Yii 行为不会保存数据

Question

我正在尝试在第三个 table 'Relations' 中保存关系。这是代码：

控制器保存操作：

$relations = $_POST['VideoCaptions']['countries'];
                $model->attachBehavior('ManyToManyRelationBehavior', array(
                    'class' => 'ManyToManyRelationBehavior',
                    'modelNameRelation' => 'Relations',
                    'firstField' =>  'video_captions',
                    'secondField' => 'video_countries',
                    'relationList' => $relations,
                ));

ManyToManyRelationBehavior class afterSave 操作：


    if (is_array($this->relationList)){
                $model_ = $this->modelNameRelation;
                $model_::model()->deleteAll("<code>first_field = :firstField AND first_field_value = :firstFieldValue AND second_field = :secondField", array(
                    ":firstField" => $this->firstField,
                    ":firstFieldValue" => $this->owner->id,
                    ":secondField" => $this->secondField
                ));
                foreach ($this->relationList as $value){
                    $model_ = new $this->modelNameRelation;
                    $model_->first_field = $this->firstField;
                    $model_->first_field_value = $this->owner->id;
                    $model_->second_field = $this->secondField;
                    $model_->second_field_value = intval($value);
                    if (!$model_->save()) return false;
                }
            }
            return true;

var_dump($model_) returns 该模型存在，但 $model->save() 不保存任何数据 table 'Relations'。我不明白为什么。有人可以帮忙吗？

Answer 1

您为此 "modelNameRelation" 设置了哪些验证？您应该尝试 insert() 方法而不是 save() 并检查它是否有效？先保存验证再调用insert()或update()方法

Answer 2

已解决：

    foreach ($this->relationList as $value){
        $model = new $this->modelNameRelation;
        $model->first_field = $this->firstField;
        $model->first_field_value = $this->owner->id;
        $model->second_field = $this->secondField;
        $model->second_field_value = intval($value);
        Yii::app()->db->createCommand()->insert($model->tableName(), $model->attributes);
    }
