How to Rails

Disclaimer: complex apps only

What is wrong with Rails?

• Magic (implicit vs explicit)
• Coupling (ActiveRecord)

Ingredients

• Repository pattern or CQRS
• Use case classes
• Rails framework

Sad but true

Repository pattern is hard

Follow Arkency blog post for a starting point

but keep in mind that this is not a perfect solution

Why Repository?

• Decouple DB stuff from Business model
• You can mock repository in tests
