Your understanding is absolutely right. My initial gut was indeed to try hidden inputs. But it does not work:
App B calls appA/foos/new?size=4&weight=2 App A foo/new method is called and the form is pre-populated with size and weight. The problem is, the URL is still appA/foos/new?size=4&weight=2. When the form is submitted, I think what happens is Rails tries to append the form parameters to the existing URL. Since that URL already contains parameters it does something like: appA/foos/new?size=4&weight=2?size=4&weight=2&price=10 etc and the second set of parameters after the second "?" is ignored by the browser. At least that's my understanding (I could be wrong). I guess it would work if I could remove the first set of params. But it looks like I will need to do a redirect_to. I was thinking there might be a cleaner way. Sorry it is a bit convoluted... Thanks!
