Re: MongoDB replacing an array

This is just a general idea. You'll probably need to adjust the validation options in order for it to work.

#!/usr/bin/perl

use strict;
use warnings;
use MongoDB;
use DateTime;

my $today = DateTime->now;
my $stamp = DateTime->now->set(
    'timestamp' => $today->day,
);

my $database = '/tmp/collection';
$database->update(
    {'host' => '127.0.0.1'},
    {'set' => {"timestamp" => 'new'}},
    {'multiple' => 1, 'safe' => 1}
);

New quoted without an array '@'? In my original example '@new' is any array. Neil Watson watson-wilson.ca	[reply]

I can't find any documentation to indicate that there is any sort of validation that happens during an insert or update of a generic column.	[reply]

I believe this is correct: $col->update( { "host" => $host }, { '$set' => { "timestamp" => \@new } }, { 'multiple' => 1, 'safe' => 1 } ) \|\| die "$!"; It should be a array ref instead.	[reply]
