NAME

Dancer2::Plugin::ParamKeywords - Sugar for the params() keyword

VERSION

version v0.1.2

SYNOPSIS

use Dancer2;
use Dancer2::Plugin::ParamKeywords;

any '/:some_named_parameter' => sub {
    my $route_param = route_param('some_named_parameter');
    my $get_param   = query_param('some_named_parameter');
    my $post_param  = body_param('some_named_parameter');
};

DESCRIPTION

The default Dancer2::Core::Request params accessor munges parameters in the following precedence from highest to lowest: POST parameters, named route parameters, and GET parameters.

Consider the following route:

post '/people/:person_id' => sub {
    my $person_id = param('person_id');
    ...
    # Perform some operation using $person_id as a key
};

In the above example, if the browser/client sends a parameter person_id with a value of 2 in the POST body to route /people/1, $person_id will equal 2 while still matching the route /people/1.

This plugin provides keywords that wrap around params($source) for convenience to fetch parameter values from specific sources.

CONFIGURATION

The "munged_params" and "munged_param" keywords require you to configure an order of precedence by which to prefer parameter sources. Please see Dancer2::Core::Request params accessor for a list of valid sources.

# In config.yml
plugins:
  ParamKeywords:
    munge_precedence:
      - route
      - body
      - query

If you won't be using the munged_* keywords, you don't need to bother configuring this plugin.
