问题 I have an existing Rails 4 application which uses Devise and Omniauth . I'm trying to modifying my existing app to develop an API (I mean I will have my web app as it is and also I want an API for mobile app) but I'm having a hard luck.

问题 I'm wanting to use UUIDs in an app I'm building and am running into a bit of a problem. Due to UUIDs (v4) not being sortable because they're randomly generated, I'm trying to override ActiveRecord::Base#first, but Rails isn't too pleased with that. It yells at me saying ArgumentError: You tried to define a scope named "first" on the model "Item", but Active Record already defined a class method with the same name. Do I have to use a different method if I want to sort and have it sort

I'd like to do something like: class BarsController < ApplicationController def test authorize bar, @foo, :show? # Throws ArgumentError ... end end But the Pundit
