Update: After mulling this over for a few hours, I have concluded that
I'm asking two distinct questions:
Q1: If I have a page that contains a partial that contains a form that
invokes an action in MyController, how do I return the results to the
original page?
A1a: I could (somehow) arrange to have the form emit the
controller/method combo that would get me back to the original page,
and, after MyController has done its thing, call
render('controller/method') to get back to it.
A1b: I could use redirect_to env["HTTP_REFERRER"], but unlike
render(...), that's a separate transaction, so I'll need to store my
temporary Store objects somewhere. See Q2.
Q2: Where can I squirrel away unsaved Store records across transactions
(e.g. if I use redirect_to as per A1b above)?
A2a: Use the session hash. (This feels really wrong)
A2b: Stop fighting Rails and save the Store records. Create a
StoreLocator model, make it responsible for creating Store records and
pruning the ones we don't use. Or something like that.
Any better suggestions?
