How to run before\_safe only if a database field contains a certain  
value?

I tried:

before\_save { |guest| guest.password = md5\_pass(guest.password) ,  
:if =\> :enabled? }

def enabled?  
self.deleted == 1  
end

No success!

That shouldn’t work. I think you are getting before\_save confused with  
built-in validations. Try it like this:

before\_save { |guest| guest.password = md5\_pass(guest.password) if  
guest.enabled? }

Ok, that’s it! Thanx.
