Symfony2中的KNP菜单bundle中的覆盖选项

Question

来自默认的knp菜单捆绑模板：

{%- elseif matcher.isAncestor(item, options.matchingDepth) %}
    {%- set classes = classes|merge([options.ancestorClass]) %}

options.ancestorClass等于" Current_ancestor"。有没有办法覆盖这一点？我不想复制涵盖50行代码的Wohle块项目代码，我只需要更改一个值。

要在所有应用程序中应用默认选项，您可以将knp_menu.renderer.twig.options参数设置为这样：

// app/config/services.yml
parameters:
    knp_menu.renderer.twig.options:
        currentClass: active

KnpMenuRendererTwigRenderer的默认选项是：

    $this->defaultOptions = array_merge(array(
        'depth' => null,
        'matchingDepth' => null,
        'currentAsLink' => true,
        'currentClass' => 'current',
        'ancestorClass' => 'current_ancestor',
        'firstClass' => 'first',
        'lastClass' => 'last',
        'template' => $template,
        'compressed' => false,
        'allow_safe_labels' => false,
        'clear_matcher' => true,
        'leaf_class' => null,
        'branch_class' => null,
    ), $defaultOptions);

尝试

{{ knp_menu_render('AcmeDemoBundle:Builder:mainMenu', {'ancestorClass': 'your-class'}) }}
