RoR Devise: Sign in with username OR email

Question

What\'s the best way to enable users to log in with their email address OR their username? I am using warden + devise for authentication. I think it probably won\'t be too h

Answer 1

I use a quick hack for this, to avoid changing any devise specific code and use it for my specific scenario (I particularly use it for an API where mobile apps can create users on the server).

I have added a before_filter to all the devise controllers where if username is being passed, I generate an email from the username ("#{params[:user][:username]}@mycustomdomain.com") and save the user. For all other calls as well, I generate the email based on same logic. My before_filter looks like this:

def generate_email_for_username
    return if(!params[:user][:email].blank? || params[:user][:username].blank?)
    params[:user][:email] = "#{params[:user][:username]}@mycustomdomain.com"
end

I am also saving username in the users table, so I know that users with email ending in @mycustomdomain.com were created using username.
