在gridview中按FK搜索筛选用户

分类：编程问答

如何解决在gridview中按FK搜索筛选用户

我的用户表包含：PK-ID，用户名，密码。 我有三张桌子（笔记本电脑，显示器，电话）-ID-FK，系列，型号 我有userequipmentmapping表，其中包含：id-PK，user_id-FK（来自用户表的ID），laptop_id-FK（来自笔记本电脑表的ID），phone_id-FK（来自电话表的ID），display_id（来自dislpay表的ID），start_date，结束日期。

我想通过UserEquipmentMapping在gridview中按用户搜索，但是考虑到用户名是通过外键从users表传递的，所以我不知道应该在哪里实现搜索模型。 如有任何建议，我们将不胜感激。预先谢谢您！

<div class="user-equipment-mapping-index">

    <h1><?= Html::encode($this->title) ?></h1>

    <p>
        <?= Html::a('Create User Equipment Mapping',['create'],['class' => 'btn btn-success']) ?>
    </p>

    <?php // echo $this->render('_search',['model' => $searchModel]); ?>

    <?= GridView::widget([
        'dataProvider' => $dataProvider,'filterModel' => $searchModel,'formatter' => [
            'class' => 'yii\i18n\Formatter','nullDisplay' => '-','columns' => [
            ['class' => 'yii\grid\SerialColumn'],#'id','user.username',#'laptop.laptop_model','laptop.laptop_series',#'laptop_id',#'phone.phone_model','phone.phone_series',#'phone_id',#'display.display_model','display.display_series',#'display_id','start_date','stop_date',['class' => 'yii\grid\ActionColumn'],]); ?>


</div>

解决方法

在索引视图_search视图中取消注释。来自UserequipmentmappingSearch模型的所有字段。您可以将输入字段替换为用户，笔记本电脑等的选择字段。搜索模型将做另一件事，所有操作都在填充数据提供者的搜索功能中
