Basic vanilla Rails... Your parent table (resort_basic?) should have an ID column. All your child tables (like resort_contact?) should include a field named resort_basic_id of type integer. class resort_basic has_many :resort_contacts etc, etc end class resort_contact belongs_to :resort_basic end You can: -> use a hidden field on the resort_contact form to store the resort_basic_id, setting this value in the resort_contact controller''s new method if the vlaue is known, then retrieve that from the params in the create method -> or the resort_contact form may include a droplist field where you choose the resort_basic ID as part of creating the resort contact -> or some other more advanced methods, but the nature of your question leads me to believe that you should stick to the basics for now. As for links: http://api.rubyonrails.org/ or http://www.google.com There are tons of examples out there that don''t have to be repeated here. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

If you''re trying to do this with a single model, I assume that you''ll have to: 1. construct that model so it contains equivalents for all the fields from all the tables. 2. Pass this model from view to view, editing some fields, and keeping the rest as hidden fields on each form. Like form1 shows fields 1 and 2, hides fields 3 through 10. Form 2 shows fields 3 and 4, hides 1, 2, 5 through 10, etc. 3. the controller has to know which form submitted so it knows what to do next... go to the next form, or try to save the data. A variable stored in a hidden field should suffice for that, @current_step or something like that. 4. When you finally submit from view 5 and go to save, extract the fields for the parent table and save that record. Re-read that record to get its id, and put that in the parent id field for each of the sets of fields you have to save to your child tables. And wrap it all in a transaction so you can rollback if the third or fourth model fails validation. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
