Easy to start
•Requirements are simple

•First steps are simple

Hard to maintain
•Edge cases start to appear

•New features are more
complicated

•Codebase become bigger
and harder to maintain
artist:ManuCornet
We use the wrong tools
• Callbacks in models and controllers and suppressing them

• Fat models

• Default scopes

• Custom actions in controllers

We have better tools
• Form Objects

• Service Objects

• Trailblazer

• DRY framework

– Your Coworker
“It makes no sense to create one
more class and one more file instead
of creating one private method”
Sandi Metz Rules
1. Classes can be no longer than one hundred lines of code.

2. Methods can be no longer than five lines of code.

3. Pass no more than four parameters into a method. Hash options are
parameters.

4. Controllers can instantiate only one object. Therefore view can only know
about one instance variable and views should only send messages to
that object.
Dima’s Rule
Don’t send parameters to private methods. Consider creating
a separate class.
POODR
Quick Recap
•Namespace models

•Namespace controllers and keep them small

•Namespace service classes and keep them
clean
