Hi Dave, All,
I found a solution - It was easy -
wrote a new function that takes a parameter, called it in the view and it
redirects to the required page.
query = (db.fotoz.album_name == "%s" % request.args(0))
and have this
<p> <a href="{{=URL(r=request, c='default', f='view_album',
args=[allalbums[i].album_name])}}" class="btn">View Album</a></p>
in view.
That sends the argument to this function and displays the album. The only
issue is with spaces in album names that dont work.
Cheers, Rahul
