I am working with PhalconPHP and so far I have had little problems.

The framework is very good.

However, I've run into a problem that I haven't been able to sort out. It's probably a very simple thing but I've been running in circles, and couldn't find any reference to this problem.

The problem is I cannot update a model object if I also update a related entity.

For example, let's suppose I have a couple of model classes.

Contact:

class Contact extends \Phalcon\Mvc\Model
{
    public function initialize()
    {
        $this->belongsTo('email_id', 'Email', 'id', ['alias' => 'Email']);
    }
}

And Email:

class Email extends \Phalcon\Mvc\Model
{
    public function initialize()
    {
        $this->hasMany('id', 'Contact', 'email_id', ['alias' => 'Contacts']);
    }
}

When I try to create a new Contact and Email the following works:

$contact = new Contact();
// ... assign other fields here (i.e. name)
$email = new Email();
// ... assign other email fields here (i.e. address)
$contact->setEmail($email); // or $contact->email = $email;
$contact->save();
// record created

However, when I try to update a Contact and change the Email relation, the information is just not updated:

// Only update other fields
$contact->name = 'Some other name';
$contact->save();    // This works

// Update the related object
$contact->name = 'A new name';
$contact->setEmail($anotherValidEmail);
$contact->save();    // This doesn't work! Not even the name field is updated

I have tried using update() instead of save().

I have tried using $contact->email = $newEmailObject as well, but I get the same results.

Have anyone ran into this problem? What am I doing wrong?

I'm using Mac OS X, PhalconPHP 1.2.3

I've also tested it on Windows 8, with PhalconPHP 1.1.0

Any help is appreciated.

updated

I have printed the results of $contact->getMessages() after save(), but I get no results. It's as if save() was successful, however, no SQL statement is executed.

LAST UPDATE: Problem replicated and Workaround found!

We have been able to replicate the problem. We are doing this:

$contact = Contact::findFirst(123);
if ($contact->email->emailaddress != $newaddress) {
    $email = new Email();
    $email->emailaddress = $newaddress;

    $contact->email = $email;
    $contact->save();
}

This DOES NOT WORK! Once we compare the emailaddress field from the email related object, to the string for the new address saving does not work.

However, if we modify the code a little bit and do this:

  $contact = Contact::findFirst(123);
  if ($contact->email->emailaddress != $newaddress) {
    $email = new Email();
    $email->emailaddress = $newaddress;

    // Load the record (again!)
    $contact = Contact::findFirst(123);
    $contact->email = $email;
    $contact->save();
  }

This actually works.

I guess that loading the related object affects the ability to update that particular field, and finding the contact object again, flushes the related object.

So, we have a workaround that I hope will help other people facing the same problem.

使用时$contact->setEmail($anotherValidEmail);，Contact模型Contact中必须有set和get方法。例如：

Class Contact
{

  public $email;

  public function setEmail($email)
  {
  }
  public function getEmail()
  {
    return $this->email
  }
}

官方文档中有答案，您应该尝试一下（添加标志ACTION_CASCADE）：

<?php

namespace Store\Models;

use Phalcon\Mvc\Model,
    Phalcon\Mvc\Model\Relation;

class Robots extends Model
{

    public $id;

    public $name;

    public function initialize()
    {
        $this->hasMany('id', 'Store\\Models\Parts', 'robots_id', array(
            'foreignKey' => array(
                'action' => Relation::ACTION_CASCADE
            )
        ));
    }

}

http://docs.phalconphp.com/en/latest/reference/models.html#cascade-restrict-actions

如果主记录（机器人）被删除，上面的代码设置为删除所有引用的记录（部分） 。

您还可以使用 beforeDelete 或 afterDelete 函数并添加所需的任何代码：

Actually, your model should look like as below

class Contact extends \Phalcon\Mvc\Model
{

  public $id;
  public $name;
  public $email;

  public function initialize()
  {
     $this->belongsTo('email_id', 'Email', 'id', ['alias' => 'Email']);
  }

  public function columnMap()
  {
      return array(
        'id' => 'id', 
        'name' => 'name', 
        'email' => 'email'
      );
  }

}

然后，

$联系人 = 新联系人（）；

$success = $contact->save($this->request->getPost(), array('name', 'email'));
