I am trying to figure out a correct way to do master detail type pages with Rails. All the online demos I could find that had two tables in one post were habtm and they are not close enough to be useful. Say we wanted a page for creating/editing an invoice which allowed us to edit the invoice header and the invoice_lines on the same page. In the rhtml file how should the invoice_lines input fields be generated. Do I have to do something like the following (which doesn''t work as is) and them iterate through and save each invoice_line individualy? <p>Line 1 Descrption<%= text_field ''invoice'', ''lines[0].description'' %></p> <p>Line 2 Descrption<%= text_field ''invoice'', ''lines[1].description'' %></p> How should the post save the lines, is there a way for the invoice save to save the invoice_lines at the the same time in the same way the habtm relationship does? I can think of a number of ways of achieving the above but none of them are tidy. I must be missing something. Most of the solutions I have come up with require the invoice header to be commited first on a previous page or action. Any help appreciated. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
