虚拟字段与Cakephp 3 [英] Virtual fields with Cakephp 3

问题描述

我需要在我的用户实体中有一个虚拟属性。我遵循 CakePHP图书。

I need to have a virtual property in my user entity. I followed the CakePHP book.

UserEntity.php

UserEntity.php

namespace App\Model\Entity;

use Cake\ORM\Entity;

class User extends Entity {

    protected $_virtual = ['full_name'];

    protected function _getFullName() {
        return $this->_properties['firstname'] . ' ' . $this->_properties['lastname'];
    }
}

/ p>

In a controller

$users = TableRegistry::get('Users');
$user = $users->get(29);
$firstname = $user->firstname; // $firstname: "John"
$lastname = $user->lastname; // $lastname: "Doe"
$value = $user->full_name; // $value: null

我完全按照这本书，我只得到一个 null value。

I followed exactly the book and I only get a null value.

推荐答案

根据@ndm，问题是由于文件命名错误。我命名了用户实体类 UserEntity.php 。 CakePHP名称约定说：

According to @ndm, the problem was due to a bad file naming. I named the user entity class UserEntity.php. The CakePHP name conventions says that:

实体类OptionValue将在名为OptionValue.php的文件中找到。

The Entity class OptionValue would be found in a file named OptionValue.php.

谢谢。
