UPDATE: Stranger and stranger. I do NOT get this error running in the console. I do NOT get this error running the test suite. I ONLY get this error under 'rails server'. I tracked the Rails source to where the AssociationTypeMismatch is raised in association_proxy.rb:
def raise_on_type_mismatch(record) unless record.is_a?(@reflection.klass) || record.is_a?(@reflection.class_name.constantize) message = "#{@reflection.class_name}(##{@reflection.klass.object_id}) expected, got #{record.class}(##{record.class.object_id})" raise ActiveRecord::AssociationTypeMismatch, message end end and inserted a Rails.logger.debug() statement. When I'm running in the test suite, I see: >>> class=NOAA, record.is_a?(WeatherStation) => true, record.is_a?(WeatherStation) => true When I'm running in under the server, the same run prints: >>> class=NOAA, record.is_a?(WeatherStation) => false, record.is_a?(WeatherStation) => false Is there ANYTHING about the server environment (in development mode) that would account for is_a? behaving differently??? -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
