I thnk in some places you use request.vars.id and in other places you
use request.args(0) and that is the confusion. Try this:
def edit_journal():
opskrif = T('Editing journal record no. %d') %
int(request.vars.id)
vorm = crud.update(db.akb_journal, request.args(0),
deletable = False,
next = 'articles/[id]') # << shortcut
return dict(vorm=vorm, opskrif=opskrif)
def show_journal():
opskrif = H1(T('Journal record no. %d') % int(request.args(0)))
vorm = crud.read(db.akb_journal, request.args(0))
link =
A('Edit',_href=URL('default','edit_journal',args=request.args(0)))
return dict(vorm=vorm, opskrif = opskrif, link=link)
