Question

在app / models / Model中这验证了

//simulating incorrect user input
//$model->status='some-string';

public function rules()
{
    return [
        ['status', 'in', 'range' => [0]], //asserts true (why?)
      //['status', 'in', 'range' => [0], 'strict' => true], //asserts false (correct)

    ];
}

编辑：我已更新此问题以反映新的见解。

Answer 1

请确保在模型类中定义常量

 class model extends activeRecord {
const STATUS = 0;
public function rules()
{
    return [
        [['status'], 'in', 'range' => [self::STATUS]],
    ];
}
}

试试这个对我有用.....

Answer 2

在验证时，

状态很可能为空，内部检查计算为：

// non-strict:
null == 0  // this is true

// strict:
null === 0 // this is false

同样适用于空字符串，请参阅related question
