[web2py] web2py iteration output

[blackshirt]

i have a little problem with web2py.
i'm doing simple writing application with web2py. the code look like
this


for controller  :

import apt_pkg
def important():
    apt_pkg.init()
    cache = apt_pkg.Cache()
    for pkg in cache.packages:
       if pkg.essential:
           return dict(t=pkg)

and for related view :

{{extend 'layout.html'}}
<ul>
<li>{{=t.name}}</li>{{pass}}
</ul>

if we run this script on python shell, the output should like this

base-files
 sysvinit-utils
 util-linux
 diffutils
 perl-base
 bash
 login
 e2fsprogs
 dash
 coreutils
 bsdutils
 base-passwd
 dpkg
 findutils
 debianutils
 sed
 tar
 ncurses-base
 grep
 mount
 gzip
 ncurses-bin
 hostname
 sysvinit


but when we run through web2py, the output just first entry from list
of essential packages above. it looks like this

. base-files

what wrong with my code.. i'm still pretty newbie on python and web2py
