Ruby on Rails is great to give out detailed error messages. Additionally, there is a wealth of knownledge in the online community of other developers running into the exact same error and the reasons behind why they are occuring. Over the past couple months I have compiled 5 errors that I see most often.

If you have ever tried to write functional tests for a controller, you will know that they can be a little tricky.

Well, unfortunately in the Ruby community this has been a point of contention because no built-in function exists. We can however easily replicate the intended behavior through the clever usage of the enumerable sort method.

The Rails asset pipeline uses a feature called Turbolinks for serving faster CSS and JS assets to the browser. It works by using AJAX to re-load assets without refreshing the page. Unfortunately, it also can mess up scripts that work with the document ready event such as jQuery. The only way to make the assets work is with a hard refresh. Let's fix this.

I've always felt that getting up and running with a new web development project should be as easy as possible. A good example of this is a Rails app. As Ruby on Rails accomplishes a high degree of ease of use straight out of the box, this article will focus on setting up an automated testing environment and sprucing up your CSS with bootstrap-sass.
