What does "no_default" field property mean?

Hi Jaume Albaigès,

This property is used by DBManager class to return default value for a field/column if any.

If this property is set to true, no default value would be returned for the field definition but if it is set to false, function would look out for any 'default' property being set and then return the value appropriately.

To know more, you can check out getDefaultFromDefinition function inside include/DBManager.php file.

protected function getDefaultFromDefinition($fieldDef)
{
    $default = '';
    if (!empty($fieldDef['no_default'])) {
        // nothing to do
    } elseif ($this->getFieldType($fieldDef) == 'bool') {
        if (isset($fieldDef['default'])) {
            $value = (int) isTruthy($fieldDef['default']);
        } else {
            $value = 0;
        }
        $default = " DEFAULT " . $value;
    } elseif (isset($fieldDef['default'])) {
        $default = " DEFAULT " . $this->massageValue($fieldDef['default'], $fieldDef);
    }
    return $default;
}

Regards.

Thank you very much for your quick and good answer, hats. Now I understand the usage of the property although I don't understand its needing. Wouldn't it be enough by processing default property?
