure, predefined variables, methods, reserved words and regular expression syntax. The Ruby On Rails cheat sheet is designed to be printed on an A4 sheet of paper and live by a developers desk, to make life a bit easier. A description of what is on the cheat sheet follows, or if you are impatient, you can go straight to the full size Ruby On Rails cheat sheet. I am no expert in Ruby, On Rails or off, so to ensure this cheat sheet was as useful as possible, I pestered the very helpful Amy Hoy of (24)Slash7 and David Heinemeier Hansson of Loud Thinking into giving me a hand.
Thanks, both of you - I appreciate it. Default Directory Structure Ruby on Rails by default uses a rather large selection of folders and files, organised into a directory structure. Pre-Defined Variables Ruby on Rails, like most languages, includes a large number of predefined variables. Reserved Words Regular Expression Syntax Methods Download.

About Ruby on Rails Ruby on Rails is an application stack that provides developers with a framework to quickly create a variety of web applications. Ruby on Rails does take a little while to install on a virtual server, but luckily there are a lot of helpful tools to make this process as easy as possible.
You can run this tutorial on your droplet as a user with sudo privileges. You can check out how to set that up here: Ubuntu Server Setup Step One— Install Ruby with RVM Before we do anything else, we should run a quick update to make sure that all of the packages we download to our VPS are up to date: sudo apt-get update Once that's done, we can start installing RVM, Ruby Version Manager.
If you do not have curl on your system, you can start by installing it: sudo apt-get install curl To install RVM, open terminal and type in this command: \curl -L | bash -s stable After it is done installing, load RVM.
