Domain Driven Design Rails

Domain driven design for rails developers.

Domain driven design rails. All the objects have clear responsibilities and all interactions among them are explicit. The following article will describe an architecture of a rails application that is a combination of ideas from ddd and referenced articles as well as a few additional tools to monitor the quality of the code. An introduction to some of the concepts in domain driven design with a specific emphasis on repository pattern and how to apply them in ruby on rails. Then you have to consider additional requirements such as transactions integration with external systems event generation.

You know that domain driven design hexagonal architecture and the single responsibility principle are important but it s hard to know how to best apply them to rails applications. Also it is important to keep all logic applies to models in the domain layer because if you need to change some model behaviour you will change it only in one place. In this session you will learn a way out of the fat model skinny controller hell. Do rails apps and developers take on less complex problems and therefore don t require domain driven design.

They were useful to us and we are sure they are going to be useful for you and your complex apps. Let s take a look at what it is what kind of benefits it brings and how a typical rails application violates this. Rails is a web framework that supports high productivity through tightly coupling. One of the core concepts of domain driven design is the layered architecture.

You start with nicely designed groups of objects. This talk lays the groundwork of ddd and explores the tension between ddd and rails. In domain driven rails we describe 11 techniques that you can use separately and together in new and old rails apps to achieve better architecture. Domain driven design provides a framework and guidance for breaking up applications.

So main parts are. You will leave with a roadmap to guide your design based on. For a few years we ve been studying domain driven design and applying its techniques in our projects. The issue of why there is no domain driven design in rails came up on the herding code podcast episode with cory foy and will green.
