You just restated what i had initially written. The "problem" is something to do with how rails connects newly initialized objects that are in memory but not yet in the database. We have built two objects like this u = User.new im = InstitutionMembership.new :user => u At that point the u (User) object doesn't know anything about the im object. Saving the u object does not trigger an autosave on the association, and the create callback creates a new membership. That's somewhat expected. The odd issues appear after - u = User.new im = InstitutionMembership.new :user => u u.save im.save 'im' is aware of the user object, however it is not able to validate against it. When it attempts to validate, the user_id==NULL. At the very next log entry though, it saves itself with the correct user_id. So somewhere between the validate callbacks, and the create and commit callbacks, the 'im' object refreshed the user object and retrieved the user_id. Also the new_record? flag on 'im' is still set, so a new row is created. One of the better solutions was actually to do: u = User.new im = u.institution_memberships.build This is able to properly connect the objects in memory, and the process works smoothly. The association is autosaved on u.save -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
