cakephp 3.x Saving Nested (deep) Association

Question

I have product data coming from a 3rd party service call that I then create an object from and save to my MySQL DB. My models are as follows:

\'products\' hasMany>>

Answer 1

The product_sku_attributes data is not being marshalled, it's still an array of arrays, and not an array of entities, hence it's not being saved.

Just like when saving entities, creating/patching them with associated data by default only works for first level associations. Deeper nested associations require to specify them via the associated option, ie:

$entity = $products->newEntity($product_data[0], [
    'associated' => [
        'ProductSkus.ProductSkuAttributes'
    ]
]);

$products->save($entity, [
    'associated' => [
        'ProductSkus.ProductSkuAttributes'
    ]
]);
