1. What is Rails? Rails is a web application framework designed to work with the Ruby programming language. Sound like mumbo jumbo?! I know! Here’s the BIG idea: there is a programming language called Ruby. It’s super fun to write. In fact, the guy who first created it said that his major motivation when writing the language was to design a programming language that would make programmers happy. Nice, right? Let me give you an example. If I want to print something to the screen in PHP I need to write: echo “Hello World”; Notice the semi-colon? And what does echo even mean?!! On the other hand if I wanted to do the same thing in Ruby alls I would write is: puts “Hello World” No semi-colon, and puts may be a little… juvenile, but it makes more intuitive sense to me than echo. Seriously, when you spend hours and hours a day writing code, it’s the little things that make a HUGE difference. So, anyways, the only problem with Ruby was that it’s not designed for use on the Web. Like…you couldn’t really use it to make websites, per se. That is until… Rails! I am not sure if Rails was the first web framework for Ruby but it’s DEFINITELY the most popular. What Rails does is provide all this fancy scaffolding and stuff to make it possible to write a Ruby application and have it be a website. This sounds really abstract when you say it here, but it’s basically like this: if I were to write puts “Hello World” in an HTML document, you would just see the whole...
It’s no secret that we love Ruby on Rails at Planet Argon. We’ve been part of the community for 13 years, and have built over a hundred applications using this framework since then. But just because it’s our framework of choice doesn’t mean it’s the right choice for your business. Over the years, we’ve had several companies approach us about their existing Ruby on Rails application, or with the idea of creating a new app in Rails, that we’ve directed away from this framework. In these situations, we could have pitched a maintenance or new build retainer. And if we weren’t looking out for these companies’ best interest, and instead only cared about making more money, that’s surely what we would have done. But as the experts in our field, it’s also our responsibility to educate companies on the smartest decision for their company – even if it means they don’t become a client of ours in the process (I think there’s a Spiderman reference in there somewhere about power and responsibility…). The reasons that Ruby on Rails is not a good fit varies depending on the company’s situation. Here’s one example where we turned a company away from a custom Ruby on Rails app, why we did it, and what we pointed them toward instead. A Mid-Size E-Commerce Website: Queen Bee Creations A few years ago, a local Portland-based bag and accessory company – Queen Bee Creations contacted us about their custom Ruby on Rails e-commerce application. They told us a story we’re very familiar with and have heard again and again: the freelance Rails developer who created and maintained their app was leaving...
What is Live Templates and why use it for Ruby on Rails Live Templates (aka Code Snippets in many text editors) is a simple solution allowing you to generate frequently-used custom code constructs, and quickly insert them in the editor. While RubyMine has a built-in set of keywords for Ruby and Rails, and provides autocompletion for them, there are cases when using shortcuts is more preferable. In the case of Ruby on Rails development, this is especially applicable to HTML and ERB tags. As you probably know when you start typing <% in .html.erb files, the IDE suggests inserting the whole tag, and puts the caret right inside: But there are alternatives that you may find more convenient, especially if you are used to the default shortcut ⇧⌘./Ctrl+Shift+. that inserts ERB expression printing tag <%= %>, which doesn’t have a similar version for the “non-rendering” Ruby code execution tag <% %>. This is exactly the kind of case where live templates come in handy because they allow you to create one. Here’s how: Go to Preferences / Settings | Editor | Live Templates. Choose Rails from the list of available language/markup templates, and hit + to add a new template: Then take the following steps: Create an abbreviation that you will type for a quick insertion in the editor (like erbext), and provide a description that will help you remember what a specific template does(F1). Type the code that should be generated in the Template text field. Specify where the cursor should be put after the template is inserted by typing $END$. In our case we want to have the caret right inside the tag. Finally, decide if you want to insert the tag with Enter, Tab, or Space, and choose in...

by Shishir Kakaraddi, Srinivas Raghunathan, Adam Gross and Ryan Johnston We are pleased to announce the open source release of Fast JSON API gem geared towards Ruby on Rails applications. Introduction Fast JSONAPI is aimed at providing all the major functionality that Active Model Serializer (AMS) provides, along with an emphasis on speed and performance, by meeting a benchmark requirement to be 25 times faster than AMS. The gem enforces performance testing as a discipline. Active Model Serializer is a great gem and Fast JSON API was inspired by it when it comes to declaration syntax and features. But, AMS begins to slow down when a model has one or more relationships. Compound document, AKA sideloading, on those models makes AMS slow down further. Throw in a need for infinite scroll on the UI, and AMS’s slowness starts becoming visible to users. Why optimize serialization? JSON API serialization is often one of the slowest parts of many well implemented Rails API’s. Why not provide all the major functionality that AMS provides and with great speed? Features: Declaration syntax similar to Active Model Serializer Support for belongs_to, has_many and has_one Support for compound documents (included) Optimized serialization of compound documents Caching Instrumentation with Skylight integration (optional) How do you write a serializer using Fast JSONAPI? We like the familiar way Active Model Serializers lets us declare our serializers. Declaration syntax of fast_jsonapi is similar to AMS. class MovieSerializer include FastJsonapi::ObjectSerializer attributes :name, :year has_many :actors belongs_to :owner, record_type: :user belongs_to :movie_typeend How fast is it compared to Active Model Serializers? Performance tests indicates a 25–40x speed gain over AMS, essentially making serialization time negligible on even...
