The recent series of videos on Is TDD Dead has led to many interesting discussions. One of these was an email exchange I had with my colleague Badri Janakiraman, who is a long-time ThoughtWorker with a lot of experience in Rails and other development stacks. We decided to video this conversation, as I thought some other people would enjoy it too. Our conversation looks at the Hexagonal Rails approach, what it is, and when it’s appropriate. This first video introduces the notion of Hexagonal Architecture, and talks about how it effects the relationship with the database – which ends up being a choice between the Active Record and Data Mapper patterns.
还深深埋在心底，要除去，怕是不能活命。
