Question

我正在使用Symfony 2.8和Doctrine，我将security.yml配置为指向实现 UserInterface 的用户类。我的ORM架构在YAML中。

问题： - 在数据库中，用户还指定了“email”字段，LOGGED USER的Symfony没有填写该字段，“password”字段也是空的。

当我public static TreeNode convert_loop(char[] expr) { if (expr == null || expr.length < 1) { return null; } if (expr.length == 1) { return new TreeNode(expr[0]); } if ((expr.length - 1) % 4 != 0) { throw new InputMismatchException("wrong expression"); } int start = 0, end = expr.length - 1; TreeNode<Character> root = new TreeNode<>(expr[start]); root.right = new TreeNode<>(expr[end]); start += 2; end -= 2; TreeNode<Character> cur = root; while (start != end) { TreeNode<Character> node = new TreeNode<>(expr[start]); node.right = new TreeNode<>(expr[end]); cur.left = node; cur = node; start += 2; end -= 2; } cur.left = new TreeNode(expr[start]);// care return root; }时那么实体管理器正确地获取实体。但是当实体正在来自会话时，则它是不正确的。

问题还在于，当我尝试使用存储库上的find（）从数据库中获取新的实体时，当我不使用$this->get('doctrine.orm.entity_manager')->clear(User::class);

时，将获取会话中的错误元素

问题： - 如何告诉Symfony / Doctrine以这样的方式构建我的实体，它将填满所有字段，以便它可以保持不变？

$em->clear(User::class)

和ORM配置：

您实现了UserInterface :: eraseCredentials（）方法，其方式是取消设置电子邮件和密码：

public function eraseCredentials()
{
    $this->password = null;
    $this->email    = null;
}

Symfony将在序列化对象之前调用此方法，以将其保存在会话中。

UserInterface :: eraseCredentials（）用于从用户对象中删除敏感数据，因此它不会以例如会话文件结束，但实际上并不需要像您一样删除电子邮件。一个更好的例子是，如果你在这个对象的某个地方存储用户密码的纯文本版本，这是你永远不想在会话文件中结束的东西。

Symfony - 已登录的用户未填写所有字段
