merb-action-args
A plugin for the Merb framework that provides support for arguments to actions that come in from the query.
{{[ class Foo < Merb::Controller
def bar(baz) bar end
end ]}}
Hitting "/foo/bar?baz=bat" will call foo("bat").
Hitting "/foo/bar" will raise a BadRequest (Status 400) error.
{{[ class Foo < Merb::Controller
def bar(baz, bat = "hola") "#{baz} #{bat}" end
end ]}}
Hitting "/foo/bar?baz=bat" will call foo("bat", "hola")
Hitting "/foo/bar?baz=bat&bat=whaa" will call foo("bat", "whaa")
Hitting "/foo/bar" will still raise a BadRequest.
{{[ class Foo < Merb::Controller
def bar(one, two = "dos", three = "tres") "#{one} #{two} #{three}" end
end ]}}
The interesting thing here is that hitting "/foo/bar?one=uno&three=three" will call foo("uno", "dos", "three"). In other words, the defaults can be in any order, and merb-action-args will figure out where to fill in the holes.
