Merges $data into $entity and recursively does the same for each one of the association names passed in $options. When merging associations, if an entity is not present in the parent entity for a given association, a new one will be created.
mergeMany() public

Merges each of the elements from $data into each of the entities in $entities and recursively does the same for each of the association names passed in $options. When merging associations, if an entity is not present in the parent entity for a given association, a new one will be created.

_mergeBelongsToMany() ¶ protected

_mergeBelongsToMany(Cake\Datasource\EntityInterface $original, Cake\ORM\Association $assoc, array $value, array $options): array

Creates a new sub-marshaller and merges the associated data for a BelongstoMany association.

Parameters

Cake\ORM\Association $assoc: The association to marshall
array $value: The data to hydrate
array $options: List of options.

Returns

array

_mergeJoinData() ¶ protected

_mergeJoinData(Cake\Datasource\EntityInterface $original, Cake\ORM\Association $assoc, array $value, array $options): array

Merge the special _joinData property into the entity set.

Parameters

Cake\Datasource\EntityInterface $original: The original entity
Cake\ORM\Association $assoc: The association to marshall
array $value: The data to hydrate
array $options: List of options.

Returns

array

_normalizeAssociations() ¶ protected

_normalizeAssociations(array $associations): array

Returns an array out of the original passed associations list where dot notation is transformed into nested arrays so that they can be parsed by other routines

Parameters

array $associations: The array of included associations.

Returns

array

_prepareDataAndOptions() ¶ protected

_prepareDataAndOptions(array $data, array $options): array

Returns data and options prepared to validate and marshall.

Parameters

array $data: The data to prepare.
array $options: The options passed to this marshaller.

Returns

array

_validate() ¶ protected

_validate(array $data, array $options, bool $isNew): array

Returns the validation errors for a data set based on the passed options

Parameters

array $data: The data to validate.
array $options: The options passed to this marshaller.
bool $isNew: Whether it is a new entity or one to be updated.

Returns

array

Throws

RuntimeException
If no validator can be created.

many() ¶ public

many(array $data, array $options = []): array

Hydrate many entities and their associated data.

Options:

associated: Associations listed here will be marshalled as well.
fieldList: A whitelist of fields to be assigned to the entity. If not present, the accessible fields list in the entity will be used.
accessibleFields: A list of fields to allow or deny in entity accessible fields.

Parameters

array $data: The data to hydrate.
array $options optional: List of options

Returns

array

merge() ¶ public

merge(Cake\Datasource\EntityInterface $entity, array $data, array $options = []): Cake\Datasource\EntityInterface

Merges $data into $entity and recursively does the same for each one of the association names passed in $options. When merging associations, if an entity is not present in the parent entity for a given association, a new one will be created.

When merging HasMany or BelongsToMany associations, all the entities in the $data array will appear, those that can be matched by primary key will get the data merged, but those that cannot, will be discarded. ids option can be used to determine whether the association must use the _ids format.

Options:

associated: Associations listed here will be marshalled as well.
validate: Whether or not to validate data before hydrating the entities. Can also be set to a string to use a specific validator. Defaults to true/default.
fieldList: A whitelist of fields to be assigned to the entity. If not present the accessible fields list in the entity will be used.
accessibleFields: A list of fields to allow or deny in entity accessible fields.

The above options can be used in each nested associated array. In addition to the above options you can also use the onlyIds option for HasMany and BelongsToMany associations. When true this option restricts the request data to only be read from _ids.

$result = $marshaller->merge($entity, $data, [
  'associated' => ['Tags' => ['onlyIds' => true]]
]);

Parameters

Cake\Datasource\EntityInterface $entity: the entity that will get the data merged in
array $data: key value list of fields to be merged into the entity
array $options optional: List of options.

Returns

Cake\Datasource\EntityInterface

mergeMany() ¶ public

mergeMany(array|Traversable $entities, array $data, array $options = []): array

Merges each of the elements from $data into each of the entities in $entities and recursively does the same for each of the association names passed in $options. When merging associations, if an entity is not present in the parent entity for a given association, a new one will be created.

Records in $data are matched against the entities using the primary key column. Entries in $entities that cannot be matched to any record in $data will be discarded. Records in $data that could not be matched will be marshalled as a new entity.

Options:

associated: Associations listed here will be marshalled as well.
fieldList: A whitelist of fields to be assigned to the entity. If not present, the accessible fields list in the entity will be used.
accessibleFields: A list of fields to allow or deny in entity accessible fields.

Parameters

array|Traversable $entities: the entities that will get the data merged in
array $data: list of arrays to be merged into the entities
array $options optional: List of options.

Returns

array

one() ¶ public

one(array $data, array $options = []): Cake\ORM\Entity

Hydrate one entity and its associated data.

Options:

associated: Associations listed here will be marshalled as well.
fieldList: A whitelist of fields to be assigned to the entity. If not present, the accessible fields list in the entity will be used.
accessibleFields: A list of fields to allow or deny in entity accessible fields.

$result = $marshaller->one($data, [
  'associated' => ['Tags' => ['onlyIds' => true]]
]);

Parameters

array $data: The data to hydrate.
array $options optional: List of options

Returns

Cake\ORM\Entity
