440: When we stray from Rails defaults
The Bike Shed
Navigating Callbacks and Rails Best Practices
In the Rails ecosystem, a distinction is made between elements above and below the web-facing layers, with a preference for utilizing available tools and frameworks above this line to avoid manual pain points. Experimentation with alternative libraries, such as Dry RB, indicates an openness to diverging from traditional Rails approaches. There is a growing awareness in the community regarding the pitfalls of using callbacks in Active Record, as they can complicate code by creating tight coupling between business logic and data persistence. This concern stems from the realization that callbacks, often introduced early in development, may not align with their intended purpose, leading to undesirable dependencies that complicate future maintenance. Best practices suggest that separating business logic from callbacks can promote cleaner architecture, preventing issues associated with tightly-coupled components. Overall, insight favors weighing the necessity of callbacks against potential alternatives to enhance code clarity and maintainability.
