Storable, reference help needed

[spstansbury]

I need to run a script and output some data to be used at a later time. Subsequent running of the script will use the stored data as baseline values to compare against new data.

I'm using Storable:

push @{$baseline}, \%base_record;
    
store( \$baseline, $baseline_records ) or die "Can't store %a in $base
+line_records!\n";

%base_record has a number of key/value pairs and gets pushed onto @{$baseline} every iteration of the loop. After the loop finishes, I store the AoH's. $baseline_records refers to the data file.

Data::Dumper shows:

$VAR1 = {
          'LICount' => 0,
          'LICountBase' => 0,
          'LIFloat' => 0,
          'LIFloatBase' => 0,
          'LIICount' => 0,
          'LIICountBase' => 0,
          'ProjectID' => 'STO1019001',
        };
$VAR2 = {
          'LICount' => 0,
          'LICountBase' => 0,
          'LIFloat' => 0,
          'LIFloatBase' => 0,
          'LIICount' => 0,
          'LIICountBase' => 0,
          'ProjectID' => 'STO1018001',
        };
$VAR3 = {
          'LICount' => 38,
          'LICountBase' => 38,
          'LIFloat' => 0,
          'LIFloatBase' => 0,
          'LIICount' => 11,
          'LIICountBase' => 11,
          'ProjectID' => 'STO1005001',
        };

When I retrieve the data, I'm getting:

my $arrayref = retrieve( $baseline_records );
print Dumper $arrayref;
$VAR1 = \[
            {
              'LICount' => 0,
              'LICountBase' => 0,
              'LIFloat' => 0,
              'LIFloatBase' => 0,
              'LIICount' => 0,
              'LIICountBase' => 0,
              'ProjectID' => 'STO1019001',
            },
            {
              'LICount' => 0,
              'LICountBase' => 0,
              'LIFloat' => 0,
              'LIFloatBase' => 0,
              'LIICount' => 0,
              'LIICountBase' => 0,
              'ProjectID' => 'STO1018001',
            },
            {
              'LICount' => 38,
              'LICountBase' => 38,
              'LIFloat' => 0,
              'LIFloatBase' => 0,
              'LIICount' => 11,
              'LIICountBase' => 11,
              'ProjectID' => 'STO1005001',
            }
          ];

I know that I'm not dealing with the references properly. The goal is, upon subsequent running of the script, when I loop through the project to return the values based on matching a "ProjectID"

Thanks in advance for any pointers.

Is there a reason you are storing a reference to a reference of an array?

Where you have store( \$baseline, $baseline_records ), maybe instead it should be store( $baseline, $baseline_records )?

This gives me identical output:

use Storable;
use Data::Dumper;

my $baseline_records = 'file.stor';

my $baseline = [
    {   'LICount'      => 0,
        'LICountBase'  => 0,
        'LIFloat'      => 0,
        'LIFloatBase'  => 0,
        'LIICount'     => 0,
        'LIICountBase' => 0,
        'ProjectID'    => 'STO1019001',
    },
    {   'LICount'      => 0,
        'LICountBase'  => 0,
        'LIFloat'      => 0,
        'LIFloatBase'  => 0,
        'LIICount'     => 0,
        'LIICountBase' => 0,
        'ProjectID'    => 'STO1018001',
    },
    {   'LICount'      => 38,
        'LICountBase'  => 38,
        'LIFloat'      => 0,
        'LIFloatBase'  => 0,
        'LIICount'     => 11,
        'LIICountBase' => 11,
        'ProjectID'    => 'STO1005001',
    }
];

store( $baseline, $baseline_records );
my $arrayref = retrieve($baseline_records);

print Dumper $baseline, $arrayref;

Thank you!
