I see this warning in my log

…/app/models/user.rb:179: warning: Object#id will be deprecated; use  
Object#object\_id

I am using in my user model ‘self.id’ to the mysql record id of the  
user which gives me correctly 25

the self.object\_id is not the sql record id…

… whta’s the right writing ??

thanks

kad

Usually this error occurs when you call id on something that isn’t an  
ActiveRecord::Base object. Check all possible calls of #id at line 179  
of user.rb. Then insert “puts object.class.name” debug statement for  
each object on which you call id to verify the actual class.
