Sonata Admin Bundle - RouteCompiler 错误，因为占位符超过 32 个字符

【中文标题】Sonata Admin Bundle - RouteCompiler 错误，因为占位符超过 32 个字符

【英文标题】：Sonata Admin Bundle - RouteCompiler error because of placeholder longer than 32 char

【发布时间】：2018-09-20 03:16:54

【问题描述】：

我刚刚使用 composer 更新了我的包，从那时起 Symfony 抛出了一个错误。在更新之前，我的应用程序运行良好。

错误：

在路由模式“/admin/project/rest/member/id/shelves_member/childId/contributor/childChildId/series/childChildChildId/shelves_series”中，变量名“childChildChildChildChildChildChildId”不能超过 32 个字符/childChildChildChildId/post/childChildChildChildChildId/tag/childChildChildChildChildChildChildId/event/childChildChildChildChildChildChildId/edit”。请使用较短的名称。

解释：

看起来管理员在 admin.yml 中嵌套得非常深，这使得动态生成的 'childchild...' 占位符超过 32 个字符，这反过来又会引发错误，因为 Symfony 的 RoutingCompiler.php 有由常量 VARIABLE_MAXIMUM_LENGTH 定义的占位符限制为 32 个字符。

我在奏鸣曲文档中没有找到任何关于自定义占位符或为它们设置最大长度的内容。

目前，我发现在更新后让应用程序正常工作的唯一方法是将此常量更改为 64 个字符，但我很确定这不是一个好主意，因为它可能会破坏其他地方。

（编辑：添加堆栈跟踪）

感谢您的帮助！

【问题讨论】：

或许您应该将此报告为错误。

你能给我们堆栈跟踪，是 Symfony 还是 Sonata 问题？

占位符的 32 个字符限制在 Symfony 中定义。问题出在 Sonata 中，因为如果您的子管理员嵌套得足够深，它会动态创建比限制更长的占位符。我已经添加了堆栈跟踪

@OlivierMaurel 我们唯一能做的就是缩短名称，您能在 Admin Bundle 上打开一个问题吗？

@kunicmarko20 感谢您的帮助！我已经在 github 上提交了这个问题。 github.com/sonata-project/SonataAdminBundle/issues/5072

【参考方案1】：

我遇到了同样的问题，在阅读了你添加到 github 的问题后，我解决了这个问题：

首先，我创建了自己的 AbstractAdmin 来扩展 Sonata 的。

我所有的 Sonata 管理类然后扩展我的抽象管理。

在我的 AbstractAdmin 中，我重写了 getIdParameter() 方法以强制 Sonata 使用较短的占位符 - 'c' 而不是 'child'：

<?php
namespace App\Admin;

use Sonata\AdminBundle\Admin\AbstractAdmin as SonataAbstractAdmin;

abstract class AbstractAdmin extends SonataAbstractAdmin

    public function getIdParameter()
    
        $parameter = 'id';

        for ($i = 0; $i < $this->getChildDepth(); ++$i) 
            $parameter = sprintf('c%s', ucfirst($parameter));
        

        return $parameter;
    

请注意，这不允许无限嵌套 - 只是更多。

没有办法绕过 Symfony 规定的每个占位符 32 个字符的总体限制。

正如您自己指出的那样，它是一个可以被覆盖的常量，但这可能不是一个好主意。
