How to create database table from entity in symfony 2.6
提问by Umair Malik
what i've done so far is -> i have created a bundle and entity class in it and created a database table named "news" from that entity class using following command
到目前为止我所做的是 -> 我在其中创建了一个包和实体类，并使用以下命令从该实体类创建了一个名为“news”的数据库表
php app/console doctrine:schema:update --force
php 应用程序/控制台学说：模式：更新 --force
everything went well.
一切顺利。
now i created a new bundle and an other entity class in it from which i want to create an other table in database named "user" but gives an error that "The table with name 'symfony.news' already exists' ".
现在我在其中创建了一个新包和一个其他实体类，我想从中创建一个名为“user”的数据库中的另一个表，但给出了一个错误“名称为‘symfony.news’的表已经存在”。
class user {
private $id;
private $userEmail;
public function getId() {
return $this->id;
}
public function setUserEmail($userEmail) {
$this->userEmail = $userEmail;
return $this;
}
}

Your entity doesn't contain annotations, and doctrine have no idea what to do with this entity. But if you add to you entity something like:
您的实体不包含注释，并且学说不知道如何处理该实体。但是，如果您向实体添加以下内容：
<?php
namespace AppBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* @ORM\Entity
* @ORM\Table(name="user")
*/
class User
{
/**
* @ORM\Column(type="integer")
* @ORM\Id
* @ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* @ORM\Column(type="string", length=60, unique=true)
*/
private $email;
public function getId()
{
return $this->id;
}
public function setUserEmail($userEmail)
{
$this->userEmail = $userEmail;
return $this;
}
}
OR
或者
if you add file: User.orm.xmllike:
如果添加文件：User.orm.xml如：
<?xml version="1.0" encoding="utf-8"?>
<doctrine-mapping xmlns="http://doctrine-project.org/schemas/orm/doctrine-mapping" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://doctrine-project.org/schemas/orm/doctrine-mapping http://doctrine-project.org/schemas/orm/doctrine-mapping.xsd">
<entity name="AppBundle\Entity\User" table="user">
<unique-constraints>
<unique-constraint name="UNIQ_797E6294E7927C74" columns="email"/>
</unique-constraints>
<id name="id" type="integer" column="id">
<generator strategy="IDENTITY"/>
</id>
<field name="email" type="string" column="email" length="60" nullable="false"/>
</entity>
</doctrine-mapping>
to your Resources/config/doctrine/directory,
you'll be able to run command:
到您的Resources/config/doctrine/目录，您将能够运行命令：
php app/console doctrine:schema:update --force
and as result you'll receive:
结果你会收到：
Updating database schema...
Database schema updated successfully! "1" queries were executed
Truly believe that it will solve your problem...
相信它会解决你的问题...

Why don't you use doctrine command?
你为什么不使用学说命令？
php app/console doctrine:generate:entity
