[Catalyst] Re: OT: Better TT pager?

Hi, there, Oliver and everyone:)

 Thanks for your posting:)
 Referring to
http://www.mail-archive.com/catalyst@lists.scsys.co.uk/msg05232.html, I
adopted the code given into my template and it looks really good but the
hyperlink doesn't have any value. I suppose it's because [%
c.req.uri_with(...) %] is not defined.

1)why is the Catalyst request variable being used instead of the
Catalyst object?
2)how can we get the Catalyst request working properly (ie to be defined)?


thank you :)

I might as well join in with this :) Here's what we use at work:

[% IF pager %]
    <ul class="paginator">
        <li class="counter">Page [% pager.current_page %] of [%
pager.last_page %]</li>
        <li><a href="[% c.req.uri_with( page => pager.first_page )
%]">&laquo;</a></li>
        [% IF pager.previous_page %]
            <li><a href="[% c.req.uri_with( page =>
pager.previous_page ) %]">&lt;</a></li>
        [% END %]

        [% start = (pager.current_page - 3) > 0 ? (pager.current_page -
3) : 1;
         FOREACH page IN [ start .. pager.last_page ] %]
            [% LAST IF loop.count > 6 %]
            <li[% IF pager.current_page == page; ' class="current"'; END %]>
                <a href="[% c.req.uri_with( page => page ) %]">[% page
%]</a>
            </li>
        [% END %]

        [% IF pager.next_page %]
            <li><a href="[% c.req.uri_with( page => pager.next_page )
%]">&gt;</a></li>
        [% END %]
        <li><a href="[% c.req.uri_with( page => pager.last_page )
%]">&raquo;</a></li>
    </ul>
[% END %]

Though my colleague rightly suggested we subclass Data::Page and
perform the sliding window in there. This shows first page, previous
page, the current page surrounded by near-by pages. Seems to do the
job so far!
