grp.exists()

I don't think that you can gain much by replacing grp.find with something simpler. If you need to do grp.find very often then you should cache the data somehow, maybe do a db query to get all objects at once.

I have a project with hotel and I am creating and updating ga's based on json so I am searching the most efficient way for checking such thing. Thanks for reply
