As you can see, the field shoots_id is required, which I would have thought would be automatically passed down (although at this point it hasn't executed any MySQL).
I feel I may have gone about this the wrong way but have spent 2 full days trying to get it right. One of those days was me trying to work out why after baking it had named a lot of the references to ShootMeta to ShootMetum, I thought it had actually corrupted it.
One of the biggest issues I have is knowing where to use shoot_meta, ShootMeta, shootmeta, shootmetum, ShootMetum etc. It feels like a bit of a minefield!
/Update
A dump of the save object below. It is clearly assigning it, it just seems to not be executing it in the SQL?
'shoot_meta' => [
(int) 0 => object(App\Model\Entity\ShootMetum) {
'new' => false,
'accessible' => [
'shoots_id' => true,
'meta_key' => true,
'meta_value' => true
],
'properties' => [
'meta_key' => 'photographer_spaces',
'meta_value' => '123',
'shoot_id' => '2',
'id' => '3'
],
'dirty' => [],
'original' => [],
'virtual' => [],
'errors' => [],
'repository' => 'ShootMeta'
},

Answer 1

Found it.
It is referring to shoot_id when i debug the save
'shoot_meta' => [
(int) 0 => object(App\Model\Entity\ShootMetum) {
'new' => false,
'accessible' => [
'shoots_id' => true,
'meta_key' => true,
'meta_value' => true
],
'properties' => [
'meta_key' => 'photographer_spaces',
'meta_value' => '123',
'shoot_id' => '2',
'id' => '3'
],
'dirty' => [],
'original' => [],
'virtual' => [],
'errors' => [],
'repository' => 'ShootMeta'
},
for some reason it was using the singular name for the association. Changed in the Shoots.php model.
From
$this->hasMany('ShootMeta');
To
$this->hasMany('ShootMeta',[
'foreignKey' => 'shoots_id'
]);

Answer 2

Remove the validation rule for shoots_id. Validation is for data that is posted from the form, and in this case the foreignKey cannot be posted from the Form. You already have rules in your buildRules() method for making sure that value is passed before saving, so removing the validation is 100% safe.

Answer 3

i have same problem like this to, for now my solution is sending associated data to other function/methode and save it.
eg
**
public function add() {
$kantor = $this->Kantor->newEntity($this->request->data);
if ($this->request->is('post')) {
$kantor = $this->Kantor->patchEntity($kantor, $this->request->data);
$rgndata = $this->request->data['Telpkantor'];
$this->request->session()->write('rgndata', $rgndata);
if ($this->Kantor->save($kantor)) {
$result = $this->Kantor->save($kantor);
$this->addTelpKantor($rgndata, $result->id);
$this->Flash->success('The kantor has been saved.');
return $this->redirect(['action' => 'index']);
} else {
$this->Flash->error('The kantor could not be saved. Please, try again.');
}
}
$reffKota = $this->Kantor->ReffKota->find('list', ['limit' => 200]);
$statusKantor = $this->Kantor->StatusKantor->find('list', ['limit' => 200]);
$pimpinan = $this->Kantor->Pimpinan->find('list', ['limit' => 200]);
$jenisTelp = $this->Kantor->Telpkantor->Jenistelp->find('list', ['limit' => 200]);
$this->set(compact('kantor', 'reffKota', 'statusKantor', 'pimpinan', 'jenisTelp'));
$this->set('_serialize', ['kantor']);
}
public function addTelpKantor($rgndata = null, $kantor_id=null) {
if (!empty($rgndata[0]['noTelp'])) {
$this->loadModel('Telpkantor');
foreach ($rgndata as $rgndata) {
$rgndata['kantor_id'] =$kantor_id;
$rgndatasave = $this->Telpkantor->newEntity($rgndata);
$this->Telpkantor->save($rgndatasave);
}
}
}
