Rails MVC: How to deal with fat models

My presentation on the last DRUG (Wroclaw Ruby User Group, D stands for Dolnoslaskie) about Rails fat models.
I covered some of the techniques we use in our projects:

  • current_user is never nil
  • a class for each user type - User, Guest, Admin, SuperAdmin, Partner
  • remove "if" statements from views
  • minimize the number of "if" statements in controllers and models
  • modules to extract common behavior from models
  • one controller action calls only one model method
  • in controllers everything goes through current_user
  • using custom exceptions for Model - Controller communication

It wasn't recorded.

If anyone is interested, I'm always happy to present the topics over Skype or any other way.
