Rails - Devise, Email Case Insensitivity

I'm using Devise with login credentials: email/password - no usernames

I just noticed that the login process is case sensitive for emails. so if you register with [email protected], and then try to log in with [email protected] you get an error. Very confusing.

How can I make devise log people in with their email/password, and the email being case insensitive?

Devise addresses the issue here:

You can easily fix the issue like below. 

# config/initializers/devise.rb
Devise.setup do |config|
  config.case_insensitive_keys = [:email, :username]
end

I also had some solution which making work with email is case-insensitive for all Devise controllers (functionality):

class ApplicationController < ActionController::Base
...
...
  prepend_before_filter :email_to_downcase, :only => [:create, :update]
...
...
  private
...
...
  def email_to_downcase
    if params[:user] && params[:user][:email]
      params[:user][:email] = params[:user][:email].downcase
    end
  end
...
...
end

I know it is not the best solution: it involves another controllers of another models and executes code which is not necessary for them. But it was just makeshift and it works (at least for me ;) ).

Kevin and Andres, thanks for your answers. It is really good solutions and useful. I wanted to vote them up, but I haven't enough reputation yet. So, I just tell 'thanks' to you. ;)

Lets wait for Devise 1.2

I added this to my User model to store it case-sensitive but make it case-insensitive during sign in:

def self.find_for_database_authentication(conditions = {})
  self.where("LOWER(email) = LOWER(?)", conditions[:email]).first || super
end

It works on Heroku.

By the way, this is just a temporary fix as the issue has been resolved and this will be the default behavior on Devise 1.2. See this pull request for details.

One option is to override the find method used by devise. Something like:

# User.rb
before_save do
  self.email.downcase! if self.email
end

def self.find_for_authentication(conditions) 
  conditions[:email].downcase! 
  super(conditions) 
end
