Module Login::UsernameFinder
In: lib/login/username_finder.rb

An extremely simple module that allows me to put the logic for determining the username is one place.

Methods

username_field  

Public Instance methods

username_field()

Will get the currently configured username field. If not defined then email, then username, then user_name will be attempted. If none of those fields exist then nil is returned which will probably cause an error in the application.
