对 Laravel "sometimes" 验证工作感到困惑

Question

我真的很困惑为什么会这样？我已经成功添加了一条记录，然后当我尝试更新记录时它说即使我已经通过了该字段也是必需的。然后当我尝试在验证中添加 "sometimes" 时。现在，它起作用了。为什么？请赐教。谢谢！

my Test Model

This was the result when I tried to remove "sometimes"

Answer 1

根据文档 sometimes 用于：

Validating When Present In some situations, you may wish to run validation checks against a field only if that field is present in the input array. To quickly accomplish this, add the sometimes rule to your rule list:
$v = Validator::make($data, [
    'email' => 'sometimes|required|email', ]);

因此，由于请求不包含预期的字段，因此验证成功

Answer 2

添加 sometimes 有效地禁用了 required 规则，并允许客户端简单地不将该字段传递到输入中。

在您的情况下，验证器可能没有从输入中接收到正确的数据。因为如果是这样，required 规则将正确执行。

请post验证器的代码以便能够调试问题。

Answer 3

sometimes 是您有时包含该字段的时候。

让我们看一个创建用户时的验证示例：-

$validation = [
 "name" => "required|string|",
 "email" => "required|email",
 "hobbies" => "sometimes|array"
];

有效负载示例

{
 name: "Bob",
 email: "bob@gmail.com"
}
// this will pass

{
 name: "Bob",
 email: "bob@gmail.com",
 hobbies: ["fishing", "swimming"]
}
// this would also pass

{
 name: "Bob",
 email: "bob@gmail.com",
 hobbies: "swimming"
}
// this would fail since it doesn't match "array" validation
