Save data in two tables in CakePHP

Question

I have a simple form in Cake :

I want to save the informations in the users and companies tables .

Users Table :

Companies table :

I'm in need to get two sql queries .

First of all : - Insert the new users with a new company id which will be created in companies table .

For instance with this case, testza,

users : (new entry) testza password company id (new if of the new company entry)

companies (new entry) : Id (3) Creaz (name) 500 000 (revenue_generated) .

I guess i'm clear :

companies/signup (view)

<div class="page-header">

    <h1>Company Registration</h1>

</div>

<?php echo $this->Form->create('Company'); ?>

        <?php echo $this->Form->input('User.username',array('label'=>'Login')); ?>

        <?php echo $this->Form->input('User.password',array('label'=>'Password')); ?>

        <?php echo $this->Form->input('User.passwordconfirm',array('label'=>'Confirm password','type'=>'password')); ?>

        <hr>

        <?php echo $this->Form->input('Company.company_id', 
        array(
            'label'=>'Company',
            'options' => $companies,
            'empty' => 'Select Company Name'
        ));
        ?>

        <?php echo $this->Form->input('Company.revenue_generated',array('label'=>'Revenue Generated')); ?>

<?php echo $this->Form->end('Envoyer'); ?>

the action signup of the Controller CompaniesController

<?php

class CompaniesController extends AppController{

    public $uses = array('User');

    public function signup() {

        $this->loadModel('Company');

        $companies = $this->Company->find('list'); //we get the authors from the database

        $this->set('companies', $companies);

        if($this->request->is('post') || $this->request->is('put') ){

            $d = $this->request->data['User'];
            $c = $this->request->data['Company'];

            if($d['password'] != $d['passwordconfirm']){

                $this->Session->setFlash("Les mots de passes ne correspondent pas","notif",array('type'=>'error'));

            }

            else{

                if(empty($d['password']))

                    unset($d['password']);

                if($this->User->save($d) || $this->Company->save($c)){

                    $this->Session->setFlash("L'utilisateur a bien été enregistré","notif");

                }

            }

        }
    }
..............

User Model :

<?php 

class User extends AppModel{

    public $actsAs = array('Containable'); 

     public $belongsTo = array(        
        'Town' => array(
            'className' => 'Town'
        ),
        'Company' => array(
            'className' => 'Company'
        )
    ); 

    public $recursive = -1; 

    public $order = 'User.id DESC';

    public $validate = array(

        'username' => array(

            'rule'       => 'isUnique',

            'allowEmpty' => false,

            'message'    => "Ce nom d'utilisateur est déja pris"

        ),

        'password' => array(

            'rule'       => 'notEmpty',

            'message'    => "Vous ne pouvez pas entrer de mot de pase"

        )

    );

    public function beforeSave($options = array()){

        if(!empty($this->data['User']['password'])){

            $this->data['User']['password'] = AuthComponent::password($this->data['User']['password']);

        }

        return true; 

    }

}

Company Model :

<?php 

class Company extends AppModel{

    public $validate = array(
        'revenue_generated' => array(
            'rule' =>'notEmpty',
            'message' => 'Enter Your Generated Revenue.',
            'required' => true
        )
    );

}

Answer 1

Since you are going to use an existing company already in the database from the drop down menu, try saving both models at the same time with Model::saveAssociated(). This will save both records at once for you, and insert the Company id, automatically into the foreign key for the users table: User.company_id on successful save.

Replace your two save() function calls with one call to saveAssociated():

if($this->User->saveAssociated($data)) {
    //do something after save.
}

Here is a complete example using your existing code:

$this->set('companies', $this->Company->find('list'));

if($this->request->is(array('post', 'put'))) {

    //Dont need to seperate this anymore
    //$d = $this->request->data['User'];
    //$c = $this->request->data['Company'];

    if($this->request->data['User']['password'] != $this->request->data['User']['passwordconfirm']){
        $this->Session->setFlash("Les mots de passes ne correspondent pas","notif",array('type'=>'error'));
    } else {

        if(empty($this->request->data['User']['password']))
            unset($this->request->data['User']['password']);

        if($this->User->saveAssociated($this->request->data)){
            $this->Session->setFlash("L'utilisateur a bien été enregistré","notif");
        }
    }
}

The Company model is also missing the hasMany relationship for User. Add this to Company model:

public $hasMany = array('User');

Refer to Cake Manual here for documentation on SaveAssociated(): http://book.cakephp.org/2.0/en/models/saving-your-data.html#model-saveassociated-array-data-null-array-options-array

Answer 2

here is the solution i suggest and i work with, start by saving the company first to generat the id the save the user :

if($this->Company->save($this->request->data['Company'])){
$this->Company->User->save($this->request->data['User']); // if save doesn't work try $this->Company->User->saveAll($this->request->data['User']);
...
}

update : add the hasmany relation in the company model :

public $hasMany = array(
        'User' => array(
            'className' => 'User',
            'foreignKey' => 'company_id',
            'dependent' => false,
            'conditions' => '',
            'fields' => '',
            'order' => '',
            'limit' => '',
            'offset' => '',
            'exclusive' => '',
            'finderQuery' => '',
            'counterQuery' => ''
        )
    );

hope ut helps.
