Question

似乎我在这里遗漏了一些东西而且我一直收到以下信息：

##在呈现模板期间抛出异常（＆＃34;缺少一些必需参数（＆＃34; fooId＆＃34;）以生成路由的网址＆＃34; foo_edit＆＃34; 。＆＃34;）在AdminFooBundle中：默认：base.html.twig在第1行。##

这是Controller的行动：

/**
 * @Route("/{fooId}/edit", name="foo_edit", requirements={"fooId" = "\d+"})
 * @param $fooId
 *
 * @return View
 */
public function editFooFormAction($fooId)
{
    $foo = $this->getFooRepository()->findOneBy(['fooId' => $fooId]);

    return $this->render(
        "AdminFooBundle:Competition:show_foo.html.twig",
        ['foo' => $foo]
    );
}

这是我的枝条文件：

{% extends 'FooAdminToolBundle:Default:base.html.twig' %}

{% block inner_main %}
{{ parent() }}

<form data-spy="scroll" data-target="#affix-nav" action="{{ path('foo_create') }}" method="post">
    <button type="submit" style="position: absolute; left:-10000px;"></button>
    {% include 'FooAdminBundle:Foo:foo_data.html.twig'%}
    <button type="submit" class="btn btn-default">Add new foo</button>
</form>
{% endblock %}

我的猜测是问题在于扩展Default：base.html.twig，但我现在看不到：

    {% set currentPath = path(app.request.attributes.get('_route')) %}
<!DOCTYPE html>
<html lang="en">
<head>
        <title>    {% block title %}Admin Tool{% endblock %}</title>

    {% block stylesheets %}
        <link rel="stylesheet" href="//maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap.min.css">
        <link rel="stylesheet" href="//maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap-theme.min.css">
    {% endblock %}

    {% block headcss %}
    {% endblock %}

    {% block headjavascripts %}
    {% endblock %}

    <link rel="icon" type="image/x-icon" href="{{ asset('favicon.ico') }}" />
</head>
<body data-spy="scroll" data-target="#affix-nav">

    {% include 'FooAdminBundle:Default:navbar.html.twig' %}

    <div class="container">

        {% block main %}{% endblock %}

        <div class="row">
            <div class="col-sm-9">
                {% block inner_main %}{% endblock %}
            </div>
            <div class="col-sm-3">
                <div id="options" data-spy="affix"></div>
            </div>
        </div>

    </div> <!-- /main -->

检查参数$ fooId是否有效。在你的路线是强制性的，也许因为缺少，所以会引发错误。
