Symfony2 - 从数据库中提取数据并显示在表单中

Question

我想在我的表单上显示数据，但我不能这样做。

这是我在 userbundle 下的 profile.php：

 <?php

namespace project\UserBundle\Entity;

use Doctrine\ORM\Mapping as ORM;

/**
 * Profile
 *
 * @ORM\Table(name="project_profiles")

    }
}

我已经在 Resources/Profile/show.html 下声明了我的实体，并且一切正常： 例如我的地址：

<th>Address2</th>
<td>{{ entity.address2 }}</td>

我的问题是我有另一个名为 ShowBundle 的包，我想在该包上显示这些实体。例如，当我在该捆绑包上调用 {{ entity.address2 }} 以显示我的地址时，它向我显示：（变量“实体”不存在）

我如何在另一个包中的树枝表单上显示这些配置文件实体，在我的例子中是 ShowBundle？

非常感谢

当然你可以使用{{ app.user.variablename }}，它是一个全局变量。但是对于其他变量，视图只能显示控制器发送给它的数据。这就是 MVC（模型-视图-控制器）架构。

变量entity 仅在您的控制器将其发送到视图时才存在于 Twig 视图中。这就是 return array( 'entities' => $entities ); 在 ProfileController.php 上所做的，这就是为什么你可以在 Resources/Profile/show.html 中使用它。

如果您想在另一个包中显示一个实体，只需将其从数据库中拉出并将其发送到视图，就像您在 ProfileController.php 中所做的那样。如果您自己编写发布的代码，那应该是一件容易的事。

如果你不明白你贴的代码，我建议你学习使用 Symfony。您可以阅读the Book，这是非常好的分步文档。

提示：

将此代码复制到您的其他捆绑控制器中（以Action() 结尾的方法）：

$em = $this->getDoctrine()->getManager(); //get the database manager

$profiles = $em->getRepository('projectUserBundle:Profile')->findAll(); // get the profiles

return array(
        'profiles' => $profiles,
    ); // send data to the view

您将通过模板中的{{ profiles }} 访问您的个人资料。
