The other day I was listening to the FullStackRadio episode 34 which is about dealing with dependencies in Active Record models. This is a very interesting topic and they suggest a few solutions for it. I liked the suggestions and I tried to implement it differently (first try and second try). After that, I decided to talk to my colleagues about the design implementations. And they asked “why not implementing it as a command?”. At first sight I was a bit reluctant, because I’m starting to think applications are getting more complex then it really needs. Then I decided to implement it and the end result was the best one to us. Let’s discuss it a bit.
