Hello!
I'm working on a (more or less) flexible system with plugins should be
installed just like controllers; some basic information about them
(particulary, numerical id) must be kept in database.
Plugins should be handle some queries in /admin/service/$servicename
I'd like to put 'smart links' in plugin information table - i.e. if
something handles /admin/service/$servicename/control, link exists; if no -
instead of link text in different style is presented, telling that plugin
has not been installed.
construction like
[% SET path=stype.path %]
[% IF c.can('/admin/service/$path/control') %]
a href ...
[% ELSE %]
message here
[% END %]
is ugly; maybe someone points me to some nicer idea? I was thinking of some
function in Schema/Result/Servicetype.pm returning link or warning, but how
do I access the Catalyst object from it? Or I just have to pass it as
argument?
Alex.
The way I did this is using the namespace and action, since the
namespace is configurable.
http://search.cpan.org/~bobtfish/Catalyst-Runtime-5.80016/lib/Catalyst.pm#$c-get_action(_$action,_$namespace_)
If it returns undef, the action doesn't exist in the defined namespace.
