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

Use real code. Inventing something doesn''t actually help anyone figure

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".

and A.commission += 0.5

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.
