我正在使用 Symfony2 创建一些虚拟项目。我遵守 Symfony2 Book 文档以使用 Doctrine 命令行 ( http://symfony.com/doc/current/book/doctrine.html#add-mapping-information ) 创建实体。因此,我使用的是注释、普通实体Product并且没有关联。
我已经复制了确切的示例:我已经成功创建了数据库并创建了表 Product。然后,我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!),这只是为了测试目的。Doctrine 不能生成更多的 getter 和 setter,也不能在 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 文档中的代码完全相同,只是 Bundle 名称改为 MyBundle。文件和文件夹的结构与其他功能一起正常工作。该项目没有特定的设置,只有基本设置。
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;
}
已经尝试过
- 更改项目权限
- 以 root 身份执行“应用程序/控制台原则:生成:实体”
- 清除缓存
- 执行缓存:清除和缓存:预热
- 手动删除缓存文件夹
- 在 Product 实体中只保留 id(作为主键)
- 删除并重新创建整个数据库
- 删除产品实体,清除缓存并重新创建所有内容(手动)
- 更新所有供应商
- 检查了所有双**的注释
- 更换具有相同软件架构的计算机
- 我还执行了(感谢@Srdjan) php app/console 学说:cache:clear-metadata && app/console 学说:cache:clear-query && app/console 学说:cache:clear-result 但不会生成 getter 和 setter
- 我已逐步删除表、数据库并重新创建(感谢@paistra)
我试图删除表格
应用程序/控制台原则:架构:drop
但错误总是一样的
[Doctrine\ORM\Mapping\MappingException]
No identifier/primary key specified for Entity "MyBundle\Entity\Product".
Every Entity must have an identifier/primary key.
即使表不存在..
谢谢您的帮助
