module Athena::Routing::Generator::Interface #

Allows generating a URL for a given ART::Route.

routes = ART::RouteCollection.new
routes.add "blog_show", ART::Route.new "/blog/{slug}"

generator = ART::Generator::URLGenerator.new context
generator.generate "blog_show", slug: "bar-baz", source: "Crystal" # => "/blog/bar-baz?source=Crystal"

Parameter Default Values#

By default parameters with a default value the same as the provided parameter will be excluded from the generated URL. For example:

routes = ART::RouteCollection.new
routes.add "articles", ART::Route.new "/articles/{page}", {"page" => "1"}

ART.compile routes

generator = ART::Generator::URLGenerator.new ART::RequestContext.new
generator.generate "articles"          # => "/articles"
generator.generate "articles", page: 1 # => "/articles"
generator.generate "articles", page: 2 # => "/articles/2"

If you want to always include a parameter, add a ! before the ART::Route#path, for example:

routes.add "users", ART::Route.new "/users/{!page}", {"page" => "1"}

generator.generate "users"          # => "/users/1"
generator.generate "users", page: 1 # => "/users/1"
generator.generate "users", page: 2 # => "/users/2"

URL Types#

Athena::Routing supports various ways to generate the URL, via the reference_type parameter. See ART::Generator::ReferenceType for description/examples of the possible types.
