I recently had to develop a small application for a client. The goal was to add a feature to grown Java web application.
As the software was maintained for several years there are users with old an new MySql passwords in the system.
To authenticate the user I have chosen authenticate_or_request_with_http_basic
As I just needed handful of actions all of them go in one controller:
class MyController < ApplicationController before_filter :authenticate def index # [ ... ] end protected def authenticate authenticate_or_request_with_http_basic do |id, password| @user = User.find_by_name(id) login_ok = @user.authenticate(password) login_ok end end end
To check if the user can be authenticated:
class User < ActiveRecord::Base def authenticate(password) user = User.find_by_sql(["select * from user where user_pass=password('%s') \ OR user_pass=old_password('%s')",password,password]) (user.length > 0)?true:false end end
Its a very simple approach.
What do you think?
