Improve channel, user and api_key models with basic scopes, correct references and protect attributes. Simplify channels & user controllers and models, moving code to the models. Remove catch-all route and ensure all actions are specified, fixing url paths. Change clone to dup in feed_controller as using clone seems to affect the cloned object (problem only in ruby 1.9.3?) 2012-02-10 00:42:16 +01:00			`module KeyUtilities`

Fix returning an API Key that was size + 1. 0..size iterates through size + 1 elements. So asking for an API that was 16 was actually returning a string of 17 characters. This broke trying to shove it into a varchar(16) in PostgreSQL. 2013-04-20 15:51:21 +02:00			`end`
