我有一个预算表，在 select 字段中列出了来自客户实体的数据。总之，预算和客户是相互关联的。预算有 client_id 列，假设通过从所选客户获取 id 值来存储它。
<form action="{{ path('panel_add_budget') }}" method="POST">
<strong>Cliente</strong>
<div class="form-group">

提交表单时，抛出异常：

这对我来说没有任何意义。我不知道该怎么办。其他人的解决方案根本没有帮助我。如果您需要更多代码，请询问我，我将对其进行编辑。谢谢。
我建议您在实体中使用注释，并开始使用表单生成器。还要向客户端实体添加一个 __toString() 方法！
您的实体：
namespace AppBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Validator\Constraints as Assert;
use Doctrine\Common\Collections\ArrayCollection;
/**
* Client
*
* @ORM\Table()
* @ORM\Entity
*/
class Client
{
/**
* @var integer
*
* @ORM\Column(name="id", type="integer")
* @ORM\Id
* @ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* @var string
*
* @ORM\Column(name="name", type="string", length=64)
*/
private $name;
// YOUR OTHER CLIENT FIELDS
/**
* @ORM\OneToMany(targetEntity="Budget", mappedBy="client")
**/
private $budgets;
public function __construct() {
$this->budgets = new ArrayCollection();
}
/* this function is required to present the entity as a string */
public function __toString() {
return $this->name;
}
}
第二个：
namespace AppBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Validator\Constraints as Assert;
/**
* Budget
*
* @ORM\Table()
* @ORM\Entity
*/
class Budget
{
/**
* @var integer
*
* @ORM\Column(name="id", type="integer")
* @ORM\Id
* @ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
// YOUR BUDGET FIELDS
/**
* @ORM\ManyToOne(targetEntity="Client", inversedBy="budgets")
* @ORM\JoinColumn(name="client_id", referencedColumnName="id")
**/
private $client;
}
然后在项目主目录的控制台中输入以下命令：
（也许你必须在每个命令前输入单词php）
app/console doctrine:generate:entities AppBundle
app/console doctrine:schema:update --force
app/console doctrine:generate:crud AppBundle:Client
( type YES by the question Do you want to generate the "write" actions [no]?)
app/console doctrine:generate:crud AppBundle:Budget
( type YES by the question Do you want to generate the "write" actions [no]?)
并查看新路线：
app/console router:debug
如您所见，您可以浏览到
web/app_dev.php/client/ 到
web/app_dev.php/budget/来看看！
然后在你的编辑器中打开../src/AppBundle/Form/BudgetType.php你会发现这条规则：
$builder
->add('client')
;
这是将客户端 属性 添加到表单的地方。 Symfony 自动将此表单字段设置为 entity formtype。你也可以这样写：
$builder
->add('client', 'entity', array(
'class' => 'AppBundle:Client',
'empty_value' => '',
))
;
现在您可以在预算表中选择您的客户。
您可能已经注意到，这些命令还为您添加了一个 ClientController 和一个 BudgetController。
有关 formtypes 的更多信息，请参阅文档。
我有一个预算表，在 select 字段中列出了来自客户实体的数据。总之，预算和客户是相互关联的。预算有 client_id 列，假设通过从所选客户获取 id 值来存储它。

这对我来说没有任何意义。我不知道该怎么办。其他人的解决方案根本没有帮助我。如果您需要更多代码，请询问我，我将对其进行编辑。谢谢。
我建议您在实体中使用注释，并开始使用表单生成器。还要向客户端实体添加一个 __toString() 方法！
您的实体：
namespace AppBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Validator\Constraints as Assert;
use Doctrine\Common\Collections\ArrayCollection;
/**
* Client
*
* @ORM\Table()
* @ORM\Entity
*/
class Client
{
/**
* @var integer
*
* @ORM\Column(name="id", type="integer")
* @ORM\Id
* @ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* @var string
*
* @ORM\Column(name="name", type="string", length=64)
*/
private $name;
// YOUR OTHER CLIENT FIELDS
/**
* @ORM\OneToMany(targetEntity="Budget", mappedBy="client")
**/
private $budgets;
public function __construct() {
$this->budgets = new ArrayCollection();
}
/* this function is required to present the entity as a string */
public function __toString() {
return $this->name;
}
}
第二个：
namespace AppBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Validator\Constraints as Assert;
/**
* Budget
*
* @ORM\Table()
* @ORM\Entity
*/
class Budget
{
/**
* @var integer
*
* @ORM\Column(name="id", type="integer")
* @ORM\Id
* @ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
// YOUR BUDGET FIELDS
/**
* @ORM\ManyToOne(targetEntity="Client", inversedBy="budgets")
* @ORM\JoinColumn(name="client_id", referencedColumnName="id")
**/
private $client;
}
然后在项目主目录的控制台中输入以下命令： （也许你必须在每个命令前输入单词php）
app/console doctrine:generate:entities AppBundle
app/console doctrine:schema:update --force
app/console doctrine:generate:crud AppBundle:Client
( type YES by the question Do you want to generate the "write" actions [no]?)
app/console doctrine:generate:crud AppBundle:Budget
( type YES by the question Do you want to generate the "write" actions [no]?)
并查看新路线：
app/console router:debug
如您所见，您可以浏览到
web/app_dev.php/client/ 到
web/app_dev.php/budget/来看看！
然后在你的编辑器中打开../src/AppBundle/Form/BudgetType.php你会发现这条规则：
$builder
->add('client')
;
这是将客户端 属性 添加到表单的地方。 Symfony 自动将此表单字段设置为 entity formtype。你也可以这样写：
$builder
->add('client', 'entity', array(
'class' => 'AppBundle:Client',
'empty_value' => '',
))
;
现在您可以在预算表中选择您的客户。
您可能已经注意到，这些命令还为您添加了一个 ClientController 和一个 BudgetController。 有关 formtypes 的更多信息，请参阅文档。
