Question

环境：
CakePHP 3
Postgres的

我尝试迁移以添加新字段，然后在Postgres数据库中更新该字段的某些数据。该实体似乎表明它已更新，但当我查看数据库时，它不会被保存。

代码

<?php
use Cake\Cache\Cache;
use Cake\ORM\TableRegistry;
use Migrations\AbstractMigration;

class AddDisplayRouteNumberToAgencies extends AbstractMigration
{
    /**
     * Up Method.
     */
    public function up()
    {
        $table = $this->table('agencies');
        $table->addColumn('display_route_number', 'boolean', [
            'default' => true,
            'null' => false,
        ]);
        $table->update();

        // Try to clear the Model cache
        Cache::clear(null, '_cake_model_');

        $patchData = [
            'display_route_number' => false
        ];

        $agencies = TableRegistry::get('Agencies');

        $agency = $agencies->get(25);
        // And save it back to the DB
        $agencies->patchEntity($agency, $patchData);
debug($agency);
        // Added after comment from ndm
        $agencies->save($agency);
    }

    /**
     * Down method
     */
    public function down()
    {
        $table = $this->table('agencies');
        $table->removeColumn('display_route_number');
        $table->update();

        // Clear the CakePHP Model cache
        Cache::clear(null, '_cake_model_');
    }
}

debug()

的结果

object(App\Model\Entity\Agency) {
    'id' => (int) 25,
    'full_name' => 'Agency',
    'legacy_agency_slug' => null,
    'created' => object(Cake\I18n\Time) {

        'time' => '2015-11-19T10:58:51+0000',
        'timezone' => 'UTC',
        'fixedNowTime' => false

    },
    'modified' => object(Cake\I18n\Time) {

        'time' => '2015-11-19T10:58:51+0000',
        'timezone' => 'UTC',
        'fixedNowTime' => false

    },
    'display_route_number' => false,
    '[new]' => false,
    '[accessible]' => [
        '*' => true
    ],
    '[dirty]' => [
        'display_route_number' => true
    ],
    '[original]' => [],
    '[virtual]' => [],
    '[errors]' => [],
    '[repository]' => 'Agencies'
}

Postgres查询和结果

SELECT id, display_route_number
FROM agencies
WHERE id = 25;

 id | display_route_number 
----+----------------------
 25 | t
(1 row)

其他尝试

我还尝试使用save()而不是patchEntities()，它返回了相同的结果，但[dirty]为空。

    $agencies = TableRegistry::get('Agencies');
    $agency = $agencies->get(25);
    // Items to update
    $agency->display_route_number = false;
    // And save it back to the DB
    $agencies->save($agency);

Answer 1

感谢@ndm为我解决这个问题。我最终不得不更新表架构。我相信这是因为Migration表部分更新了SQL，但没有更新Schema。

这是最终的代码：

    // Clear the CakePHP Model cache
    Cache::clear(null, '_cake_model_');

    $table = $this->table('agencies');
    $table->addColumn('display_route_number', 'boolean', [
        'default' => true,
        'null' => false,
    ]);
    $table->update();

    $agencies = TableRegistry::get('Agencies');

    // REQUIRED!! Add the field to the Table schema
    $agencies->schema()->addColumn('display_route_number', [
        'type' => 'boolean',
        'default' => true,
        'null' => false
    ]);

    $agency = $agencies->find()
        ->where(['short_name' => 'bart'])
        ->first();
    // Items to update
    $agency->display_route_number = false;
    // And save it back to the DB
    $agencies->save($agency);

CakePHP 3：迁移不保存更新数据
