Sorting by an attribute on a associated table
So, I have a User has_many :profiles. The most recently dated profile is
considered the current one. I need to sort these users by name, but the
name attribute is a member of the associated table.
Is there any easy way to do this other than with some ugly find_by_sql?
Maybe a more general question - is there a common solution to sorting in
Ruby?

I''m trying to figure out how to best allow a user to click a
link_to_remote (or something like it) that will make the clicked thing
disappear and replace it with a "Saving..." or "Please wait..." image
until the server round-trip is complete. Once complete, it needs to
replace the HTML in that span or div with text from the server.

Redirect whole page from AJAX action that updates a div
Hi,
I am calling an action via AJAX to update a div. The action needs to
redirect the page in under certain circumstances. However, if I just use
"redirect_to" in the action then of course what happens is that the page
I want to redirect to replaces only the div, not the entire page, and I
get messy nested layouts.
Is there a way around this? Can I redirect the entire document from

Ajax Request Caching by Timestamp?
Hi everyone, first post here in the forum. I''m usually in #rubyonrails
on freenode.
I''ve been thinking about the various types of caching, and I was
wondering if its possible to have the server selectively send back data,
instead sending nothing ''0'' if user has the newest data.
My example is a presence monitor, and it seems like the logic is:

I''m looking at how to do ad-hoc database queries from RoR models - more
specifically I have built an app which tracks issues which uses its own
