www/p5-Catalyst-Plugin-Params-Nested 0.05_1 FreeBSD

Ruby on Rails has a nice feature to create nested parameters that help with the organization of data in a form - parameters can be an arbitrarily deep nested structure.

The way this structure is denoted is that when you construct a form the field names have a special syntax which is parsed.

This plugin supports two syntaxes:

dot notation

    <input name="foo.bar.gorch" />

subscript notation

    <input name="foo\[bar\]\[gorch\]" />

When reading query parameters from $c->req you can now access all the items starting with "foo" as one entity using $c->req->param('foo');. Each subitem, denoted by either the dot or the square brackets, will be returned as a further deeper hashref.
