dear Ruby friends

It’s fun to talk about …

Microservices, bounded contexts, DDD, DCI, Hexagonal, Clean

Architecture, UncleBob, events, CQRS, streams, microapps

but…

Then we go back to our controllers

so called, real life

Can you safely improve it? !

step by step? !

quickly?

it’s difficult

but possible !

even without tests

safe techniques include:

• inline controller filters

• move model callbacks into controller

• render views explicitly without @ivars

• move action to a new class (service object)

• …

I need more examples of ugly controllers and

models

Send them to me, please :) !
