[英]Register custom Doctrine type in Symfony4
So I have this custom Doctrine type所以我有这个自定义的 Doctrine 类型
namespace App\\Doctrine\\Types;命名空间 App\\Doctrine\\Types;
use Doctrine\\DBAL\\Platforms\\AbstractPlatform;使用 Doctrine\\DBAL\\Platforms\\AbstractPlatform; use Doctrine\\DBAL\\Types\\TextType;
使用 Doctrine\\DBAL\\Types\\TextType;
class MyType extends TextType
{
private $prefix='';
public function getName()
{
return 'my_type';
}
public function setPrefix(string $prefix)
{
$this->prefix=$prefix;
}
}
I registerd in in the config/packages/doctrine.yml:我在 config/packages/doctrine.yml 中注册:
doctrine:
dbal:
types:
my_type: App\Doctrine\Types\MyType
Then in Kernel boot() I'm trying to add some parameters to this type:然后在 Kernel boot() 中,我尝试向这种类型添加一些参数:
public function boot() {
parent::boot();
$myType=Type::getType('my_type');
$myType->setPrefix('abc');
}
This works perfectly the first time I run the app.这在我第一次运行该应用程序时非常有效。 The prefix is set for the type and can be used through the whole app.
前缀是为类型设置的,可以在整个应用程序中使用。 However, the second time I get an Exception:
但是,我第二次遇到异常:
Unknown column type "encrypted_text" requested.
请求了未知的列类型“encrypted_text”。 Any Doctrine type that you use has to be registered with \\Doctrine\\DBAL\\Types\\Type::addType().
您使用的任何 Doctrine 类型都必须使用 \\Doctrine\\DBAL\\Types\\Type::addType() 进行注册。 You can get a list of all the known types with \\Doctrine\\DBAL\\Types\\Type::getTypesMap().
您可以使用 \\Doctrine\\DBAL\\Types\\Type::getTypesMap() 获取所有已知类型的列表。 If this error occurs during database introspection then you might have forgotten to register all database types for a Doctrine Type.
如果在数据库内省期间发生此错误,那么您可能忘记为 Doctrine 类型注册所有数据库类型。 Use AbstractPlatform#registerDoctrineTypeMapping() or have your custom types implement Type#getMappedDatabaseTypes().
使用 AbstractPlatform#registerDoctrineTypeMapping() 或让您的自定义类型实现 Type#getMappedDatabaseTypes()。 If the type name is empty you might have a problem with the cache or forgot some mapping information.
如果类型名称为空,则可能是缓存有问题或忘记了一些映射信息。
I then changed boot() to :然后我将 boot() 更改为:
public function boot() {
parent::boot();
if (!Type::hasType('my_type')) {
Type::addType('my_type', 'App\Doctrine\Types\MyType');
}
$myType=Type::getType('my_type');
$myType->setPrefix('abc');
}
Now the exception is gone, but the prefix is not set.现在异常消失了,但没有设置前缀。 I know the exceptions gives me information about what to do but I really don't know where to start.
我知道异常给了我关于做什么的信息,但我真的不知道从哪里开始。
Can anyone point me in the right direction?任何人都可以指出我正确的方向吗?
For now I fixed it by removing it from config/packages/doctrine.yml so it's not registered there anymore.现在我通过从 config/packages/doctrine.yml 中删除它来修复它,所以它不再在那里注册。 In Kernel I can now load it:
在内核中,我现在可以加载它:
public function boot() {
parent::boot();
if (!Type::hasType('my_type')) {
Type::addType('my_type', 'App\Doctrine\Types\MyType');
}
$myType = Type::getType('my_type');
$myType->setPrefix('abc');
}
I still can't really understand why this works before building the cache but not once the cache is build.我仍然无法真正理解为什么这在构建缓存之前有效,但在构建缓存后就不行了。 But well, I can continue now.
不过好吧,我现在可以继续了。
If someone has a better answer, I'd be more than happy to accept it.如果有人有更好的答案,我很乐意接受。
#This is may answer!!!
