[web2py] get vars from view to my def

[cyber]

Hi there!

I need a hint of how to get variable value from view to my function in
controller.

My code in controller:
***************************************************************************************************
* def work():
*    row=db.executesql('SELECT * FROM autos WHERE autos.id=20')
*    return dict(row=row)
***************************************************************************************************

My code in the view (new.html):
***************************************************************************************************
* {{for r in records:}}
* {{=A(r.id,_href=URL('work', vars={'i':r.id}))}}
***************************************************************************************************

As you see I can select one row from db by id but I want work function
to get current id instead "autos.id=20"
I have no ideas of how to use variable from view in my controllers
def.

So, any proposals!?! Please...
