Provide output if related. Provide coredump if any. Use https://github.com/phalcon/cphalcon/wiki/Generating-a-backtrace as reference

<?php

        $model->exec_time = 0.1212;

        $saved = $model->update();
    }
}

DB Scheme

CREATE TABLE `logs_tasks` (
  `id` int(10) unsigned NOT NULL AUTO_INCREMENT,  
  `exec_time` decimal(9,3) DEFAULT NULL,
  `pid` int(10) unsigned NOT NULL,
  PRIMARY KEY (`id`),
  KEY `pid` (`pid`)
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;

When update model get error

@Jurigag Could you please take a look

[Jurigag]

Yea, can you provide your table schema?

[mzf]

@Jurigag added in start post

[409H]

What happens if you do $model->exec_time = floatval(0.1212);

[mzf]

@409H same error on $this->update() line

[Jurigag]

Can't reproduce.

ini_set('display_errors', 1);

$di = new FactoryDefault();
$di->set(
    'db',

        $adapter = new \Phalcon\Db\Adapter\Pdo\Mysql(
            [
                'host'     => 'localhost',

require "LogsTasks.php";

$model = new LogsTasks;
$model->pid = 1212;
$model->save();

$model->exec_time = 0.1212;

$saved = $model->update();

var_dump($saved); // true

Checked on php 7.1.1 but i doubt that on 7.0 there will be difference

[mzf]

What am I doing wrong?

[mzf]

I test this code on Phalcon 3.0.4 - work fine.
On 3.1.0 same error

[Jurigag]

I don't know, you sure you posted full code of your model? Just with this code you posted i don't have error.

[mzf]

@Jurigag i ran you code and get error

Fatal error: Uncaught Error: Class 'FactoryDefault' not found

What version you use?

[Jurigag]

Oh i forgot use statements:

use Phalcon\Di\FactoryDefault;
use Phalcon\Mvc\Model;

[mzf]

Your example work fine on Phalcon 3.1.1. Thanks!
I'll figure out what I've done

[Jurigag]

Maybe you need to clear metadata? I don't know really.

[mzf]

Try this example please.

<?php
ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);

use Phalcon\Di\FactoryDefault;
use Phalcon\Mvc\Model;

class ModelDynamicUpdate extends \Phalcon\Mvc\User\Plugin
{

    /**
     * @var boolean
     */
    protected $dynamicUpdate;

    /**
     * @param boolean $dynamicUpdate
     */
    public function __construct($dynamicUpdate = true)
    {
        $this->dynamicUpdate = $dynamicUpdate;
    }

    /**
     * @param \Phalcon\Events\Event               $event
     * @param \Phalcon\Mvc\Model\ManagerInterface $modelsManager
     * @param \Phalcon\Mvc\ModelInterface         $model
     */
    public function afterInitialize(\Phalcon\Events\Event $event, \Phalcon\Mvc\Model\ManagerInterface $modelsManager, \Phalcon\Mvc\ModelInterface $model)
    {
        $modelsManager->useDynamicUpdate($model, $this->dynamicUpdate);
    }
}

$di = new FactoryDefault();
$di->set(
    'db', function () {
    $adapter = new \Phalcon\Db\Adapter\Pdo\Mysql(
        [
        'host' => 'localhost',
        'username' => 'root',
        'password' => '',
        'dbname' => 'phalcon_test',
        'options' => [
            PDO::ATTR_EMULATE_PREPARES => false,
            PDO::ATTR_STRINGIFY_FETCHES => false,
            PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES utf8',
        ],
        'charset' => 'utf8',
        ]
    );

    return $adapter;
}
);

$di->set('modelsManager', function () {

    $eventsManager = new \Phalcon\Events\Manager;
    $modelsManager = new Model\Manager;
    $eventsManager->attach("modelsManager", new ModelDynamicUpdate(true));
    $modelsManager->setEventsManager($eventsManager);

    return $modelsManager;
});



require "LogsTasks.php";

$model = new LogsTasks;
$model->pid = 1212;
$model->save();

$model->exec_time = 0.1212;

$saved = $model->update();

var_dump($saved); // true

?>

[Jurigag]

Yea, now i see, let me fix it.

[Jurigag]

Created PR.

[sergeyklay]

Fixed in the 3.1.x branch.
