The entity to save

array<string, mixed> $nested

Options for deeper associations

array<string, mixed> $options

Original options

Returns

bool

_saveAssociations() protected

_saveAssociations(Cake\ORM\Table $table, Cake\Datasource\EntityInterface $entity, array $associations, array<string, mixed> $options, bool $owningSide): bool

Helper method for saving an association's data.

Parameters

Original options

bool $owningSide

Compared with association classes' isOwningSide method.

InvalidArgumentException
When an unknown alias is used.

add() public

add(string $alias, Cake\ORM\Association $association): Cake\ORM\Association

Parameters

string $alias

The association alias

Cake\ORM\Association $association

The association to add.

Returns

Cake\ORM\Association

cascadeDelete() public

cascadeDelete(Cake\Datasource\EntityInterface $entity, array<string, mixed> $options): bool

Cascade a delete across the various associations. Cascade first across associations for which cascadeCallbacks is true.

Parameters

Cake\Datasource\EntityInterface $entity

The entity to delete associations for.

array<string, mixed> $options

The options used in the delete operation.

Returns

bool

fetchTable() public

fetchTable(string|null $alias = null, array<string, mixed> $options = []): Cake\ORM\Table

Parameters

string|null $alias optional

The options you want to build the table with. If a table has already been loaded the registry options will be ignored.

Returns

Cake\ORM\Table

Throws

Cake\Core\Exception\CakeException
If `$alias` argument and `$defaultTable` property both are `null`.
