yii 用AR插入，删除都可以，就是更新没有效果

public function updateToken()
{
        $result = $this->find()
            ->where(['token' => $this->lastToken])
            ->one();
        print_r($result);
        $result->mobile = 'cccccc';
        echo "<br><br><br>";
        print_r($result);   
        $result->save();
}

app\appClient\models\token Object ( [lastToken] => [did] => [Ver] => [_attributes:yii\db\BaseActiveRecord:private] => Array ( [user_id] => [mobile] => aaabbbbba [token] => d9d59a7ea590dc66cb930bbbe1759031 [password] => [lat] => [lng] => [time] => 0 [login] => 0 ) [_oldAttributes:yii\db\BaseActiveRecord:private] => Array ( [user_id] => [mobile] => aaabbbbba [token] => d9d59a7ea590dc66cb930bbbe1759031 [password] => [lat] => [lng] => [time] => 0 [login] => 0 ) [_related:yii\db\BaseActiveRecord:private] => Array ( ) [_errors:yii\base\Model:private] => [_validators:yii\base\Model:private] => [_scenario:yii\base\Model:private] => default [_events:yii\base\Component:private] => Array ( ) [_behaviors:yii\base\Component:private] => Array ( ) )


app\appClient\models\token Object ( [lastToken] => [did] => [Ver] => [_attributes:yii\db\BaseActiveRecord:private] => Array ( [user_id] => [mobile] => cccccc [token] => d9d59a7ea590dc66cb930bbbe1759031 [password] => [lat] => [lng] => [time] => 0 [login] => 0 ) [_oldAttributes:yii\db\BaseActiveRecord:private] => Array ( [user_id] => [mobile] => aaabbbbba [token] => d9d59a7ea590dc66cb930bbbe1759031 [password] => [lat] => [lng] => [time] => 0 [login] => 0 ) [_related:yii\db\BaseActiveRecord:private] => Array ( ) [_errors:yii\base\Model:private] => [_validators:yii\base\Model:private] => [_scenario:yii\base\Model:private] => default [_events:yii\base\Component:private] => Array ( ) [_behaviors:yii\base\Component:private] => Array ( ) )

这是2次打印的输出，也就是找到数据了，但是更新后没有效果，把update 改成 delete 确实能删除

this->find有你这样写的

帮你把代码修改如下

public function updateToken()
{
        $result = $this->findOne(['token' => $this->lastToken]);
        print_r($result);
        $result->mobile = 'cccccc';
        echo "<br><br><br>";
        print_r($result);   
        $result->save();
}

find()查出来的是对象数组,也就是说类似如下结构

[
  [...],
  [...],
]

虽然你使用了one(),但是你的$result对应的仍是find(),但是find()是如下方式构建的

    /**
     * @inheritdoc
     * @return ActiveQuery the newly created [[ActiveQuery]] instance.
     */
    public static function find()
    {
        return Yii::createObject(ActiveQuery::className(), [get_called_class()]);
    }

它返回的是一个ActiveQuery对象,而findOne()是如下构建的

    /**
     * @inheritdoc
     * @return static|null ActiveRecord instance matching the condition, or `null` if nothing matches.
     */
    public static function findOne($condition)
    {
        return static::findByCondition($condition)->one();
    }

它返回的是一个ActiveRecord对象,只有ActiveRecord对象才能进行save()
