flarnie / Validate Email in RoR
Created August 17, 2013 14:14
The right way to validate uniqueness case insensitive of email in Ruby on Rails.
##Check uniqueness of email-----------------------------------------------
#in migration
add_index :users, :email, :unique => true
#but that doesn't cover case insensitive
#in the model take email to lowercase before save
class User..
attr_accessible :email
#this gives you custom message for the error
