I was always reasoning how I could resolve all the CodeClimate duplication messages for my controllers. I thought about a generic controller to resolve the issue, but I was always concerning about the best implementation.
Two weeks ago I was again overthinking a good solution and I just came up with the implementation published at SimpleController GitHub Repo.
Although there are up to now just very simple controller methods supported, I already could improve the CodeClimate rating of three controllers from C to A.
I appreciate any kind of feedback, either via mail or on Github.
