Module: Reins::Routes::UrlHelpers

Included in:
Controller, View
Defined in:
lib/reins/routes/url_helpers.rb

Overview

Single shared module mixed into Reins::Controller and Reins::View. Methods are added by the DSL at route declaration time, removed on ‘reset!` (called by `Application#route` so each fresh app has a clean helper namespace).

One process is expected to host one Reins::Application; running two in the same process will overwrite each other’s helpers.
