Showing changes to a FieldInfo (field) object

The following example illustrates how to use the HCL Compass API to get information about field values that have changed for a given record.

Perl

# entity->GetFieldsUpdatedThisAction returns all fields that have changed...

$oSess = $entity->GetSession();

$username = $oSess->GetUserLoginName();

$action = $entity->GetActionName();

$state = $entity->GetFieldValue("State")->GetValue();

my ($sec, $min, $hour, $mday, $mon, $year, $wday, $yday, $time) = 
localtime();

$now = sprintf("%2.2d/%2.2d/%4d %2.2d:%2.2d:%2.2d", $mon + 1,$mday, $year + 
1900, $hour, $min, $sec);

$body = "Fields Changed by $username, $action->$state, $now\n\n";

$fields = $entity->GetFieldsUpdatedThisAction();

for ($i = 0; $i < $fields->Count(); $i++) {

   $field = $fields->Item($i);

   $fname = $field->GetName();

   $newVal = &GetStrValue($oSess, $field);

   $oldVal = &GetStrValue($oSess, $entity->GetFieldOriginalValue($fname));

   unless($fname eq "Notes_Log"){

      unless($newVal eq $oldVal){

         $body .= "* $fname: $val\n";

      }

   }

}

$body .= "\n";

$fieldlog = $entity->GetFieldValue("FieldLog")->GetValue();

$newLog = $body . $fieldlog;

$entity->SetFieldValue("FieldLog", $newLog);



# Start of Global Script GetStrValue

# This is used to handle different types of fields...

sub GetStrValue {

   my ($session, $field) = @_;

   $val = "";

   $type = $field->GetType();

   if ($type lt 6) { #string, int, date, reference

      $val = $field->GetValue();

   } elsif ($type eq 6) { # Reference_list

      $list = $field->GetValueAsList();

      foreach $item (@$list) {

         $val .= "\n\t$item";

      }

   } elsif ($type eq 9) { #State

      $val = $field->GetValue();

   }

   return $val;

}
