来自doctrine.yaml：

# /config/packages/doctrine.yaml
doctrine:
    dbal:
        default_connection: training
        connections:
            training:
                dbname:   "training"
                driver:   "pdo_mysql"
                host:     "localhost"
                port:     "3306"
                user:     "userdb"
                password: "XXXXXXXXXX"
                charset:  UTF8
                mapping_types:
                    bit: boolean
    orm:
        auto_generate_proxy_classes: "%kernel.debug%"
        default_entity_manager: training
        entity_managers:
            training:
                connection: training
                auto_mapping: true

命令：

php bin/console doctrine:mapping:import --em=training App\Entity annotation --path=src/Entity

生成src/Entity Course.php实体：

<?php

namespace App\Entity;

use Doctrine\ORM\Mapping as ORM;

/**
 * Course
 *
 * @ORM\Table(name="course", indexes={@ORM\Index(name="id_product_idx_1", columns={"id_product"}), @ORM\Index(name="enabled_idx_1", columns={"enabled"}), @ORM\Index(name="sort_idx_1", columns={"sort"})})
 * @ORM\Entity
 */
class Course
{
    ....

进入控制台后：

php bin/console make:entity --regenerate App

这失败并出现错误：

在＆＃34; App＆＃34;中没有找到任何实体。命名空间

同样适用于

php bin/console make:entity --regenerate App\Entity

如果我尝试

php bin/console make:entity --regenerate App\Entity\Course

输出

无法找到＆＃34; App \ Entity \ Course＆＃34;的Doctrine元数据。它是否被映射为实体？

我做错了什么？

Answer 1

查看def writePostsToSql(): con = sqlite3.connect("database.db") cur = con.cursor() cur.execute("CREATE TABLE IF NOT EXISTS posts (Id, PostTypeId, AcceptedAnswerId, Date, Time, Score, ViewCount, Body, OwnerUserId, Title, Tags, AnswerCount, FavoriteCount, PRIMARY KEY (Id), FOREIGN KEY (AcceptedAnswerId), FOREIGN KEY (OwnerUserId));") # use your column names here with open('Posts.csv', 'r') as fin: dr = csv.DictReader(fin) # comma is default delimiter to_db = [(i['Id'], i['PostTypeId'], i['AcceptedAnswerId'], i['Date'], i['Time'], i['Score'], i['ViewCount'], i['Body'], i['OwnerUserId'], i['Title'], i['Tags'], i['AnswerCount'], i['FavoriteCount']) for i in dr] cur.executemany("INSERT INTO posts (Id, PostTypeId, AcceptedAnswerId, Date, Time, Score, ViewCount, Body, OwnerUserId, Title, Tags, AnswerCount, FavoriteCount) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?);", to_db) con.commit() con.close()

config/packages/doctrine.yaml

这就是问题所在。每个.orm.yml都在那条路上搜索。

Answer 2

在app/config/packages/doctrine.yaml内

...
doctrine:

...

 orm:
        default_entity_manager: default
        auto_generate_proxy_classes: '%kernel.debug%'
        entity_managers:
            default:
                naming_strategy: doctrine.orm.naming_strategy.underscore
                connection: default


                #ADD THESE LINES AND CHANGE PATH IF NEEDED
                mappings:
                    App:
                        type: annotation
                        dir: '%kernel.project_dir%/src/Entity/'
                        prefix: 'App\Entity\'

运行php bin/console make:entity --regenerate

Answer 3

我有相同的错误，发现的解决方法是将repositoryClass添加到所有实体：

@ORM\Entity(repositoryClass="App\Repository\DefaultRepository")

最终代码如下：

/**
 * Key
 *
 * @ORM\Table(name="`key`")
 * @ORM\Entity(repositoryClass="App\Repository\DefaultRepository")
 */

希望对您有帮助

Answer 4

在您的实体类中，确保命名空间的格式如下：namespace App\Entity

Answer 5

在我的情况下，是因为我写了：

php bin/console make:entity --regenerate App\Entity\Course

代替（注意双反斜杠）

php bin/console make:entity --regenerate App\\Entity\\Course

Symfony 4使：实体--regenerate失败：在＆＃34; App＆＃34;中找不到实体。命名空间
