Loading fixtures, does not update sequence (Postgres)

[tino415]

When I load fixtures, sequence number of tables are not updated or updated to wrong values,
I'm using this fix:

<?php

namespace tests\codeception\fixtures;

use yii\test\ActiveFixture;
class DocumentTypeFixture extends ActiveFixture {

    public $modelClass = 'app\models\DocumentType';

    public function load() {
        parent::load();

        if($this->db->drivername === 'pgsql') {
            $this->db->createCommand("SELECT pg_catalog.setval(".
                "pg_get_serial_sequence('document_type', 'id'),".
                "(SELECT MAX(id)+1 FROM document_type)".
            ")")->execute();
        }
    }
}

Error message:

1) tests\codeception\unit\crawlers\SuperMusicDocumentCrawlerTest::testCrawling
yii\db\IntegrityException: SQLSTATE[23505]: 
Unique violation: 7 ERROR:  duplicate key value violates unique constraint "document_type_pkey"
DETAIL:  Key (id)=(3) already exists.
The SQL being executed was: INSERT INTO "document_type" ("name") VALUES ('taby')

Fixture data:

<?php

return [
    'type' => [
        'id' => 1,
        'name' => 'type',
    ],
    'type' => [
        'id' => 2,
        'name' => 'type2',
    ],
    'type' => [
        'id' => 3,
        'name' => 'type333',
    ],
];

[dynasource]

why would this occur with id=3 and not already with id=2?

INSERT INTO "document_type" ("name") VALUES ('taby')

this does also not match with the fixture data you supplied. Hard to verify.

Please reopen with correct information

It is long time closed project, I'm unable to verify.

I have the same problem.

Fixture for table push_notification:

<?php

return [
    'push1' => [
        'id' => 1,
        'customer_id' => 1,
        'type_id' => 1,
        'data' => '{"likedById":2}',
        'status' => 'new',
        'errors' => 0,
        'updated_at' => '2017-06-23 00:00:04',
    ],
    'push2' => [
        'id' => 2,
        'customer_id' => 2,
        'type_id' => 2,
        'data' => '{"likedById":1}',
        'status' => 'processing',
        'errors' => 0,
        'updated_at' => '2017-06-23 00:00:05',
    ],
    'push3' => [
        'id' => 3,
        'customer_id' => 1,
        'type_id' => 1,
        'data' => '{"likedById":3}',
        'status' => 'done',
        'errors' => 0,
        'updated_at' => '2017-06-23 00:00:02',
    ],
    'push4' => [
        'id' => 4,
        'customer_id' => 5,
        'type_id' => 1,
        'data' => '{"likedById":4}',
        'status' => 'not found',
        'errors' => 1,
        'updated_at' => '2017-06-23 00:00:07',
    ],
    'push5' => [
        'id' => 5,
        'customer_id' => 4,
        'type_id' => 2,
        'data' => '{"likedById":2}',
        'status' => 'failed',
        'errors' => 1,
        'updated_at' => '2017-06-23 00:00:06',
    ],
    'push6' => [
        'id' => 6,
        'customer_id' => 4,
        'type_id' => 2,
        'data' => '{"likedById":1}',
        'status' => 'new',
        'errors' => 0,
        'updated_at' => '2017-06-23 00:00:01',
    ],
    'push7' => [
        'id' => 7,
        'customer_id' => 2,
        'type_id' => 1,
        'data' => '{"likedById":5}',
        'status' => 'done',
        'errors' => 0,
        'updated_at' => '2017-06-23 00:00:00',
    ],
    'push8' => [
        'id' => 8,
        'customer_id' => 1,
        'type_id' => 2,
        'data' => '{"likedById":4}',
        'status' => 'failed',
        'errors' => 20,
        'updated_at' => '2017-06-23 00:00:03',
    ],
    'push9' => [
        'id' => 9,
        'customer_id' => 2,
        'type_id' => 2,
        'data' => '{"likedById":1}',
        'status' => 'processing',
        'errors' => 15,
        'updated_at' => '2017-06-23 00:00:09',
    ],
];

Then try to do

INSERT INTO "push_notification" ("customer_id", "type_id", "data", "status") VALUES (1, 1, '[]', 'new') RETURNING "id";

The error will be:

ERROR:  duplicate key value violates unique constraint "push_notification_pkey"
DETAIL:  Key (id)=(1) already exists.

After sending the query 10 times the error disappears (when id becames 10).

I’m fixing it this way:

protected function _before()
{
    $this->tester->haveFixtures([
        'notifications' => PushNotificationFixture::className(),
    ]);
    // Postgres fix
    Yii::$app->db
        ->createCommand("SELECT setval('push_notification_id_seq', max(id)) FROM push_notification;")
        ->execute();
}

But it’s a kludge.

What about something like this? Related method.

Rough but working implementation.

    public function load()
    {
        $this->data = [];
        $table = $this->getTableSchema();
        foreach ($this->getData() as $alias => $row) {
            $primaryKeys = $this->db->schema->insert($table->fullName, $row);
            $this->data[$alias] = array_merge($row, $primaryKeys);
        }
        if ($table->sequenceName !== null && count($primaryKeys) > 0) {
            //recalculate sequence based on last inserted id
            $primaryKey = key($primaryKeys);
            $lastId = (new Query())->select('max('. $primaryKey .')')->from($table->fullName)->scalar();
            $this->db->createCommand()->resetSequence($table->fullName, $lastId)->execute();
        }
    }
