I'm trying to figured this out, but I still can't do it.
I have a rails 3 app, I'm working with invoices and payments. In the
form for payments I have a collection_select where I display all the
invoices number (extracted from a postgres database), and what I'm
trying to do is when i select an invoice autopopulate others
text_fields (provider, address, etc.) without reloading the page, in
the same form.
I know I should use ajax, js, jquery, but I'm a beginner in these
languages, so i don't know how or where to start
hope you can help me... thanks
