Where to put constraint classes in Rails project
lib/ would be the appropriate place. If you want to make it cleaner, put it in lib/constraint/authenticated.rb and define your constraints like so
module Constraint class Authenticated def matches?(request) # stuff end endendand in your routes.rb
constraints Constraint::Authenticated.new do match 'account' => 'account#index'end
This is strange that the guide says nothing about that path, but lib/constraints is even listed in the API (ActionDispatch::Routing::Mapper::Scoping):
You are able to move this logic out into a class if it is too complex for routes. This class must have a
matches?method defined on it which either returns true if the user should be given access to that route, or false if the user should not.class Iphone def self.matches?(request) request.env["HTTP_USER_AGENT"] =~ /iPhone/ endendAn expected place for this code would be lib/constraints.
