link()source public

link( Cake\Datasource\EntityInterface $sourceEntity , array $targetEntities , array $options [] )

Associates the source entity to each of the target entities provided by creating links in the junction table. Both the source entity and each of the target entities are assumed to be already persisted, if they are marked as new or their status is unknown then an exception will be thrown.

When using this method, all entities in $targetEntities will be appended to the source entity's property corresponding to this association object.

This method does not check link uniqueness.

Example:

$newTags = $tags->find('relevant')->toArray();
$articles->association('tags')->link($article, $newTags);

$article->get('tags') will contain all tags in $newTags after liking

Parameters

the row belonging to the source side of this association

list of entities belonging to the target side of this association

array $options optional []

list of options to be passed to the internal save call

replaceLinks()source public

replaceLinks( Cake\Datasource\EntityInterface $sourceEntity , array $targetEntities , array $options [] )

Replaces existing association links between the source entity and the target with the ones passed. This method does a smart cleanup, links that are already persisted and present in $targetEntities will not be deleted, new links will be created for the passed target entities that are not already in the database and the rest will be removed.

For example, if an article is linked to tags 'cake' and 'framework' and you pass to this method an array containing the entities for tags 'cake', 'php' and 'awesome', only the link for cake will be kept in database, the link for 'framework' will be deleted and the links for 'php' and 'awesome' will be created.

Existing links are not deleted and created again, they are either left untouched or updated so that potential extra information stored in the joint row is not lost. Updating the link row can be done by making sure the corresponding passed target entity contains the joint property with its primary key and any extra information to be stored.

On success, the passed $sourceEntity will contain $targetEntities as value in the corresponding property for this association.

This method assumes that links between both the source entity and each of the target entities are unique. That is, for any given row in the source table there can only be one link in the junction table pointing to any other given row in the target table.

Additional options for new links to be saved can be passed in the third argument, check Table::save() for information on the accepted options.

Example:

$article->tags = [$tag1, $tag2, $tag3, $tag4];
$articles->save($article);
$tags = [$tag1, $tag3];
$articles->association('tags')->replaceLinks($article, $tags);

$article->get('tags') will contain only [$tag1, $tag3] at the end

Parameters

Cake\Datasource\EntityInterface $sourceEntity

an entity persisted in the source table for this association

array $targetEntities

list of entities from the target table to be linked

array $options optional []

list of options to be passed to the internal save/delete calls when persisting/updating new links, or deleting existing ones

Returns

boolean
success

Throws

InvalidArgumentException

if non persisted entities are passed or if any of them is lacking a primary key value

saveAssociated()source public

saveAssociated( Cake\Datasource\EntityInterface $entity , array $options [] )

Takes an entity from the source table and looks if there is a field matching the property name for this association. The found entity will be saved on the target table for this association by passing supplied $options

When using the 'append' strategy, this function will only create new links between each side of this association. It will not destroy existing ones even though they may not be present in the array of entities to be saved.

When using the 'replace' strategy, existing links will be removed and new links will be created in the joint table. If there exists links in the database to some of the entities intended to be saved by this method, they will be updated, not deleted.

Parameters

Cake\Datasource\EntityInterface $entity

an entity from the source table

array $options optional []

options to be passed to the save method in the target table
