REST::Application::Routes(3pm) User Contributed Perl Documentation REST::Application::Routes(3pm)NAME
REST::Application::Routes - An implementation of Ruby on Rails type routes.
SYNOPSIS
package MyApp;
use base 'REST::Application::Routes';
my $obj = REST::Application::Routes->new();
$obj->loadResource(
'/data/workspaces/:ws/pages/:page', => &do_thing,
# ... other routes here ...
);
sub do_thing {
my %vars = @_;
print $vars{ws} . " " . $vars{page} . "
";
}
# Now, in some other place. Maybe a CGI file or an Apache handler, do:
use MyApp;
MyApp->new->run("/data/workspaces/cows/pages/good"); # prints "cows good"
DESCRIPTION
Ruby on Rails has this concept of routes. Routes are URI path info templates which are tied to specific code (i.e. Controllers and Actions
in Rails). That is routes consist of key value pairs, called the route map, where the key is the path info template and the value is a
code reference.
A template is of the form: "/foo/:variable/bar" where variables are always prefaced with a colon. When a given path is passed to "run()"
the code reference which the template maps to will be passed a hash where the keys are the variable names (sans colon) and the values are
what was specified in place of the variables.
The route map is ordered, so the most specific matching template is used and so you should order your templates from least generic to most
generic.
See REST::Application for details. The only difference between this module and that one is that this one uses URI templates as keys in the
"resourceHooks" rather than regexes.
METHODS
These are methods which REST::Application::Routes has but its superclass does not.
getTemplateVars()
Returns a hash whose keys are the ":symbols" from the URI template and whose values are what where matched to be there. It is assumed that
this method is called either from within or after "loadResource()" is called. Otherwise you're likely to get an empty hash back.
getLastMatchTemplate()
This is an alias for "getLastMatchPattern()", since this class is about templates rather than regexes.
