Hello friends,  
I am getting this warning _warning: Object#id will be deprecated; use  
Object#object\_id_ on the following line of code

def to\_s()  
output = "\nDO Class: " + self.class.to\_s() + “\n”  
output += " id: " + id().to\_s() + “\n”  
output += " position: " + position.to\_s() + “\n”  
output += " photo\_id: " + photo.id().to\_s() + “\n”  
\*output += " slideshow\_id: " + slideshow.id().to\_s() + “\n”

- output += “end”  
return output  
end

I dont know what does it mean. I will appreciate if any one can help me  
in  
this.  
Thank you in advance  
karry

I would think that somehow slideshow does not hold an active record  
object when it gets to that line… so it call the deprecated Object.id  
instead.
