Question

I am making a login using AuthLogic, but I would like ’email’ to be optional. It seems however that authlogic out of the box makes this validated for. Anyone know a workaround?

Answer 1

from the authlogic example rails application:

1. Set up your model

Make sure you have a model that you
will be authenticating with. Since we
are using the User model it should
look something like:

class User < ActiveRecord::Base
  acts_as_authentic do |c|
    c.my_config_option = my_value # for available options see documentation in: Authlogic::ActsAsAuthentic
  end # block optional  
end

One thing to note here is that this tries
to take care of all the authentication
grunt work, including validating your
login, email, password, and token
fields. You can easily disable this
with configuration. Ex:
c.validate_email_field = false. See
the Authlogic::ActsAsAuthentic sub
modules in the documentation for more
details.

Key part to note:

You can easily disable this with configuration. Ex:
c.validate_email_field = false.

Hope that helps.
