Override automatic update of updated_on column

i know that title sounds confusing, but here is the deal:

the two columns that we are concerned with for this question are the
“updated_on” column and the “views” column. the views column increases
everytime a user visits a certain page. like this:

@object.update_attributes(:views => @object.views + 1)

the problem is that when a user visits the page, it AUTOMATICALLY
updates the “update_on” column with the current time. i don’t want this
to happen. how can i rewrite this so it DOES NOT update the “update_on”
column and only the “views” column?
