Sadly, I cannot understand what it is you're trying to do, or what help you are asking for.

Which function?

also, i had create a model to the commission: [code] id - user_id - contact_id - ammount - date [/code] the user model is like that: [code] id - user_name - ..... - contact - .... 1 - foo - ...... - Null - 2 - bar - ...... - foo [/code]

Use real code. Inventing something doesn't actually help anyone figure out what is going on.

thank you for reply: what i want to do is when a user C make a purchase, his godparent ( user B ) win some money and also the godparent of B ( user A). in the users table i come to add a column named "commission". so when B make purchase, B.commission += 1 and A.commission += 0.5 there's a way to do this please. what code you want!?

Start by working right through a good rails tutorial such as railstutorial.org. That will show you the basics of Rails. Then you will probably be able to answer your own question.
