Symfony2自动生成实体错误

Question

我有两个表news和news_category。为此，我使用symfony命令"doctrine:mapping:convert"创建了两个映射类。两个文件如下:

1. news.orm.yml .

   News:
      type: entity
      table: news
      fields:
         newsId:
             id: true
             type: integer
             unsigned: false
             nullable: false
             column: news_id
             generator:
                  strategy: IDENTITY
        newsTitle:
            type: string
            length: 255
            fixed: false
            nullable: false
            column: news_title
        newsDescription:
            type: text
            nullable: false
            column: news_description
        newsStatus:
            type: string
            length: 255
            fixed: false
            nullable: false
            column: news_status
        createdAt:
            type: date
            nullable: false
            column: created_at
       manyToOne:
       category:
            targetEntity: NewsCategory
            cascade: {  }
            mappedBy: null
            inversedBy: null
            joinColumns:
               category_id:
                   referencedColumnName: category_id
            orphanRemoval: false
   lifecycleCallbacks: {  }
   

2)。NewCategory.orm.yml

NewsCategory:
type: entity
table: news_category
fields:
    categoryId:
        id: true
        type: integer
        unsigned: false
        nullable: false
        column: category_id
        generator:
            strategy: IDENTITY
    categoryTitle:
        type: string
        length: 255
        fixed: false
        nullable: false
        column: category_title
    categoryDescription:
        type: text
        nullable: false
        column: category_description
lifecycleCallbacks: {  }

之后，我使用了另一个symfony命令"doctrine:mapping:import"，使用这个，我再次在实体文件夹News.php和newcategory .php中生成两个文件

如下所示。

1) news.php

<?php
  namespace AdminNewsBundleEntity;
  use DoctrineORMMapping as ORM;
 /**
  * News
  *
  * @ORMTable(name="news")
  * @ORMEntity
  */
  class News
 {
/**
 * @var integer
 *
 * @ORMColumn(name="news_id", type="integer", nullable=false)
 * @ORMId
 * @ORMGeneratedValue(strategy="IDENTITY")
 */
private $newsId;
/**
 * @var string
 *
 * @ORMColumn(name="news_title", type="string", length=255, nullable=false)
 */
private $newsTitle;
/**
 * @var string
 *
 * @ORMColumn(name="news_description", type="text", nullable=false)
 */
private $newsDescription;
/**
 * @var string
 *
 * @ORMColumn(name="news_status", type="string", length=255, nullable=false)
 */
private $newsStatus;
/**
 * @var DateTime
 *
 * @ORMColumn(name="created_at", type="date", nullable=false)
 */
private $createdAt;
/**
 * @var NewsCategory
 *
 * @ORMManyToOne(targetEntity="NewsCategory")
 * @ORMJoinColumns({
 *   @ORMJoinColumn(name="category_id", referencedColumnName="category_id")
 * })
 */
private $category;
}

2) NewCategory.php

namespace AdminNewsBundleEntity;
use DoctrineORMMapping as ORM;
/**
 * NewsCategory
 *
 * @ORMTable(name="news_category")
 * @ORMEntity
 */
class NewsCategory
{
/**
 * @var integer
 *
 * @ORMColumn(name="category_id", type="integer", nullable=false)
 * @ORMId
 * @ORMGeneratedValue(strategy="IDENTITY")
 */
private $categoryId;
/**
 * @var string
 *
 * @ORMColumn(name="category_title", type="string", length=255, nullable=false)
 */
private $categoryTitle;
/**
 * @var string
 *
 * @ORMColumn(name="category_description", type="text", nullable=false)
 */
private $categoryDescription;
}

问题是现在当我使用"doctrine:generate: Entities"创建实体时它给了我以下错误:

D:wampwwwSymfony>php app/console doctrine:generate:entities AdminNewsBundle
Generating entities for bundle "AdminNewsBundle"
  [DoctrineCommonPersistenceMappingMappingException]
  Invalid mapping file 'Admin.NewsBundle.Entity.News.orm.yml' for class 'Admi
  nNewsBundleEntityNews'.
 doctrine:generate:entities [--path="..."] [--no-backup] name

对不起，我的英语不好，请帮助我解决这个问题，因为我是新的symfony2

Answer 1

尝试:

1) php app/console doctrine:mapping:convert yml ./src/Admin/NewsBundle/Resources/config/doctrine/metadata/orm --from-database --force --namespace="Admin\NewsBundle\Entity\"

for Linux 命名空间="Admin\NewsBundle\Entity\" for Win probably 命名空间="AdminNewsBundleEntity\"

注意映射在正确的位置，具有正确的名称和正确的语法。

2) php app/console doctrine:mapping:import AdminNewsBundle annotation
3) php app/console doctrine:generate:entities AdminNewsBundle

Answer 2

尝试用nspace

替换实体名称的第一行YML

AdminNewsBundleEntityNews:

比如

。
