Saving belongsToMany associations in CakePHP 3

Vote count:

I have encountered a problem whilst saving belongsToMany associations and the data being saved is a combination of existing entities and new entities.

The data array is as follows:

$data = [
    'tags' => [
        ['label' => 'Some new tag'],
        ['label' => 'Another new tag'],
        '_ids' => [1, 2] 
    ]
];

Is it that these two methods of saving this association cannot be used together?

I have tried creating a data array where each entity is its own array item like the following:

$data = [
    'tags' => [
        ['label' => 'Some new tag'],
        ['label' => 'Another new tag'],
        ['id' => 1], 
        ['id' => 2] 
    ]
];

But when it is just ids this does not create new associations. Do I need to handle the creation of new entities first and then create the associations using the ['_ids'] methods, or is there something wrong with my data array?
