Question

我试图在第三个表格＆＃39;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类afterSave操作：


    if (is_array($this->relationList)){
                $model_ = $this->modelNameRelation;
                $model_::model()->deleteAll("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_）返回该模型存在，但$ model-＆gt; save（）不保存表格中的任何数据＆＃39;关系＆＃39;。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？您应该尝试使用insert（）方法而不是save（）并检查它是否可以工作？保存第一个验证然后调用insert（）或update（）方法。

Answer 2

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);
    }

Yii行为不会保存数据
