Saving hasMany relation in add form in cakephp 3

Question

I have a Shop that can have many Offers and I would like to create a new Shop and a number of Offers in the add form of the Shop.

From what I read the fields should look something like this

<?= $this->Form->control('offers.0.name', ['value' => 'awesome']); ?>

But I get a form error because the shop_id for the Offer is missing.

How do I structure my form to save the Shop and the Offers and cake fills in the newly created shop_id for the Offers.

@kicaj so far I don't use patchEntity(). I was hoping I can solve this with the correct form structure. — Chriss Baumfleisch, Jan 10 '18 at 11:30
If You wan save relation models You should use `patchEntity` with association params — kicaj, Jan 10 '18 at 11:42
According to cake naming convention, the primary key of tables should be "id". Post your Relation and table structure please — bikash.bilz, Jan 10 '18 at 11:58

//In Controller,

$shopTable=TableRegistry::get('Shop');
$entity = $shopTable->newEntity($this->request->getData(), [
           'associated' => [
                'Offers'
            ]
          ]);

OR, Same as patchEntity with associated ,you can do.