**IMPORTANTE!! Because in Symfony/PHP (NO Object Oriented Language) don't storaging a state it's need make this form to mapping an ENUM type or any Custom Type similary to ENUM.**
For customize and mapping you types as Enum in DB table, you need to have a higher version Symfony >= 4.4 for to use this Bundle.为了自定义和映射您在 DB 表中键入的 Enum,您需要有更高版本的 Symfony >= 4.4 才能使用此 Bundle。 Execute it in your project (command prompt)
在您的项目中执行它(命令提示符)
composer req fresh/doctrine-enum-bundle
Link example --> [https://github.com/fre5h/DoctrineEnumBundle][1] .
I made do this and it's ok for my app.
So, copy this class from this link
[https://github.com/fre5h/DoctrineEnumBundle/blob/master/DBAL/Types/AbstractEnumType.php][1]
and storage it in src/DBAL/Types =(IF NOT EXIST, CREATE IT), in your project Symfony => 4.4 o higher version.
#This is your Base class type.
Create this Table in Your Database (in my case I'm using MySql DB):
CREATE TABLE players (
id INT AUTO_INCREMENT NOT NULL,
position ENUM('PG', 'SG', 'SF', 'PF', 'C') NOT NULL,
PRIMARY KEY(id)
) DEFAULT CHARACTER SET utf8 COLLATE utf8_unicode_ci ENGINE = INNODB
*****************
Create an Entity class for mapping table (Players) from your Databae inside your project level directory.
D:SYMFONY\app\myApp
php bin/console doctrine:mapping:import "App\Entity" annotation --path=src/Entity --filter="Players"
Create getter and setters for your new Entity:
D:SYMFONY\app\myApp
php bin/console make:entity --regenerate App
Generate your CRUD operation for Entty class + frontend.
D:SYMFONY\app\myApp
php bin/console make:entity --regenerate App
Create your custom Type class BasketballPositionType
<?php
namespace App\DBAL\Types;
use Fresh\DoctrineEnumBundle\DBAL\Types\AbstractEnumType;
final class BasketballPositionType extends AbstractEnumType
{
public const POINT_GUARD = 'PG';
public const SHOOTING_GUARD = 'SG';
public const SMALL_FORWARD = 'SF';
public const POWER_FORWARD = 'PF';
public const CENTER = 'C';
protected static $choices = [
self::POINT_GUARD => 'Point Guard',
self::SHOOTING_GUARD => 'Shooting Guard',
self::SMALL_FORWARD => 'Small Forward',
self::POWER_FORWARD => 'Power Forward',
self::CENTER => 'Center'
];
}
Go inside this path in your Symfony project at
D:SYMFONY\app\myApp\config\packages
and create this class php : doctrime.php.
This class it's necesary for to Register your new Type.
Can you find more information at link for register new type in synfony
[https://symfony.com/doc/current/doctrine/dbal.html][1]
so - REGISTER YOUR NEW TYPE
Copy this fragment of code end paste in doctrime.php class:
<?php
$container->loadFromExtension('doctrine', [
'dbal' => [
'mapping_types' => [
'enum' => 'string', /////////mapping enum to as stringa
],
'types' => [
'BasketballPositionType' => App\DBAL\Types\BasketballPositionType::class,
],
],
]);
So, bindig ENUM type db in String and your new Type is "BasketballPositionType" !!!!
Now, use your Custom Type in your Entity Class mapping 'Players'.
<?php
namespace App\Entity;
** very important
use App\DBAL\Types\BasketballPositionType;
use Fresh\DoctrineEnumBundle\Validator\Constraints as DoctrineAssert;
use Doctrine\ORM\Mapping as ORM;
/**
* Players
*
* @ORM\Table(name="players")
* @ORM\Entity
*/
class Players
{
/**
* @var int
*
* @ORM\Column(name="id", type="integer", nullable=false)
* @ORM\Id
* @ORM\GeneratedValue(strategy="IDENTITY")
*/
private $id;
/**
* @var string
*
* @ORM\Column(name="position", type="BasketballPositionType", length=255, nullable=false)
* @DoctrineAssert\Enum(entity="App\DBAL\Types\BasketballPositionType")
*/
private $position;
public function getId(): ?int
{
return $this->id;
}
public function getPosition(): ?string
{
return $this->position;
}
public function setPosition(string $position): self
{
$this->position = $position;
return $this;
}
}

Run you Symfony embeded server
[ symfony serve ]
And go later in browser at https://127.0.0.1:8000/players
I'm use CMDER prompt command because it has Git incorporated.
It's very easy!!
