如何在CodeIgniter中安装Doctrine 3 [英] How to install Doctrine in CodeIgniter 3
问题描述
The official guide is not complete, and others are for CI2.
所以我给你一个我自己检查的教程正在工作。
So i give you a tutorial i myself checked is working.
我知道，鼓励用户回答自己的问题。
推荐答案
安装原则
可以使用<一个href =http://www.getcomposer.org/ =nofollow>作曲者。
在composer.json文件中定义以下要求：
Doctrine can be installed with Composer. Define the following requirement in your composer.json file:
{
"require": {
"doctrine/orm": "*"
}
}
然后从命令行调用composer install。
Then call composer install from your command line.
与CodeIgniter集成
以下是步骤：
将php文件添加到名为Doctrine.php的系统/应用程序/库文件夹中。这将是D2实体管理器的包装/引导。
将Doctrine文件夹（包含Common，DBAL和ORM的文件夹）放在third_party文件夹中。
如果需要，打开你的config / autoload.php文件，并自动加载你的Doctrine库： $ autoload ['libraries'] = array（'doctrine'）;
创建您的Doctrine CodeIgniter库
现在，这里是你的教义。 php文件应该看起来像。根据您的需要自定义。
Now, here is what your Doctrine.php file should look like. Customize it to your needs.
<?php
/**
* Doctrine 2.4 bootstrap
*
*/
use Doctrine\Common\ClassLoader,
Doctrine\ORM\Configuration,
Doctrine\ORM\EntityManager,
Doctrine\Common\Cache\ArrayCache,
Doctrine\DBAL\Logging\EchoSQLLogger;
class Doctrine {
public $em = null;
public function __construct()
{
// load database configuration from CodeIgniter
require_once APPPATH.'config/database.php';
// include Doctrine's ClassLoader class
require_once APPPATH.'third_party/Doctrine/Common/ClassLoader.php';
// load the Doctrine classes
$doctrineClassLoader = new ClassLoader('Doctrine', APPPATH.'third_party');
$doctrineClassLoader->register();
// load the entities
$entityClassLoader = new ClassLoader('Entities', APPPATH.'models');
$entityClassLoader->register();
// load the proxy entities
$proxiesClassLoader = new ClassLoader('Proxies', APPPATH.'models/proxies');
$proxiesClassLoader->register();
// load Symfony2 classes
// this is necessary for YAML mapping files and for Command Line Interface (cli-doctrine.php)
$symfonyClassLoader = new ClassLoader('Symfony', APPPATH.'third_party/Doctrine');
$symfonyClassLoader->register();
// Set up the configuration
$config = new Configuration;
// Set up caches
if(ENVIRONMENT == 'development') // set environment in index.php
// set up simple array caching for development mode
$cache = new \Doctrine\Common\Cache\ArrayCache;
else
// set up caching with APC for production mode
$cache = new \Doctrine\Common\Cache\ApcCache;
$config->setMetadataCacheImpl($cache);
$config->setQueryCacheImpl($cache);
// set up annotation driver
$driver = new \Doctrine\ORM\Mapping\Driver\PHPDriver(APPPATH.'models/Mappings');
$config->setMetadataDriverImpl($driver);
// Proxy configuration
$config->setProxyDir(APPPATH.'/models/Proxies');
$config->setProxyNamespace('Proxies');
// Set up logger
$logger = new EchoSQLLogger;
$config->setSQLLogger($logger);
$config->setAutoGenerateProxyClasses( TRUE ); // only for development
// Database connection information
$connectionOptions = array(
'driver' => 'pdo_mysql',
'user' => $db['default']['username'],
'password' => $db['default']['password'],
'host' => $db['default']['hostname'],
'dbname' => $db['default']['database']
);
// Create EntityManager, and store it for use in our CodeIgniter controllers
$this->em = EntityManager::create($connectionOptions, $config);
}
}
设置命令行工具
Setting up the Command Line Tool
学说附带了许多在开发过程中非常有帮助的命令行工具。
Doctrine ships with a number of command line tools that are very helpful during development.
检查Doctrine.php文件中是否存在这些行，以加载使用命令行工具（和YAML映射文件）的Symfony类：
Check if these lines exists in the Doctrine.php file, to load Symfony classes for using the Command line tools (and for YAML mapping files):
$symfonyClassLoader = new ClassLoader('Symfony', APPPATH.'third_party/Doctrine');
$symfonyClassLoader->register();
您需要将应用程序EntityManager注册到控制台工具，以通过创建cli来使用任务-doctrine.php文件在应用程序目录中，具有以下内容：
You need to register your applications EntityManager to the console tool to make use of the tasks by creating a cli-doctrine.php file in the application directory with the following content:
<?php
/**
* Doctrine CLI bootstrap for CodeIgniter
*
*/
define('APPPATH', dirname(__FILE__) . '/');
define('BASEPATH', APPPATH . '/../system/');
define('ENVIRONMENT', 'development');
require APPPATH.'libraries/Doctrine.php';
$doctrine = new Doctrine;
$em = $doctrine->em;
$helperSet = new \Symfony\Component\Console\Helper\HelperSet(array(
'db' => new \Doctrine\DBAL\Tools\Console\Helper\ConnectionHelper($em->getConnection()),
'em' => new \Doctrine\ORM\Tools\Console\Helper\EntityManagerHelper($em)
));
\Doctrine\ORM\Tools\Console\ConsoleRunner::run($helperSet);
?>
现在，通过PHP命令行运行此脚本，并且可以看到可用的命令列表。
Now run this script through the PHP command-line and should see a list of commands available to you.
php cli-doctrine.php
从数据库生成映射类：
php cli-doctrine.php orm:convert-mapping --from-database annotation models/Entities
如果您收到此错误：
致命错误：调用未定义的函数Doctrine\Common\Cache\apc_fetch（）
为PHP安装APC扩展名：
if you get this error: Fatal error: Call to undefined function Doctrine\Common\Cache\apc_fetch() install the APC extension for PHP:
sudo apt-get install php-apc
sudo /etc/init.d/apache2 restart
对于生产模式，您将需要使用像APC这样的真正的缓存系统，摆脱 EchoSqlLogger ，并在Doctrine.php中关闭 autoGenerateProxyClasses
For production mode you'll want to use a real caching system like APC, get rid of EchoSqlLogger, and turn off autoGenerateProxyClasses in Doctrine.php
