440: When we stray from Rails defaults

When does it make sense to step away from Rails conventions? What are the limits of convention over configuration? While Rails conventions provide a solid foundation, there are times when customization is necessary to meet specific project needs. In this episode, Joël and Stephanie dive into the tradeoffs of breaking away from Rails defaults. They explore the limits of convention over configuration and share their experiences with customizing beyond the typical Rails setup. Joël offers insights from a recent project where the client opted for all dry-rb objects, and they unpack the benefits and potential challenges of this approach. Stephanie talks about why people tend to shy away from certain Ruby features and her lessons regarding leveraging callbacks for code development. Explore different testing frameworks, the situations when following Ruby defaults is better, the benefits of the ActiveModel ecosystem, and more! Whether you are a Rails purist or looking to bend the rules, this episode will help you understand the pros and cons of stepping outside the Ruby on Rails box. Don’t miss it!
