Maypole::Plugin::LinkTools - convenient link construction

SYNOPSIS

use Maypole::Application qw( LinkTools );

#...

print $request->maybe_link_view( $thing );

print $request->maybe_many_link_views( @things );

print $request->link( table      => $table,
                      action     => $action,        # called 'command' in the original link template
                      additional => $additional,    # optional - generally an object ID
                      label      => $label,
                      );
                      
print $request->make_path( table      => $table,
                           action     => $action,        # called 'command' in the original link template
                           additional => $additional,    # optional - generally an object ID
                           );

                           

DESCRIPTION

Provides convenient replacements for the link and maybe_link_view templates, and a new maybe_many_link_views method.

Centralises all path manipulation, so that a new URI scheme can be implemented site-wide by overriding just two methods (Maypole::parse_path() and Maypole::Plugin::LinkTools::make_path()).

For ease of use with the Template Toolkit, make_path, link and link_view will also accept a hashref of arguments. For example:

print $request->make_path({ table      => $table,
                            action     => $action,
                            additional => $additional,
                         });

METHODS

make_path( %args or \%args )

This is the counterpart to Maypole::parse_path. It generates a path to use in links, form actions etc. To implement your own path scheme, just override this method and parse_path.

%args = ( table      => $table,
          action     => $action,        # called 'command' in the original link template
          additional => $additional,    # optional - generally an object ID
          );

id can be used as an alternative key to additional.

link( %args or \%args )

Returns a link, calling make_path to generate the path.

%args = ( table      => $table,
          action     => $action,        # called 'command' in the original link template
          additional => $additional,    # optional - generally an object ID
          label      => $label,
          );

The table can be omitted and defaults to that of the request's model. id can be used as an alternative key to additional.

link_view( $thing or %args or \%args )

Build a link to the view action of the given item. If passed a Maypole request object, builds a link to its view action.

print $request->link_view( $maypole_request );

print $request->link_view( table      => $table,
                           label      => $label,
                           additional => $id,
                           );
                           

maybe_link_view( $thing )

Returns stringified $thing unless it isa Maypole::Model::Base object, in which case a link to the view template for the object is returned.

maybe_many_link_views

Runs multiple items through maybe_link_view, returning a list.
