Good afternoon.

I've the following:

*** 3 tables ***
- Authors (IdAuthor, AuthorName)
- Books (IdBook, BookName)
- Authors_Books (IdAuthor, IdBook)

*** 2 models ***
- Authors
- Books

A books can have multiple authors.

In my Books view, I've a form with a dropdownlist for Authors.AuthorName and a textarea for Books.BookName.

I want:

1- Put 2 buttons (Add and Remove) and a CListView in the Books view's form. When I click on Add button, the Author selected in dropdownlist will be added to a bottom listview. When I click on Remove button, the author selected in listview will be removed from listview.

2- I want to save data in the Books table, and then I want save the data in the Authors_Books table (both in actionCreate in Books controller). From what I've read, I think I have to make a new model for Authors_Books and use it. But, should not this model have a controller?

How I can implement this?

I need help.

Thanks.

you can save into 2 Models(tables) with the controller you are working with.
but you need to have the model for every table you want to perform operations with in order to communicate with database.

Hope this helps a bit. its rough idea to get on....

public function actionCreate()
	{
		$model1=new Model1;
		
		$model2  = Model2::model()->findAll();

		if(isset($_POST['Model1']))
		{
			//var_dump($_REQUEST);die;
			

				if($model->save()){
					//save the record into Model2
					$model2->model1_id  = $model->id;
					
					$model2->model1_name_  = $_POST['Model3']['name'];
					$model2->save();
					

		$this->render('create',array(
				'model1'=>$model1,
				'model2'=>$model2,
				'another3'=>anotherModel::model()->findAll(),

		));

	}

dont mind if you find any errors..

Thanks for the clarification, developer!.

But i don't understand your code very well.

- $model1-> Is it Books model?
- $model2-> Is it Authors model?
- Should not write this

$model1->attributes=$_POST['Model1'];

before save?
- I don't understand the code that comes after

if($model->save()){

.

I'll try and I commented.

Thanks for the replies.

yes $model1 is like Books model.

But you have a model book, isn't? in your folder model.

so at the place of $model1 you write $books, so after the code is :


yes you should do that before saving :

$books->attributes=$_POST['books']

if you save 2 models you can do a transaction, I have a exemple for you :

public function actionCreate() {
        $model = new PePersonne;
        $modelAdresse = new PeAdresse;
        $adresseCreation = false;
        // Uncomment the following line if AJAX validation is needed
        $this->performAjaxValidation(array($model, $modelAdresse));
        
        if (isset($_POST['PeAdresse']) || isset($_POST['PePersonne'])) {
            $transaction = $model->dbConnection->beginTransaction();
            try {
                if (isset($_POST['PeAdresse'])) {
                    $modelAdresse->attributes = $_POST['PeAdresse'];
                    $valid = $modelAdresse->validate();

                    if ($valid && PeAdresse::AdresseIsSet($modelAdresse->attributes)) {
                        $modelAdresse->adresse_id = PeAdresse::getNewUID();
                        $modelAdresse->save();
                        $adresseCreation = true;
                    }
                }
                if (isset($_POST['PePersonne'])) {
                    
                    $model->attributes = $_POST['PePersonne'];
                    $valid = $model->validate();
                    if ($valid) {
                        if ($adresseCreation) {
                            $model->fk_adresse_priv = $modelAdresse->adresse_id;
                        }
                        $model->personne_id = PePersonne::getNewUID();
                        $model->fk_type_pers = UTILISATEUR;
                        $model->save();
                    }
                }
                // gestion des profils
                if (!empty($_POST['PePersonne']['listProfils'])){                  
                    AdPersonneProfil::model()->deleteAll(array('condition' => 'fk_personne=:personneId', 'params' => array(':personneId' => $model->personne_id)));
                    foreach ($_POST['PePersonne']['listProfils'] as  $value) {          
                        $modelProfil = new AdPersonneProfil;                       
                        $modelProfil->fk_profil = $value;                        
                        $modelProfil->fk_personne = $model->personne_id;                      
                        $modelProfil->save();
                    }
                       
                }
                // FIN -- gestion des profils
 
                $transaction->commit();
                Yii::app()->user->setFlash('messageToDisplay', yii::t('messages', 'okCreation'));
                $this->redirect(array('admin', 'id' => $model->personne_id));
            } catch (Exception $e) {
                $transaction->rollback();
                Yii::app()->user->setFlash('messageToDisplay', yii::t('messages', 'erreurCreation'));
            }
        }

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

yon can use $model->save(); for create and update.
as you did $books->attributes=$_POST['books'], $model->save() will create or update your table books with new values.

I hope I have help you even if my english is very bad !

Good morning!!

Thanks for replies!

Thanks to them and to this thread Multiple Models I get save the data.

But still not working as I want.

1- The data is saved correctly, but I need a list with buttons for adding and removing some IdAuthors in Authors_Books table.

2- When I update the data, I have to re-pass all three models to update form, how is it right?

3- In admin form I must show all AuthorName related with IdBook, and I don't display them.

My code:

BooksController:

public function actionCreate()
    {
$modelBooks=new Books;       
        $modelAB=new AuthorsBooks();          
        $modelAuthors=new Authors;     
        
        if (isset($_POST['Books']) || 
                isset($_POST['AuthorsBooks']))
        {
            $transaction = $Books->dbConnection->beginTransaction();
            
            try 
            {
                $Books->attributes=$_POST['Books'];

                if($Books->save())            
                {
                    $AuthorsBooks->attributes=$_POST['AuthorsBooks'];
                    $AuthorsBooks->IdBook=$Books->IdBook;
                    
                    if($AuthorsBooks->save())
                    {
                        $transaction->commit();
                        $this->redirect(array('view','id'=>$Books->IdBook));
                    }
                }
            } catch (Exception $e) {
                $transaction->rollback();
                Yii::app()->user->setFlash('Error.', yii::t('messages', 'erreurCreation'));
            }
        }
        
        $this->render('create',array(
                                    'Books'=>$Books,

                                    'Authors'=>$Authors,
                    ));
}

public function actionUpdate($id)
    {
$Books=$this->loadModel($id);

        // Uncomment the following line if AJAX validation is needed
        // $this->performAjaxValidation($model);

        if(isset($_POST['Books']))
        {
            $Books->attributes=$_POST['Books'];
            
            if($Books->save())
                $this->redirect(array('view','id'=>$Books->IdBooks));

        $this->render('update',array('Books'=>$Books,));

    )); 

I will try things to see if I succeed. Any help is welcome, lol.

Good morning again!

Well, after I following this example Example, I got almost what I want.

But the AJAX code fail.

When I click in gridview A, I get an error: "Request failed: error." and I don't know why. Therefore, the B gridview doesn't refresh.

Here my code:

views/Books/admin.php

<?php
    /* @var $this BooksController */
    /* @var $model Books */

    $this->breadcrumbs=array(
                            'Books'=>array('index'),
                            'Manage',
    );

    $this->menu=array(
                    array('label'=>'List', 'url'=>array('index')),
                    array('label'=>'New', 'url'=>array('create')),
    );

    Yii::app()->clientScript->registerScript('search', "
                                            $('.search-button').click(function(){
                                                    $('.search-form').toggle();
                                                    return false;
                                            });
                                            $('.search-form form').submit(function(){
                                                    $.fn.yiiGridView.update('books-grid', {
