alias_method_chain was deprecated in Rails 5.0 and removed in 5.1, in favor of Module#prepend. When upgrading a Rails application or gem that uses this method, a bit of restructuring is required.
Our Build Process
When building out projects we take a modular approach. We start with a "guidelines" page featuring each of the elements of the site individually before we place content. Doing this allows us to see that everything is consistent in style and feels cohesive. New site elements can quickly be compared to the existing styles, allowing expansion of site functionality while maintaining the brand. Once this is complete, any developer can quickly access the elements from this page and expedite page construction with well managed and consistently designed code. The page also gives clients a page they can access to reference for any marketing goods, and be customized to be used as a full company style guide if needed.
