symfony2 crud用户实体，角色分配

时间：2015-02-13 09:32:50

标签： symfony doctrine-orm

我在使用crud和用户实体时遇到麻烦（使用sf2玩一点）。我一直在关注symfony cookbook，以便在数据库和角色中保存用户，并且我已经为用户实体和角色实体生成了crud。在用户实体上我有用于分配角色的字段但它在选择选项中显示了角色的ID而不是名称，我不确定如何修改字段以显示角色名称。你能帮我吗 ？

在__toString()实体类中实施Role方法。

public function __toString()
{
    return $this->name;
}

您还可以将'property' => 'name'选项传递给roles字段
