php - Phalcon 迁移系统中的 auto_increment

Question

出于某种原因，迁移系统在使用 auto_increment 主键时表现不佳。我在监督什么吗？ (我使用的是 phalcon 2.0.1)

我有以下自动生成的迁移:

class LanguagesMigration_100 extends Migration
{

public function up()
{
    $this->morphTable(
        'languages',
        array(
        'columns' => array(
            new Column(
                'id',
                array(
                    'type' => Column::TYPE_INTEGER,
                    'notNull' => true,
                    'autoIncrement' => true,
                    'size' => 11,
                    'first' => true
                )
            ),
            new Column(
                'ccode',
                array(
                    'type' => Column::TYPE_VARCHAR,
                    'notNull' => true,
                    'size' => 6,
                    'after' => 'id'
                )
            ),
            new Column(
                'active',
                array(
                    'type' => Column::TYPE_INTEGER,
                    'notNull' => true,
                    'size' => 1,
                    'after' => 'ccode'
                )
            )
        ),
        'indexes' => array(
            new Index('PRIMARY', array('id')),
            new Index('UNIQ_A0D153794EE11504', array('ccode'))
        ),
        'options' => array(
            'TABLE_TYPE' => 'BASE TABLE',
            'AUTO_INCREMENT' => '9',
            'ENGINE' => 'InnoDB',
            'TABLE_COLLATION' => 'utf8_unicode_ci'
        )
    )
    );
}
}

但是当我运行该迁移时，生成的 sql 会:

如您所见，id 字段已修改，不包括 auto_increment。

我正在回答我自己的问题，因为它似乎是 Phalcon 迁移系统中的一个错误。

正如@axalix 指出的那样，迁移是在以前存在的表上完成的。 (我赞成你的回答，因为它帮助我找到了解决方案)。

这是原始表格:

CREATE TABLE `languages` (
  `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `ccode` varchar(6) COLLATE utf8_unicode_ci NOT NULL,
  PRIMARY KEY (`id`),
  UNIQUE KEY `ccode` (`ccode`),
  KEY `ccode_2` (`ccode`)
) ENGINE=InnoDB AUTO_INCREMENT=9 DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci

这是修改后的表(由 doctrine orm:schema-tool 修改)

CREATE TABLE `languages` (
  `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `ccode` varchar(6) COLLATE utf8_unicode_ci NOT NULL,
  `active` tinyint(1) NOT NULL,
  PRIMARY KEY (`id`),
  UNIQUE KEY `UNIQ_A0D153794EE11504` (`ccode`)
) ENGINE=InnoDB AUTO_INCREMENT=9 DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci

原来是我忘记了Doctrine实体中的“unsigned”选项，所以当表格被改变时，表格看起来像

CREATE TABLE `languages` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `ccode` varchar(6) COLLATE utf8_unicode_ci NOT NULL,
  `active` tinyint(1) NOT NULL,
  PRIMARY KEY (`id`),
  UNIQUE KEY `UNIQ_A0D153794EE11504` (`ccode`)
) ENGINE=InnoDB AUTO_INCREMENT=9 DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci

出于某种原因，在没有未签名选项的情况下运行 phalcon 迁移使其忘记了 auto_increment。

我将尝试单独重现它以将错误报告给 Phalcon 人员。
