I’m trying to migrate my models to be dumb data bags that have some useful state altering methods. I’ve found that using query objects, I was able to reduce the complexity of some of my models and controllers. The Problem My User model is gigantic. It’s well over 600 LOC, and it’s growing at a scary rate. Testing is becoming a nightmare because of all the methods. A few methods I have realized, I could remove completely and extract them into query objects....
Recently I’ve been playing with Ruby’s class_eval and define_method to append methods to an object. Meta programming is something new for me and I had a problem that would benefit from using some of Ruby’s cool features. The Problem There was a model that had 6 fields that needed to be generated at some point in time. Some fields had to be unique and others had to be generated a bit differently....
One day I found myself riding in a car with my family and it was a long road trip, with little to no internet and realized that my tests required internet connectivity. I was also heavily dependent upon code examples that I could find. I’ve been absolutely horrible with testing my code. I would write code, test it out in the ruby console and then push it live. It felt like I was moving fast....
I despise consuming 3rd party APIs for one reason, speed. Many of the APIs I have to consume on a daily basis, respond slower than it would take to deliver an email. But, their integration with our application is absolutely critical. They are so critical infact, that if an error should happen during any point of the commissioning, then I need to be notified and or the job needs to be reattempted at a later date....
I have been staring at Ruby for so long that I have become disgusted with low level languages like C or C++. Mid level languages like Java still make me cringe when I look at them. As I sit and write code in Ruby that runs on a terribly slow VM I begin to think. Why don’t high level languages like Ruby or Python compile into assembly level code like C does when it is compiled?...
When I am writing a Rails application it starts out simple with a few if @something.save lines that are pretty self explanatory. Then the application grows and starts to become hairy. Take my contrived example with a grain of salt as I can’t show you production code that I am using. # app/controllers/widgets_controller.rb class WidgetsController < ApplicationController # # Other methods go here # def something # Maybe we handle the update in a special way widget = Widget....
