【问题描述】:
我按照这个例子:
https://symfony.com/doc/current/doctrine/associations.html
但是当我制作时:
php bin/console make:migration
这是我的迁移文件:
<?php
declare(strict_types=1);
namespace DoctrineMigrations;
use Doctrine\DBAL\Schema\Schema;
use Doctrine\Migrations\AbstractMigration;
/**
* Auto-generated Migration: Please modify to your needs!
*/
final class Version20191121114152 extends AbstractMigration
{
public function getDescription() : string
{
return '';
}
public function up(Schema $schema) : void
{
// this up() migration is auto-generated, please modify it to your needs
$this->abortIf($this->connection->getDatabasePlatform()->getName() !== 'mysql', 'Migration can only be executed safely on \'mysql\'.');
$this->addSql('CREATE TABLE category (id INT AUTO_INCREMENT NOT NULL, PRIMARY KEY(id)) DEFAULT CHARACTER SET utf8mb4 COLLATE `utf8mb4_unicode_ci` ENGINE = InnoDB');
$this->addSql('CREATE TABLE product (id INT AUTO_INCREMENT NOT NULL, PRIMARY KEY(id)) DEFAULT CHARACTER SET utf8mb4 COLLATE `utf8mb4_unicode_ci` ENGINE = InnoDB');
}
public function down(Schema $schema) : void
{
// this down() migration is auto-generated, please modify it to your needs
$this->abortIf($this->connection->getDatabasePlatform()->getName() !== 'mysql', 'Migration can only be executed safely on \'mysql\'.');
$this->addSql('DROP TABLE category');
$this->addSql('DROP TABLE product');
}
}
Doctrine 在 id 字段之后停止。他没有看到其他人。
有人遇到过这个问题吗?
我的配置是:
- Wamp(Windows 10、MySQL 5.7)
- Symfony 4.3
我的实体类:
Category.php
<?php
namespace App\Entity;
use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\Common\Collections\Collection;
use Doctrine\ORM\Mapping as ORM;
/**
* @ORM\Entity(repositoryClass="App\Repository\CategoryRepository")
*/
class Category
{
/**
* @ORM\Id()
* @ORM\GeneratedValue()
* @ORM\Column(type="integer")
*/
private $id;
/**
* @ORM\Column(type="string", length=255)
*/
private $name;
/**
* @ORM\ManyToMany(targetEntity="App\Entity\Product", mappedBy="category")
*/
private $products;
public function __construct()
{
$this->products = new ArrayCollection();
}
public function getId(): ?int
{
return $this->id;
}
public function getName(): ?string
{
return $this->name;
}
public function setName(string $name): self
{
$this->name = $name;
return $this;
}
/**
* @return Collection|Product[]
*/
public function getProducts(): Collection
{
return $this->products;
}
public function addProduct(Product $product): self
{
if (!$this->products->contains($product)) {
$this->products[] = $product;
$product->addCategory($this);
}
return $this;
}
public function removeProduct(Product $product): self
{
if ($this->products->contains($product)) {
$this->products->removeElement($product);
$product->removeCategory($this);
}
return $this;
}
}
产品.php
<?php
namespace App\Entity;
use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\Common\Collections\Collection;
use Doctrine\ORM\Mapping as ORM;
/**
* @ORM\Entity(repositoryClass="App\Repository\ProductRepository")
*/
class Product
{
/**
* @ORM\Id()
* @ORM\GeneratedValue()
* @ORM\Column(type="integer")
*/
private $id;
/**
* @ORM\ManyToMany(targetEntity="App\Entity\Category", inversedBy="products")
*/
private $category;
public function __construct()
{
$this->category = new ArrayCollection();
}
public function getId(): ?int
{
return $this->id;
}
/**
* @return Collection|Category[]
*/
public function getCategory(): Collection
{
return $this->category;
}
public function addCategory(Category $category): self
{
if (!$this->category->contains($category)) {
$this->category[] = $category;
}
return $this;
}
public function removeCategory(Category $category): self
{
if ($this->category->contains($category)) {
$this->category->removeElement($category);
}
return $this;
}
}
【问题讨论】:
-
欢迎!对于您的问题,如果您可以通过
artisan migrate命令或artisan migrate:refresh向我们提供迁移本身的执行方式,将会更有帮助。 -
能否包含您的实体类、它们的映射以及您遇到的任何错误?
-
@Kyrre 我添加了实体类。我没有看到任何错误。
