Hi,
I''ve been banging my head against this problem for a while, trying to
figure out where it''s occurring. I have a (I believe) relatively
simple application, not entirely unlike a typical shopping cart, which
is generating errors upon *some* page loads.
The errors are along the lines of "ActiveRecord::RecordNotFound
(Couldn''t find Estimate with ID=3)". The odd part about this is
that
refreshing the page (which attempts to again locate the estimate with
id=3) succeeds - at least in all experiences, although I imagine it
could fail twice in a row. So, the data is there an exists, but
there''s a failure somewhere in the retrieval process.
I have two machines I am testing this on, one is a macbook pro,
running Leopard, the other a p4 running FreeBSD 6.2. Below is
software information for each machine:
Mac:
ruby 1.8.6 (2007-06-07 patchlevel 36) [universal-darwin9.0]
Rails 1.2.5
Mongrel Web Server 1.1.1
postgres (0.7.1) - ruby gem for accessing postgresql (have also tried
postgres-pr, with same result)
psql (PostgreSQL) 8.2.5
FreeBSD box:
ruby 1.8.6 (2007-03-13 patchlevel 0) [i386-freebsd6]
Rails 1.2.5
Mongrel Web Server 1.1.1
postgres-pr (0.4.0)
psql (PostgreSQL) 8.2.5
Both setups experience the same issue.
Below are two renderings of the same page, the second of which
generated an error about not finding the exact same estimate I had
just seen a moment before (and could view again upon reloading the
page).
