Export data from query with related table

[nicocins]

Dear all,

I have an issue when I export data with csvview.

I want to export data from two associated table :

$this->response = $this->response->withDownload(‘Inventaire.csv’);
$this->loadModel(‘Details’);
$details = $this->Details->find(‘all’)->contain([‘Scans’])
->where([‘Scans.idInventory’ => $idInventory]);

$details->select([‘Scans.nb_elements’, ‘Details.ean’, ‘Details.qty’]);
$this->set(compact(‘details’));
$this->viewBuilder()
->setClassName(‘CsvView.Csv’)
->setOptions([
‘serialize’ => ‘details’,
‘delimiter’ => ‘;’,
‘enclosure’ => ‘’,
‘bom’ => true
]);

When I export data from only one table (Details) it works, but when I add “Scans” table I got this message:

Notice (8): Array to string conversion [ ROOT\vendor\friendsofcake\cakephp-csvview\src\View\CsvView.php , line 333 ]

It’s like he s trying to display an array instead of my field Scans.nb_elements.

I check my variable $details and everything is ok.

Could you help me about this ?

Thanks in advance.

Hi @nicocins ,

I was faced with the same issue and found the following solution. Assuming you have Devices and DeviceStatuses tables. The following did help me:

$data = $this->Devices->find()
                ->select([
                    'Devices.id', 'Devices.name', 'Devices.ip_address',
                    'status' => 'DeviceStatuses.name'
                ])
                ->contain([                   
                    'DeviceStatuses'
                ]);

With 'status' => 'DeviceStatuses.name' I was finally able to use the depending information and export it to csv.

And in the $_extract array I put the following - as already mentioned in the doc:

$_extract = [
                'Devices.id',
                'Devices.name',
                'Devices.ip_address',
                function (array $row) {
                    return $row['name'];
                },

Hope this helps

It used to work in the older version, why is not working in this one? Need to update plugin so can work with associated models again.

We should add a note into the docs here I guess.
