Small macro to define unique random token generator for ActiveRecord.
How to Use
## Basic class ApplicationController < ActionController::Base include MiniLogin # MiniLogin#login! creates current_user, otherwise raises MiniLogin::Unauthorized def login_required login! current_user end # If not logged in, redirect to login form rescue_from MiniLogin::Unauthorized do redirect_to new_session_path end end class SessionController def create user = User.find_by_email(params[:email]) if user && user.authenticate(params[:password]) login! user # MiniLogin as found and authenticated user else render :new # Authenticate again end end end
gem 'mini_login', :git => 'git://github.com/fujimura/mini_login.git'
Rails 3.1.x and maybe Rails 3.0.x
letmein is small and beautiful piece.
But with Rails 3.1.x, which came with SecurePassword, login solution could be more minimalistic.
