Php 为Phalcon模型创建一个表

我是Phalcon PHP框架的初学者

我已经创建了一个模型。像这样：

class User extends Phalcon\Mvc\Model
{

    /**
     * @Primary
     * @Identity
     * @Column(type="integer", nullable=false)
     */
    public $id;

    /**
     * @Column(type="string", nullable=false)
     */
    public $username;

    /**
     * @Column(type="string", nullable=false)
     */
    public $email;

    /**
     * @Column(type="string", nullable=false)
     */
    public $first_name;

    /**
     * @Column(type="string", nullable=false)
     */
    public $last_name;

    /**
     * @Column(type="string", nullable=false)
     */
    public $password;

    public function getSource()
    {
        return "users";
    }
} 

现在我想做一些ORM操作

User::count(array('email = :email:', 'email' => $email)) == 0;

我得到了这个错误：

SQLSTATE[42S02]：找不到基表或视图：1146表“dbname.users”不存在

---

该表实际上不存在，因此我应该如何创建它？手动通过SQL查询或使用Phalcon框架中的特定工具？

在简要回顾了Phalcon文档之后，我想您正在寻找类似的东西=>

用法示例：

<?php
use \Phalcon\Db\Column as Column;

$connection->createTable(
    "robots",
    null,
    array(
       "columns" => array(
            new Column("id",
                array(
                    "type"          => Column::TYPE_INTEGER,
                    "size"          => 10,
                    "notNull"       => true,
                    "autoIncrement" => true,
                )
            ),
            new Column("name",
                array(
                    "type"    => Column::TYPE_VARCHAR,
                    "size"    => 70,
                    "notNull" => true,
                )
            ),
            new Column("year",
                array(
                    "type"    => Column::TYPE_INTEGER,
                    "size"    => 11,
                    "notNull" => true,
                )
            )
        )
    )
);

非常感谢您！要自动创建表，最好在哪里找到此代码？您只需运行此代码一次，准备一个仅在初始设置时调用的文件
<?php

use Phalcon\Db\Column as Column;
use Phalcon\Db\Index as Index;
use Phalcon\Db\Reference as Reference;

class ProductsMigration_100 extends \Phalcon\Mvc\Model\Migration
{

    public function up()
    {
        $this->morphTable(
            "products",
            array(
                "columns" => array(
                    new Column(

                            "size"          => 10,
