yii – 多个相关模型单控制器

我有两个型号“Recipes”和“RecipeSteps”

这是我的食谱关系

public function relations()
    {
        // NOTE: you may need to adjust the relation name and the related
        // class name for the relations automatically generated below.
        return array(
        'recipeSteps' => array(self::HAS_ONE,'RecipeSteps','recipe_id'),);
    }

我已经可以使用相关模型创建和更新问题,在搜索中我可以在结果中看到相关模型“RecipeSteps”,因为我将它添加到我的Gridview中,如下所示：

<?php $this->widget('zii.widgets.grid.CGridView',array(
    'id'=>'recipes-grid','dataProvider'=>$model->search(),'filter'=>$model,'columns'=>array(
        //'recipe_id','recipe_name','recipe_description','recipeSteps.instructions',array(
            'class'=>'CButtonColumn',),)); ?>

但是,我需要弄清楚如何在“指令”字段上方的搜索栏中添加,以便也可以搜索字段.

我需要弄清楚如何在表单中添加“说明”.

<div class="wide form">

<?php $form=$this->beginWidget('CActiveForm',array(
    'action'=>Yii::app()->createUrl($this->route),'method'=>'get',)); ?>

    <div class="row">
        <?php echo $form->label($model,'recipe_name'); ?>
        <?php echo $form->textField($model,array('size'=>11,'maxlength'=>11)); ?>
    </div>

    <div class="row">
        <?php echo $form->label($model,'recipe_description'); ?>
        <?php echo $form->textArea($model,array('rows'=>6,'cols'=>50)); ?>
    </div>

    <div class="row buttons">
        <?php echo CHtml::submitButton('Search'); ?>
    </div>

<?php $this->endWidget(); ?>

</div><!-- search-form -->

食谱中的配方搜索功能

public function search()
    {
        // Warning: Please modify the following code to remove attributes that
        // should not be searched.

        $criteria=new CDbCriteria;

        //$criteria->compare('recipe_id',$this->recipe_id,true);
        $criteria->compare('recipe_name',$this->recipe_name,true);
        $criteria->compare('recipe_description',$this->recipe_description,true);

        return new CActiveDataProvider($this,array(
            'criteria'=>$criteria,));

以及RecipesController中的Index和Admin

/**
 * Lists all models.
 */
public function actionIndex()
{
    $dataProvider=new CActiveDataProvider('Recipes');
    $this->render('index',array(
        'dataProvider'=>$dataProvider,));
}

/**
 * Manages all models.
 */
public function actionAdmin()
{
    $model=new Recipes('search');
    $model->unsetAttributes();  // clear any default values
    if(isset($_GET['Recipes']))
        $model->attributes=$_GET['Recipes'];

    $this->render('admin',array(
        'model'=>$model,));
}

我知道这应该很简单,但我似乎无法弄清楚如何绕过它我已经阅读了我能找到的每一份文件.
