I’m curious if anyone has any examples they would like to share on how  
to  
implement tiered subscriptions. I’ve seen a few methods myself, but I’d  
like  
to know how others are doing it.

I’ve seen

User has\_many :subscriptions  
User has\_one :current\_subscription

I’ve also seen the subscription info stored as a hash. I don’t like that  
as  
much, but it is quick and dirty.

What I am really interested in is how you check for permissions?  
Controller  
level? Model level?

I’d appreciate any insight you have to offer. Thanks in advance!
