Red-green-refactor is an important concept in TDD when you are using tests to drive your code and I’ll use an example to demonstrate how this works. First I start off with a series of descriptions about what I want my code to do. As an example, I have a todo list that has a name and description and I want to write a method that checks if my object only has a name defined. So my initial test setup would be:

GitHub Flow is a workflow guideline for how to work with GitHub and revolves around the idea of deploying regularly to GitHub. This ensures that it is very difficult, if not impossible, to introduce a large number of significant bugs. Additionally it enables me to quickly address issues of all kinds.

When talking about testing there are three main techniques to talk about:

You’ll hear it lots, fat models/skinny controllers but I was working on a project recently where my controller code was putting on a bit of weight!

Building my own application from scratch has been an amazing experience and there’s no way I’d have progressed this fast without the guys from Tealeaf Academy and a local developer I’ve been working with.

In order to do this I will need phone and pin columns added to the users table with a migration. The logic for authentication will be as follows:

Using ajax in rails is similar to how I used method: 'post' for the vote up/down links in order to generate a form on the fly. In this case, using remote: true generates html with a date-remote call. Javascript in rails is looking for that data-remote call and then attaches itself to the element and converts the given link to an ajax call. An example using my code is helpful to explain:

If I had another project that I wanted to add the functionality of voting to then I would be better making a Gem. To begin with I need to install gemcutter. Next I have to make sure I exit my current project folder because the Gem is a completely separate project. Then create a new project called voteable-gem and then it needs a gem specification file which I call voteable.gemspec and it will look as follows:

In a previous post I wrote a post about how to do this and this post goes through some more ways to achieve the same result in a slightly more succint way. In order to use a module in this case I have to define a path in rails in which to find the module. I need to go to application.rb and add in this line of code:

I had a case in my postit application where I needed to add voting for both comments and posts. This required some code in my models for Post and Comment to count the votes:
