Propel

Question

我正在努力获得连接到数据库的动力。我使用 propel reverse "..." 创建了类和 table 映射，并创建了以下结构：

propel.ini

[propel]

# A better Pluralizer
propel.builder.pluralizer.class = builder.util.StandardEnglishPluralizer

propel.xml

<?xml version="1.0" encoding="ISO-8859-1" standalone="no"?>
<config>
    <propel>
        <general>
           <project>PHP-PlayArea</project>
           <version>2.0.0-dev</version>
        </general>
        <database>
            <connections>
                <connection id="default">
                    <adapter>mysql</adapter>
                    <classname>Propel\Runtime\Connection\ConnectionWrapper</classname>
                    <dsn>mysql:host=localhost;dbname=test</dsn>
                    <user>me</user>
                    <password>blahblahblah</password>
                    <settings>
                        <charset>utf8</charset>
                    </settings>
                </connection>
            </connections>
        </database>
        <runtime>
            <defaultConnection>default</defaultConnection>
            <connection>default</connection>
        </runtime>
        <generator>
            <defaultConnection>default</defaultConnection>
            <connection>default</connection>
        </generator>
    </propel>
</config>

Propel.php

<?php namespace propel;

use Propel\Runtime\Propel;

Propel::init("../propel/propel.xml");

我有以下失败的单元测试：

// Include the main Propel script
require_once '../propel/Propel.php';

require_once '../propel/Base/Users.php';
require_once '../propel/Map/UsersTableMap.php';
require_once '../propel/Users.php';

use propel\Users;

const name = 'gareth';

class PropelTests extends \PHPUnit_Framework_TestCase {
    public function testAddUser()
    {
        // create a user ?
        $user = new Users();
        // brings back an empty config
        $manager = new ConfigurationManager();
        //Get the array of runtime configured connections
        $connections = $manager->get();

        // *** fails here ***
        // test connections
        $con = Propel::getWriteConnection(UsersTableMap::DATABASE_NAME);
        $con = Propel::getReadConnection(UsersTableMap::DATABASE_NAME);

输出；

C:\wamp\bin\php\php5.5.12\php.exe -dxdebug.remote_enable=1 -dxdebug.remote_mode=req -dxdebug.remote_port=9000 -dxdebug.remote_host=127.0.0.1 C:\Users\gareth\AppData\Local\Temp\ide-phpunit.php --no-configuration Tests\PropelTests C:\Development\PHP-PlayArea\Tests\Propel.Tests.php

    </propel>
</config>

No connection defined for database "default". Did you forget to define a connection or is it wrong written?
 C:\Development\PHP-PlayArea\vendor\propel\propel\src\Propel\Runtime\ServiceContainer\StandardServiceContainer.php:279
 C:\Development\PHP-PlayArea\vendor\propel\propel\src\Propel\Runtime\ServiceContainer\StandardServiceContainer.php:355
 C:\Development\PHP-PlayArea\propel\Base\Users.php:655
 C:\Development\PHP-PlayArea\Tests\Propel.Tests.php:29

有什么想法吗？我有点难过...我的配置看起来不错，但显然不是。

更新：2015/07/06 13:01：调试后它看起来像炸毁了，因为找不到连接管理器

Answer 1

您在 propel.xml 的下一行中缺少端口号：

 <dsn>mysql:host=localhost:<<port number>>;dbname=test</dsn>

如果您从现有模式进行逆向工程，还要检查 schema.xml 中的数据库名称。确保它不是空白的。

Answer 2

我刚开始学习 Propel，我遇到了完全相同的问题。

我试过你在这里做的事情：

Propel::init("../propel/propel.xml");

所做的只是包含文件并将内容打印到输出中，就像在输出中一样。

我终于通过有效地将您的 Propel.php 替换为：

使其正常工作

<?php

use Propel\Common\Config\ConfigurationManager;
use Propel\Runtime\Connection\ConnectionManagerSingle;
use Propel\Runtime\Propel;

// Load the configuration file 
$configManager = new ConfigurationManager( '../propel/propel.xml' );

// Set up the connection manager
$manager = new ConnectionManagerSingle();
$manager->setConfiguration( $configManager->getConnectionParametersArray()[ 'default' ] );
$manager->setName('default');

// Add the connection manager to the service container
$serviceContainer = Propel::getServiceContainer();
$serviceContainer->setAdapterClass('default', 'mysql');
$serviceContainer->setConnectionManager('default', $manager);
$serviceContainer->setDefaultDatasource('default');

希望对您有所帮助

Propel - 没有为数据库定义连接 "default"

Propel - No connection defined for database "default"
