我正在使用Symfony2来创建一些虚拟项目。我保留Symfony2 Book文档以创建一个带有Doctrine命令行的实体(http://symfony.com/doc/current/book/doctrine.html#add-mapping-information)。因此,我使用注释,普通实体产品而没有关联。
我已经复制了确切的示例:我已成功创建数据库并创建了表Product。然后,我已经删除了所有内容并尝试重新创建数据库(一切都很好)和表(问题!),仅用于测试目的。 Doctrine不能再生成getter和setter,也无法在MySQL数据库上创建表。
这里有一些输出
app/console doctrine:generate:entities MyBundle
> backing up Product.php to Product.php~
> generating MyBundle\Entity\Product
(nothing happens except for creating the identical backup file with no setters / getters added)
-
app/console doctrine:schema:validate
OR
app/console doctrine:schema:create
OR
app/console doctrine:schema:update --force
----------
[Doctrine\ORM\Mapping\MappingException]
No identifier/primary key specified for Entity "MyBundle\Entity\Product".
Every Entity must have an identifier/primary key.
doctrine:schema:validate [--em[="..."]]

我的代码
我的代码与Symfony2 Book文档完全相同,但Bundle名称除外,更改为MyBundle。文件和文件夹的结构与其他功能一起正常工作。项目没有特定的设置,只有基础。
namespace MyBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* @ORM\Entity
* @ORM\Table(name="product")
*/
class Product
{
/**
* @ORM\Column(type="integer")
* @ORM\Id
* @ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* @ORM\Column(type="string", length=100)
*/
protected $name;
/**
* @ORM\Column(type="decimal", scale=2)
*/
protected $price;
/**
* @ORM\Column(type="text")
*/
protected $description;
}
已尝试
我试图用
删除表格app / console doctrine:schema:drop
但错误始终相同
[Doctrine\ORM\Mapping\MappingException]
No identifier/primary key specified for Entity "MyBundle\Entity\Product".
Every Entity must have an identifier/primary key.
即使表格不存在..
感谢您的帮助

如果已将映射转换为xml / yml的注释,请务必删除旧的映射文件。
在此示例中运行:AppBundle\Resources\config\doctrine\MyEntity.doctrine.xml
转换:AppBundle\Entity\MyEntity.php
与此文件内联的注释:gmail.com
错误是因为它在使用注释之前使用xml映射。 删除xml,应该很好。

在项目检查实体中,产品的定义与示例相同(注释@ORM ...)
在进行新测试时也尝试删除表格产品
// src/AppBundle/Entity/Product.php
namespace AppBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* @ORM\Entity
* @ORM\Table(name="product")
*/
class Product
{
/**
* @ORM\Column(type="integer")
* @ORM\Id
* @ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* @ORM\Column(type="string", length=100)
*/
protected $name;
/**
* @ORM\Column(type="decimal", scale=2)
*/
protected $price;
/**
* @ORM\Column(type="text")
*/
protected $description;
}

如果您对实体类进行了更改,则还必须清除Doctrine缓存:
php app/console doctrine:cache:clear-metadata && app/console doctrine:cache:clear-query && app/console doctrine:cache:clear-result

是的,我的产品实体与您报告的实体完全相同
namespace MyBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* @ORM\Entity
* @ORM\Table(name="product")
*/
class Product
{
/**
* @ORM\Column(type="integer")
* @ORM\Id
* @ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* @ORM\Column(type="string", length=100)
*/
protected $name;
/**
* @ORM\Column(type="decimal", scale=2)
*/
protected $price;
/**
* @ORM\Column(type="text")
*/
protected $description;
}
