symfony - SonataAdminBundle 中不存在函数 "is_granted"

Question

安装后Symfony2 cmf ，当我尝试查看管理/仪表板时，出现以下错误:

The function "is_granted" does not exist in SonataAdminBundle :: standard_layout.html.twig at line 95

我也为此苦苦挣扎了很多时间。修复方法如下:

将 SecurityBundle 添加到 app/AppKernel.php

public function registerBundles()
{
    $bundles = array(
        // ...

        // support for the admin
        new Symfony\Bundle\SecurityBundle\SecurityBundle(),
    );
    // ...
}

在 app/config 文件夹中创建一个 security.yml，例如与此演示内容:

security:
    encoders:
        Symfony\Component\Security\Core\User\User: plaintext

    role_hierarchy:
        ROLE_ADMIN:       ROLE_USER
        ROLE_SUPER_ADMIN: [ROLE_USER, ROLE_ADMIN, ROLE_ALLOWED_TO_SWITCH]

    providers:
        in_memory:
            memory:
                users:
                    user:  { password: userpass, roles: [ 'ROLE_USER' ] }
                    admin: { password: adminpass, roles: [ 'ROLE_ADMIN' ] }
    firewalls:
        dev:
            pattern:  ^/(_(profiler|wdt)|css|images|js)/
            security: false
        main:
            pattern: ^/
            anonymous: ~
            http_basic:

                realm: "Secured Demo Area"
    access_control:
        #- { path: ^/login, roles: IS_AUTHENTICATED_ANONYMOUSLY, requires_channel: https }
        #- { path: ^/_internal/secure, roles: IS_AUTHENTICATED_ANONYMOUSLY, ip: 127.0.0.1 }

并将其加载到您的app/config/config.yml:

imports:
    - { resource: security.yml }

这对我有用。
