Hey all -  
I have an odd ball situation where I want to check the parent  
ActiveRecord object to see if the child rows have been loaded already  
or not. I’m sure the answer is probably staring me right in the  
face… but it’s Monday and my brain isn’t firing all of it’s pistons  
yet!

Thanks

Nevermind… I just thought I’d try the obvious…and of course Ruby  
came through…

parent\_object.child\_rows.loaded?

This returns a boolean one way or the other… hope my morning  
fogginess helps someone else out!
