我不希望将成就的困难和描述存储在数据库中，只存储在 .yml 文件中，除非有充分的理由将成就本身存储在数据库中，以及将静态数据导入数据库的好方法自动部署的一部分。
Users一个很好的理由：管理和之间的关系会更容易Achievements。
一种将静态数据导入数据库的方法：DoctrineFixturesBundle
1.定义你的静态配置
最好的方法是公开语义配置。
在您的情况下，您将拥有以下 2 个文件：
// src/Paulpro/ExperimentingBundle/DependencyExtension/Configuration.php
<?php
namespace Paulpro\ExperimentingBundle\DependencyInjection;
use Symfony\Component\Config\Definition\Builder\TreeBuilder;
use Symfony\Component\Config\Definition\ConfigurationInterface;
class Configuration implements ConfigurationInterface
{
/**
* Defines the configuration tree for the bundle
*
* @return \Symfony\Component\Config\Definition\Builder\TreeBuilder
*/
public function getConfigTreeBuilder()
{
$treeBuilder = new TreeBuilder();
$rootNode = $treeBuilder->root('paulpro_experimenting');
$rootNode
->children()
->arrayNode('Achievements')->addDefaultsIfNotSet()
->children()
->arrayNode('Conservative')->addDefaultsIfNotSet()
->children()
->integerNode('Difficulty')->defaultValue(2)->end()
->scalarNode('Description')->defaultValue('Description of Conservative Achievement.')->end()
->end()
->end()
->arrayNode('Dedicated')->addDefaultsIfNotSet()
->children()
->integerNode('Difficulty')->defaultValue(3)->end()
->scalarNode('Description')->defaultValue('Description of Dedicated Achievement.')->end()
->end()
->end()
->arrayNode('Persistent')->addDefaultsIfNotSet()
->children()
->integerNode('Difficulty')->defaultValue(2)->end()
->scalarNode('Description')->defaultValue('Description of Persistent Achievement.')->end()
->end()
->end();
return $treeBuilder;
}
}
和：
<?php
namespace Paulpro\ExperimentingBundle\DependencyInjection;
use Symfony\Component\DependencyInjection\ContainerBuilder;
use Symfony\Component\HttpKernel\DependencyInjection\Extension;
class PaulproExperimentingExtension extends Extension
{
/**
* Load the configuration for the bundle
*
* @param array $configs
* @param \Symfony\Component\DependencyInjection\ContainerBuilder $container
*/
public function load(array $configs, ContainerBuilder $container)
{
$configuration = new Configuration();
$config = $this->processConfiguration($configuration, $configs);
foreach($config as $key => $value)
{
$container->setParameter('paulpro_experimenting.'.$key, $value);
}
}
}
这样做，您将能够更好地管理用户如何使用配置。要查看默认配置结果的示例，可以使用以下命令：
php app/console config:dump-reference PaulProExperimentingBundle
结果应该如下：
Default configuration for "PaulProExperimentingBundle"
paulpro_experimenting:
Achievements:
Conservative:
Difficulty: 2
Description: Description of Conservative Achievement.
Dedicated:
Difficulty: 3
Description: Description of Dedicated Achievement.
Persistent:
Difficulty: 2
Description: Description of Persistent Achievement.
这意味着您的用户可以将此示例放在文件夹config.yml下，app\config并根据需要进行更改。唯一的条件是，他们放入此文件中的任何信息都必须通过Configuration您定义的树进行验证。
2. 定义你的实体
定义Achievement最适合您需要的实体。例如，您可以使用：
// src/Paulpro/ExperimentingBundle/Entity/Achievement.php
namespace Paulpro\ExperimentingBundle\Entity;
use Doctrine\Common\Collections\ArrayCollection;
class Achievement{
protected $name;
protected $difficulty;
protected $description;
/**
* @ManyToMany(targetEntity="User", mappedBy="achievements")
* @JoinTable(name="users_achievements")
**/
private $users;
public function __construct() {
$this->users = new ArrayCollection();
}
}
您将保持User实体原样，除非您必须将关系添加到Achievement：
// src/Paulpro/ExperimentingBundle/Entity/User.php
namespace Paulpro\ExperimentingBundle\Entity;
use Doctrine\Common\Collections\ArrayCollection;
class User {
protected $name;
/**
* @ManyToMany(targetEntity="Achivement", mappedBy="users")
**/
protected $achievements;
public function __construct(){
$this->achievements = new ArrayCollection();
}
}
3. 部署应用时填写数据库
这是最后一步，它专门使用DoctrineFixturesBundle。
您必须为您的Achivement实体创建夹具：
// src/Paulpro/ExperimentingBundle/DataFixtures/ORM/LoadAchivementData.php
<?php
namespace Paulpro\ExperimentingBundle\DataFixtures\ORM;
use Doctrine\Common\DataFixtures\FixtureInterface;
use Doctrine\Common\Persistence\ObjectManager;
use Paulpro\ExperimentingBundle\Entity\Achivement;
use Symfony\Component\DependencyInjection\ContainerAwareInterface;
use Symfony\Component\DependencyInjection\ContainerInterface;
class LoadTypesData implements FixtureInterface, ContainerAwareInterface
{
private $container;
public function setContainer(ContainerInterface $container = null)
{
$this->container = $container;
}
public function load(ObjectManager $manager)
{
foreach($this->container->getParameter('paulpro_experimenting.Achievements') as $key => $value)
{
$achivement = new Achivement();
$achivement->setName($key);
$achivement->setDifficulty($value['Difficulty']);
$achivement->setDescription($value['Description']);
$manager->persist($achivement);
}
$manager->flush();
}
}
该夹具将通过配置并从此处paulpro_experimenting.Achievements加载定义的内容。
最后，要将数据加载到数据库中，您必须运行以下命令：Achievements
php app/console doctrine:fixtures:load
等等，你现在应该可以achievements从你的users.
