Question

我正在设置一个Symfony2应用程序，并尝试使用Doctrine迁移。在这个特定的例子中，我正在尝试为我刚刚创建的实体，客户端添加一个新表，客户端。此表目前在数据库中不存在任何形式。

当我运行php app / console doctrine：migrations：diff时，我收到以下错误：

[Doctrine\DBAL\Schema\SchemaException]                       
There is no column with name 'brand_id' on table 'clients'

当然没有该名称的列，该表尚不存在！

Doctrine是否应该认识到没有表并创建它？作为参考，这是我的实体：

<?php

namespace RandomBundle\Entity;

use Doctrine\ORM\Mapping as ORM;

/**

Answer 1

我能看到的唯一一点是索引声明

 * @ORM\Table(name="clients", indexes={@ORM\Index(name="brand_id", columns={"brand_id"})})

我不知道它是否在创建表格之前尝试创建索引。
尝试删除它以查看问题是否仍然存在

Doctrine \ DBAL \ Schema \ SchemaException - 表'clients'上没有名为'brand_id'的列
