I''ve run into a bit of a problem with saving 2 related, but different, object records at once: When a user registers, they specify the name of the organization they belong to. Upon a successful registration, a new user record and a new organization record is created. However, I can''t figure out how to only create the organization if the user record is validated. Specifically, the organization name is not an attribute of the user, so I cannot retrieve the organization name using user.organzation_name in the after_create callback in the user model. Any ideas on how to create one record, and then create another object that is related to that record? Now that sounded confusing... - Derek -- Derek Haynes HighGroove Studios - http://www.highgroove.com Keeping it Simple. 404.593.4879
I do this sort of thing in the app I''m working on now, assuming I
understood you correctly. (And I probably did. Heh)
Caveat: I''m a relative Rails newbie, so don''t do an IPO based
on this
e-mail.
def destroy_spacetime
unless params[:blackhole] then
redirect_to :action => ''somewhere''
return
end
@black_hole = session[:event_horizon] || Anomaly.new
@black_hole.attributes = params[:blackhole]
@universe = Universe.new
@universe.attributes = params[:universe]
if @black_hole.valid? && @universe.valid? then
@black_hole.save
@universe.save
else
redirect_to :action => ''where_we_came_from''
return
end
session[:event_horizon] = @black_hole
end
