Yii2从整数转换为日期时间以显示并保存到带有整数的数据库中

Question

我有一个表for_date在数据库中按类型整数保存列.为了for_date使用DateTime格式显示,我使用ActiveForm代码:

<?= $form->field($model, 'for_date')->textInput([
    'class' => 'form-control datepicker',
    'value' => $model->for_date ? date(Yii::$app->params['dateFormat'], $model->for_date) : date(Yii::$app->params['dateFormat'], time()),
    'placeholder' => 'Time'])
    ->label('Attendance Date') ?>

但是,当我创造和保存时,Yii通知 This field must be integer

在模型文件中,我有两个函数在验证之前进行转换,但它仍然是错误的.

public function beforeValidate(){
    if(!is_int($this->for_date)){
        $this->for_date = strtotime($this->for_date);
        $this->for_date = date('d/M/Y', $this->for_date);
    }
    return parent::beforeValidate();
}

public function afterFind(){
    $this->for_date = \Yii::t('app', Yii::$app->formatter->asDate($this->for_date));
    $this->for_date = date('d/M/Y', $this->for_date);
    return parent::afterFind();
}

如何使用整数保存到数据库中？

Answer 1

我找到了解决方案。在模型搜索（我的情况是AttendanceSearch.php）中，查找规则功能并for_date从线必须移动integer到线以下safe

我的代码：

public function rules()
    {
        return [
            [['id', 'user_id', 'project_id', 'commit_time', 'workload_type'], 'integer'],
            [['comment', 'for_date'], 'safe'],
        ];
    }
