Creating And Saving Relational Data

Yii 2.0 General Discussions
1

I have a quick beginners question.

Is this the right way to deal with two models and one form in yii2 also? http://www.yiiframework.com/wiki/19/how-to-use-a-single-form-to-collect-data-for-two-or-more-models/

Or to be more precise, with two models that are related with hasMany.

?

I have tried this but I get error

Call to a member function formName() on a non-object

This is in my form


<?= $form->field($model->translations, 'title')->textInput(['maxlength' => 8]) ?>

And this is in my model


public function getTranslations()

{

    return $this->hasMany(Translation::className(), ['article_id' => 'id']);

}

Can someone help me? I’m stuck with this… :frowning:

I’m not sure about what are you trying to achieve. If you would like to select related model (by using Drop-down List) you might need something like this:


<?= $form->field($model, 'article_id')->dropDownList(ArrayHelper::map(Translation::find()->all(), 'id', 'name')) ?>

I have two tables, article and translation. They are related in Article model like this


public function getTranslations()

{

    return $this->hasMany(Translation::className(), ['article_id' => 'id']);

}

Now, when creating new article I have some fields that I insert into article table, but also have few fields that I need to insert into translation table.

I would like to do this with one form.

6

So you need to have 2 models,one for Translation and one for Articles.

Is that the right way?

In my controller I currently have


    public function actionKret()

    {

        $model = new Article;


        if ($model->load(Yii::$app->request->post()) && $model->save()) {

            return $this->redirect(['view', 'id' => $model->id]);

        } else {

            return $this->render('kret', [

                'model' => $model,

                //'translation' => $translation,

            ]);

        }

    }

And in my form




.....


<?= $form->field($model, 'upvote')->textInput(['maxlength' => 8]) ?>


<?= $form->field($model, 'translations[title]')->textInput(['maxlength' => 8])->label('Title') ?>


<?= $form->field($model, 'translations[slug]')->textInput(['maxlength' => 8])->label('Slug') ?>

....
8

Dont’ think so…maybe something more like this:




public function actionKret()

    {

        $modelArticle = new Article;

         $modelTranslation = new Translation;


        if ($model->load(Yii::$app->request->post()) && $model->save()) {

            return $this->redirect(['view', 'id' => $model->id]);

        } else {

            return $this->render('kret', [

                'modelArticle' => $model,

                'modelTranslation' => $translation,

            ]);

        }

    }

and then




.....


<?= $form->field($modelArticle, 'upvote')->textInput(['maxlength' => 8]) ?>


<?= $form->field($modelTranslation, 'title')->textInput(['maxlength' => 8])->label('Title') ?>


<?= $form->field($modelTranslation, 'slug')->textInput(['maxlength' => 8])->label('Slug') ?>

....

Then ofcourse you have to do 2 saves, maybe…




$modelArticle->save();

$modelTranslation->articileID = $modelArticle->id; // just a guess for the names

$modelTranslation->save();

Hm, okay.

I thought that in Yii2 this will be handled somehow automatically with


public function getTranslations()

{

    return $this->hasMany(Translation::className(), ['article_id' => 'id']);

}

OK, thanks :slight_smile:
