many() public ¶
many( array $data , array $options [] )
Hydrate many entities and their associated data.
Options:
- validate: Set to false to disable validation. Can also be a string of the validator ruleset to be applied. Defaults to true/default.
- associated: Associations listed here will be marshalled as well. Defaults to null.
- fieldList: (deprecated) Since 3.4.0. Use fields instead
- fields: A whitelist of fields to be assigned to the entity. If not present, the accessible fields list in the entity will be used. Defaults to null.
- accessibleFields: A list of fields to allow or deny in entity accessible fields. Defaults to null
- forceNew: When enabled, belongsToMany associations will have 'new' entities created when primary key values are set, and a record does not already exist. Normally primary key on missing entities would be ignored. Defaults to false.
Parameters
- array $data
- The data to hydrate.
- array $options optional []
- List of options
Returns

\Cake\ORM\Entity::$_accessible
merge() public ¶
merge( Cake\Datasource\EntityInterface $entity , array $data , array $options [] )
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: (deprecated) Since 3.4.0. Use fields instead
- fields: 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
See
mergeMany() public ¶
mergeMany( Cake\Datasource\EntityInterface[]|Traversable $entities , array $data , array $options [] )
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.
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.
Options:
- 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.
- associated: Associations listed here will be marshalled as well.
- fieldList: (deprecated) Since 3.4.0. Use fields instead
- fields: 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
-
Cake\Datasource\EntityInterface[]|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
See
one() public ¶
one( array $data , array $options [] )
Hydrate one entity and its associated data.
Options:
- validate: Set to false to disable validation. Can also be a string of the validator ruleset to be applied. Defaults to true/default.
- associated: Associations listed here will be marshalled as well. Defaults to null.
- fieldList: (deprecated) Since 3.4.0. Use fields instead.
- fields: A whitelist of fields to be assigned to the entity. If not present, the accessible fields list in the entity will be used. Defaults to null.
- accessibleFields: A list of fields to allow or deny in entity accessible fields. Defaults to null
- forceNew: When enabled, belongsToMany associations will have 'new' entities created when primary key values are set, and a record does not already exist. Normally primary key on missing entities would be ignored. Defaults to false.
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 = $marshaller->one($data, [ 'associated' => ['Tags' => ['onlyIds' => true]] ]);
