Description
Při čisté instalaci je problém v tom, že simple-form se snaží načíst z cache položky pro svoje nabídky, ale tato cache se sama nevytvoří v případě, že neexistuje.

Oki, diky za nahlaseni.
Je to divne, protoze jsem to programoval tak, at se zepta, jestli klic existuje a pokud ne, at se jednoduse zavola prislusny dotaz.
Maku, prosim, dodej mi vice udaju, protoze kdyz smazu /var/mentat/cache a najedu na stranku alerts, tak se cache soubory vytvori..
root@mentat:/usr/local/mentat# ls -al /var/mentat/cache/

Overit, ze se z mongo nejaka data vrati..
Osetrit situaci, kdy se Model pripadne snazi ulozit "nic" do cache.
Pravdepodobne je chyba zde (na porade se domluvime vice, jak to pripadne osetrit):
lib/Mentat/Storage/Mongo/Aggregator.pm
my $error = $self->{CACHE}->cache($key, $data);
# Report the error
if ($error)
{
Log::Loger->error(__PACKAGE__, "Cache error: $error");
die "$error\n";
}
- Status changed from In Progress to Resolved
Opraveno, sice ne jeste finalne, ale problemove misto ano. Vcetne osetreni databaze:
my $selector_data = [];
eval {
$selector_data = $self->{STORAGE}->aggregate($pipeline);
};
if ($@) {
my $message = "Unable call aggregate function of MongoDB: $@";
Log::Loger->error(__PACKAGE__, $message);
}
my @data = ();
foreach (@$selector_data)
{
push (@data, $_->{_id});
}
# return back
$result->{$key} = \@data;
# save cache
my $error = $self->{CACHE}->cache($key, \@data, $rewrite);
if ($error)
{
Log::Loger->error(__PACKAGE__, "Cache error: $error");
die "$error\n";
}
