How to Configure Selenium for Full Stack Integration Testing with Ruby on Rails

Knowing how to use testing frameworks is one of the most important skills any developer must learn. In particular with the Ruby programming language, testing is even more important because a compiler will not catch syntax errors or little slip ups! Such is life when using interpreted languages. Despite testing’s importance being obvious, it is surprising how many Ruby on Rails apps have deficient test coverage or no code coverage at all! Why is this?

Using Rationals in the Ruby Programming Language!

Ruby’s Standard Library is full of many Objects that ship with just about any Object Oriented programming language. We have String, Hash, Array, Integer, and Float. However, there are several more “niche” Objects that many code schools and programming books overlook. In this article, I’m going to show off one of Ruby’s lesser utilized Objects: the Rational Class. What are they and what can you use them to do?

Stripe Subscriptions with Koudoku

Recently we were working on a project in which we needed a subscription based payment system to manage different user plans. This was an MVP so we did not necessarily want to roll our own subscription system if we didnt have to. Enter Koudoku, a Rails based subscription engine that integrates into Stripe out of the box and uses Stripe Event to hook into Stripe’s beatifully simple subscription plan system.

Modeling Postgres Common Table Expressions and Window Functions with Rails and ActiveRecord

Over the course of my experience as a developer, I’ve often found that when things get complex - they get really complex. Often times the key to a solution isn’t finding the one thing that solves a problem, but rather the combination of different functionalities that ends up being the solution that works the best. In the case of one of our pro-bono projects, I had a particularly difficult problem that I needed to solve - and the solution that I arrived at involved a combination of Postgres’ Common Table Expressions, Window Functions, SearchLight, and Rails Query Scopes. What on earth was I trying to accomplish that could possibly elicit this witches brew of open source technologies? Simple: I needed to take user-supplied input, sanitize it, geocode it, then ensure that the result set did not contain duplicates. Each of the tools listed above contributed in some fashion to the working solution!

Simple Polymorphic Selects with Global IDs

In an app I was working on recently, there was a requirement for a document (these were agreements of one type or another) to have many parties. In turn each of these parties needed to have an owner—and here’s where things began to get a little more complex—the party owners could be one of several model types. Ugh. Building a working select box for this functionality was going to be a mess. Or that’s what I thought initially. That’s when I happened across a few blogs about using Global IDs in Ruby on Rails. The Global IDs module became an official part of Ruby on Rails with the release of version 4.2. This module only includes a few methods and the one I ended up using most often is #to_global_id.

Efficiently Architect Ruby on Rails Applications

It doesn’t take much reading in regards to rails before you hit the “Convention over configuration” line. In my early days of development I had little idea of what that meant, either in terms of implications or for concrete uses. Now when I see that, I immediately think of arranging files within your application, how everything has a place, and how putting things where they belong make it quick and therefore efficient to find the files that need to change, make those changes and then update specs or associated files easily. That’s less headaches, more features and happier client and developers at the end of the day.

Efficiently Develop Ruby on Rails Applications

Time is money. If this was a movie and I was a learned monk, I’d leave it at that, turn around and walk away into the mist, leaving you on a journey to figure out the full meaning and implications of that for yourself. But this is a brain dump of where I currently am in how I develop, so I’ll go into the details of what I do to insure my time is well spent.

Get Your Data to Glass 180x Quicker: How to Setup Clusterize.js with Rails and Coffeescript

Fast Server, Slow Browser

Here’s the situation: Your amazing developer team has rocked your world with caching and other optimizations to get data from your client’s Rails server over to the users’ browsers. Your monitoring shows requests that were taking a whole 80-90 seconds to serve are now only taking 1500ms (and all that time is actually spent transferring megabytes of html to the browser, actual data retrieval is ~10ms). These numbers come from a recent project I did for a client with production data. Now, to tackle the last piece of speeding it up… Chrome browser is taking MINUTES (6 minutes, actually) to fully build and render the page after it’s received the data. 100% unacceptable. Time to drop in some asynchronous data transferral and a specialized Javascript library to keep things performant on the client side!
