Overview

About Authem

Authem is an email-based authentication library for ruby web apps.

Authem requires Ruby 1.9.3 or newer

Please see the Authem website for up-to-date documentation: http://authem.org

Run bundle update authem and make sure you are on the 2.0.x release.
Remove references to the old Authem::Config object.
Create the new sessions table with rails g authem:session.
Replace include Authem::ControllerSupport with authem_for :user.
Rename signed_in? to user_signed_in? OR alias_method :signed_in?, :user_signed_in? in your controller.
Rename column User#reset_password_token to User#password_reset_token OR alias_attribute :password_reset_token, :reset_password_token in your User model.
Replace calls to user#reset_password_token! with user#password_reset_token. Tokens are now generated automatically and the bang method is deprecated.
Rename sign_out to sign_out_user OR alias_method :sign_out, :sign_out_user
If you were passing a remember flag as the second argument to sign_in, you need to provide an options hash instead. For example, sign_in(user, params[:remember]) would become sign_in(user, remember: params[:remember]).
Blank email addresses will now produce the proper "can't be blank" validation message". Update your tests accordingly.
Email addresses are no longer automatically downcased when calling find_by_email on your model. You will need to downcase the value manually if you wish to retain this behavior.
Specify what to do when authem denies access to a user by adding something like this to your ApplicationController.

def deny_user_access
  redirect_to :sign_in
end
