Help my config database - Webserver Nginx + mariaDB

What does your config and services file look like?

Your code is looking for a table users in a database named phalcon, which doesnt exist. Your connection should establish, since that would produce a different error message.

file config:

  use Phalcon\Config;
  use Phalcon\Logger;

  defined('BASE_PATH') || define('BASE_PATH', getenv('BASE_PATH') ?: realpath(dirname(__FILE__) . '/../..'));
  defined('APP_PATH') || define('APP_PATH', BASE_PATH . '/app');

The table name is 'ausers', I do not know where the phalcon is

Help my thanks!

Your service file seems OK, I think its simply a misconfiguration on your part.

First you must understand the error message: its complaining that you are querying against a table users in a database phalcon, and it cannot find it.

  return new Config([
      'database' => [
          'adapter'     => 'Mysql',
          'host'        => 'localhost',
          'username'    => 'username',
          'password'    => 'parssword',
          'dbname'      => 'dataname', // phalcon in your error log
          'charset'     => 'utf8',
      ],
  }

dbname should match with the database you've created within MariaDB. In case you're in doubt, you should install phpmyadmin on your box, so you can view your db structure in a nice GUI

It worked well!

in model:

      public function initialize()
      {
          $this->setSchema("phalcon"); /change my database name
      }

How can I acheive this with phalcon?

Im trying to acheive somelike how how Doctrine and Eloquent handle joins, Where the joined table is a child container (resultset in phalcons case) instead of multiple of the same user with diffrent joined servers. google street view maps
