module Ibrain
# Configuration point for User model implementation.
#
# `Ibrain::UserClassHandle` allows you to configure your own implementation of a
# User class or use an extension like `ibrain-auth`.
#
# @note Placeholder for name of Ibrain.user_class to ensure later evaluation at
# runtime.
#
# Unfortunately, it is possible for classes to get loaded before
# Ibrain.user_class has been set in the initializer. As a result, they end up
# with class_name: "" in their association definitions. For obvious reasons,
# that doesn't work.
#
# For now, Rails does not call to_s on the instance passed in until runtime.
# So this little hack provides a wrapper around Ibrain.user_class so that we
# can basically lazy-evaluate it. Yay! Problem solved forever.
class UserClassHandle
# @return [String] the name of the user class as a string.
# @raise [RuntimeError] if Ibrain.user_class is nil
def to_s
fail "'Ibrain.user_class' has not been set yet." unless Ibrain.user_class
"::#{Ibrain.user_class}"
