[Catalyst] sending a variable to more than one tt2 template

[Ian Sillitoe]

yup, I'm using reusable TT2 widgets via [% PROCESS widget.tt2 %] to render
given objects (e.g. row of a given table) so I can call them from several
other TT2 pages (and on their own in AJAX calls).

root/src/foo/list.tt2
[% FOREACH foo =3D list_of_foos %]
  [% PROCESS foo/brief_summary.tt2
            entry =3D foo
  %]
[% END %]

root/src/foo/brief_summary.tt2
<h1>[% entry.title %]</h1>
<p>[% entry.content %]</p>

If you want to display the same widgets on the page for "bar" (which also
have "foos")

root/src/bar/list.tt2
[% FOREACH foo =3D bar.get_foos %]
  [% PROCESS foo/brief_summary.tt2
            entry =3D foo
  %]
[% END %]

FWIW I can then serve these widgets on their own in simple AJAX calls by
changing the wrapper applied in root/lib/site/wrapper (e.g. based on CGI
param "?format=3DAJAX"). Sending HTML snippets via AJAX is less efficient t=
han
sending JSON and client-side rendering with javascript (Jemplate), but when
the components are small and simple, I've found this useful.
