pabcas - Thanks for responding to my question. I really appreciate
the help. Changing my partial to use "UserSession.new" seemed to
work. The "home" page was able to render properly.
I checked the user_sessions_controller.rb file and I have this method
defined.
def new
@user_session = UserSession.new
end
Did you mean the home_controller.rb file?
