Symfony 2 Doctrine 2 EntityManager配置

Question

i'm trying to get my Doctrine CommandLine Tool working in Symfony 2 project on Windows 7 and I keep getting the same error message in console:

Fatal error: Call to protected Doctrine\ORM\EntityManager::__construct()
from invalid context in C:\wamp\www\firstSymfonyApp\cli-config.php on line 9

Call Stack:
0.0010     239440   1. {main}() C:\wamp\www\firstSymfonyApp\vendor\doctrine\orm\bin\doctrine.php:0
0.0090     621376   2. require('C:\wamp\www\firstSymfonyApp\cli-config.php') C:\wamp\www\firstSymfonyApp\vendor\doctrine\orm\bin\doctrine.php:48

Code of my cli-config.php file:

<?php
use Doctrine\ORM\Tools\Console\ConsoleRunner;
require_once 'app/bootstrap.php.cache';
$em = new \Doctrine\ORM\EntityManager();
return ConsoleRunner::createHelperSet($em);

Until today, I was only using doctrine on Linux where the installation was much more simple, please help me work this out.

Answer 1

Error message is very clear. EntityManager::__construct is protected method therefore you can't use it outside of the class.

Check out EntityManager::create.

Check this link for more information about how to start with Doctrine 2.

This is probably the snippet which should be important to you right now:

<?php
// bootstrap.php
require_once "vendor/autoload.php";

use Doctrine\ORM\Tools\Setup;
use Doctrine\ORM\EntityManager;

$paths = array("/path/to/entity-files");
$isDevMode = false;

// the connection configuration
$dbParams = array(
    'driver'   => 'pdo_mysql',
    'user'     => 'root',
    'password' => '',
    'dbname'   => 'foo',
);

$config = Setup::createAnnotationMetadataConfiguration($paths, $isDevMode);
$entityManager = EntityManager::create($dbParams, $config);
