In a model are there any methods that are called before providing  
access to the model?

I’m exploring ways to enforce privileges in my app. Wondering if I can  
define some sort of “before” method in the model to prevent read  
access to the model unless certain conditions are true.

Thanks.

Evan

Go to [http://api.rubyonrails.org/](http://api.rubyonrails.org/) read about ActiveRecord::Callbacks
