an error while running a migration

Did you change your developer tools version or anything? I remember i once had problems with it after I changed developer tools versions. It also generates a directory .phalcon . Did you include that aswell?

cd phalcon_dev_tools git checkout 3.3.* git pull

try phalcon migration run alain =)

Thanks. So I pulled and switched to branch 3.3.x. This did not seem to help though. :(

Okay, here is what happened to the best of my knowledge. I worked on this site on a local server (ubuntu 16.04 + apache on a local network). Everything was working, migrations including. then I had a break for a couple of weeks, When I came back to it Idecided to change db structure a bit, removed old migrations 1.0.0-5 (had quite a few of them by the time), removed the file in /.phalcon that stores migration versions, made changes to the database manually and ran "phalcon migration generate". to generate 1.0.0 again. Then I updated vendors/libs via composer. I have dev-tools installed that way too, and when I made a new 1.0.1 manually with the $_connection in the code and attempted to run the migration this is when I noticed the problem.

Here is the full print out

PHP Fatal error: Uncaught Error: Access to undeclared static property: VersionsMigration_101::$_connection in /www/sapi/app/migrations/1.0.1/versions.php:12

Stack trace:

and here is simplified migration code with the self::$_connection line #12 that caused the error

<?php

use Phalcon\Mvc\Model\Migration;

class VersionsMigration_101 extends Migration {

private $table_name = 'versions';

public function up() {

self::$_connection->query('TRUNCATE TABLE ' . $this->table_name);

} ...

}

maybe phalcon.so not included in cli php ? execute in console :

php -m | grep phalcon 

Finded ? P.S how insert tag for formatting code here ?

php -m | grep phalcon

Finded ?

Yes, found

phalcon
