Hi all,

I’m running into a brick wall trying to figure out my problem here. I  
have a model that has a boolean property called “paid”. I’d like to  
add the following to my model:

def after\_save  
self.amount == self.splits.sum(:amount) ? self.update\_attribute  
(:paid, true) : self.update\_attribute(:paid, false)  
end

The problem is, when I do this I get an error that my stack level is  
too deep. If I throw this in with one of the model’s validators it  
works just fine, but that’s not the right way to do this…

I don’t see how I’m recursing here, so any help would be appreciated!

Thanks!

update\_attribute saves the updated record, so after\_save will be called  
again, hence the recursion.

You should update by sql in after\_save.
