Sonata Admin Bundle - RouteCompiler 错误，因为占位符长于 32 个字符
Sonata Admin Bundle - RouteCompiler error because of placeholder longer than 32 char
我刚刚使用 composer 更新了我的包，然后 Symfony 抛出了一个错误。在更新之前，我的应用程序 运行 没问题。
错误：
Variable name "childChildChildChildChildChildChildId" cannot be longer than 32 characters in route pattern "/admin/project/rest/member/{id}/shelves_member/{childId}/contributor/{childChildId}/series/{childChildChildId}/shelves_series/{childChildChildChildId}/post/{childChildChildChildChildId}/tag/{childChildChildChildChildChildId}/event/{childChildChildChildChildChildChildId}/edit". Please use a shorter name.
解释：
管理员似乎在 admin.yml 中嵌套得很深，这使得动态生成的 'childchild...' 占位符超过 32 个字符，这又会引发错误，因为 [=41] =] 来自 Symfony 的占位符限制由常量 VARIABLE_MAXIMUM_LENGTH 定义为 32 个字符。
我没有在奏鸣曲文档中找到任何关于自定义占位符或为其设置最大长度的内容。
现在，我发现让应用程序在更新后运行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。

感谢您的帮助！
我 运行 遇到了同样的问题，在阅读了您添加到 github 的问题后，我解决了这个问题如下：
首先，我创建了自己的 AbstractAdmin 来扩展奏鸣曲的
我所有的奏鸣曲管理员 类 然后扩展我的抽象管理员。
在我的 AbstractAdmin 中，我覆盖了 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 - 只是为了更多。
无法绕过 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。
