Question

我收到错误＆＃34;不能使用Symfony \ Component \ Form \ FormRenderer类型的对象作为数组＆＃34;当我尝试使用Symfony在我的Sonata Admin Bundle中创建一个新实体时。我之前没有遇到过这个问题，而且我在管理文件中没有任何改变。

环境

Php 7.0, Mysql

这是我的管理文件的样子：

    }

    }


    public function prePersist($team)

Answer 1

将此设置添加到app / config / services.yml

twig.form.renderer2:
    class: Symfony\Bridge\Twig\Form\TwigRenderer
    tags:
        - { name: twig.runtime }
    arguments: [ '@twig.form.engine', '@security.csrf.token_manager']
