Class Table

Represents a single database table.

Exposes methods for retrieving data out of it, and manages the associations this table has to other tables. Multiple instances of this class can be created for the same database table with different aliases, this allows you to address your database structure in a richer and more expressive way.

Retrieving data

The primary way to retrieve data is using Table::find(). See that method for more information.

Dynamic finders

In addition to the standard find($type) finder methods, CakePHP provides dynamic finder methods. These methods allow you to easily set basic conditions up. For example to filter users by username you would call

$query = $users->findByUsername('mark');

You can also combine conditions on multiple fields using either Or or And:

$query = $users->findByUsernameOrEmail('mark', '[email protected]');

Bulk updates/deletes

You can use Table::updateAll() and Table::deleteAll() to do bulk updates/deletes. You should be aware that events will not be fired for bulk updates/deletes.

Callbacks/events

Table objects provide a few callbacks/events you can hook into to augment/replace find operations. Each event uses the standard event subsystem in CakePHP

beforeFind(Event $event, Query $query, ArrayObject $options, boolean $primary) Fired before each find operation. By stopping the event and supplying a return value you can bypass the find operation entirely. Any changes done to the $query instance will be retained for the rest of the find. The $primary parameter indicates whether or not this is the root query, or an associated query.
buildValidator(Event $event, Validator $validator, string $name) Allows listeners to modify validation rules for the provided named validator.
buildRules(Event $event, RulesChecker $rules) Allows listeners to modify the rules checker by adding more rules.
beforeRules(Event $event, EntityInterface $entity, ArrayObject $options, string $operation) Fired before an entity is validated using the rules checker. By stopping this event, you can return the final value of the rules checking operation.
afterRules(Event $event, EntityInterface $entity, ArrayObject $options, bool $result, string $operation) Fired after the rules have been checked on the entity. By stopping this event, you can return the final value of the rules checking operation.
beforeSave(Event $event, EntityInterface $entity, ArrayObject $options) Fired before each entity is saved. Stopping this event will abort the save operation. When the event is stopped the result of the event will be returned.
afterSave(Event $event, EntityInterface $entity, ArrayObject $options) Fired after an entity is saved.
beforeDelete(Event $event, EntityInterface $entity, ArrayObject $options) Fired before an entity is deleted. By stopping this event you will abort the delete operation.
afterDelete(Event $event, EntityInterface $entity, ArrayObject $options) Fired after an entity has been deleted.

fields
conditions
order
limit
offset
page
group
having
contain
join

Usage

Using the options array:

$query = $articles->find('all', [
  'conditions' => ['published' => 1],
  'limit' => 10,
  'contain' => ['Users', 'Comments']
]);

Using the builder interface:

$query = $articles->find()
  ->where(['published' => 1])
  ->limit(10)
  ->contain(['Users', 'Comments']);

Calling finders

The find() method is the entry point for custom finder methods. You can invoke a finder by specifying the type:

$query = $articles->find('published');

Would invoke the findPublished method.

Parameters

string $type optional 'all': the type of query to perform
array|ArrayAccess $options optional []: An array that will be passed to Query::applyOptions()

Returns

Cake\ORM\Query
The query builder

Implementation of

Cake\ORM\Query $query: The query to find with
array $options: The options to use for the find

Returns

Cake\ORM\Query
The query builder

findList() public ¶

findList( Cake\ORM\Query $query , array $options )

Sets up a query object so results appear as an indexed array, useful for any place where you would want a list such as for populating input select boxes.

When calling this finder, the fields passed are used to determine what should be used as the array key, value and optionally what to group the results by. By default the primary key for the model is used for the key, and the display field as value.

The results of this finder will be in the following form:

[
 1 => 'value for id 1',
 2 => 'value for id 2',
 4 => 'value for id 4'
]

You can specify which property will be used as the key and which as value by using the $options array, when not specified, it will use the results of calling primaryKey and displayField respectively in this table:

$table->find('list', [
 'keyField' => 'name',
 'valueField' => 'age'
]);

Results can be put together in bigger groups when they share a property, you can customize the property to use for grouping by setting groupField:

$table->find('list', [
 'groupField' => 'category_id',
]);

When using a groupField results will be returned in this format:

[
 'group_1' => [
     1 => 'value for id 1',
     2 => 'value for id 2',
 ]
 'group_2' => [
     4 => 'value for id 4'
 ]
]

array $options: The options for the find

Returns

Cake\ORM\Query
The query builder

findOrCreate() public ¶

findOrCreate( array $search , callable $callback = null )

Using the attributes defined in $search a find() will be done to locate an existing record. If records matches the conditions, the first record will be returned.

If no record can be found, a new entity will be created with the $search properties. If a callback is provided, it will be called allowing you to define additional default values. The new entity will be saved and returned.

Parameters

array $search: The criteria to find existing records by.
callable $callback optional null: A callback that will be invoked for newly created entities. This callback will be called before the entity is persisted.

Returns

Cake\Datasource\EntityInterface
An entity.

findThreaded() public ¶

findThreaded( Cake\ORM\Query $query , array $options )

Results for this finder will be a nested array, and is appropriate if you want to use the parent_id field of your model data to build nested results.

Values belonging to a parent row based on their parent_id value will be recursively nested inside the parent row values using the children property

You can customize what fields are used for nesting results, by default the primary key and the parent_id fields are used. If you wish to change these defaults you need to provide the keys keyField or parentField in $options:

$table->find('threaded', [
 'keyField' => 'id',
 'parentField' => 'ancestor_id'
]);

dependent: Set to true if you want CakePHP to cascade deletes to the associated table when an entity is removed on this table. Set to false if you don't want CakePHP to remove associated data, for when you are using database constraints.
cascadeCallbacks: Set to true if you want CakePHP to fire callbacks on cascaded deletes. If false the ORM will use deleteAll() to remove data. When true records will be loaded and then deleted.
conditions: array with a list of conditions to filter the join with
sort: The order in which results for this association should be returned
saveStrategy: Either 'append' or 'replace'. When 'append' the current records are appended to any records in the database. When 'replace' associated records not in the current set will be removed. If the foreign key is a null able column or if dependent is true records will be orphaned.
strategy: The strategy to be used for selecting results Either 'select' or 'subquery'. If subquery is selected the query used to return results in the source table will be used as conditions for getting rows in the target table.
finder: The finder method to use when loading records from this association. Defaults to 'all'.

This method will return the association object that was built.

Parameters

string $associated: the alias for the target table. This is used to uniquely identify the association
array $options optional []: list of options to configure the association definition

Returns

Cake\ORM\Association\HasMany

hasOne() public ¶

hasOne( string $associated , array $options = [] )

Creates a new HasOne association between this table and a target table. A "has one" association is a 1-1 relationship.

Target table can be inferred by its name, which is provided in the first argument, or you can either pass the class name to be instantiated or an instance of it directly.

The options array accept the following keys:

className: The class name of the target table object
targetTable: An instance of a table object to be used as the target table
foreignKey: The name of the field to use as foreign key, if false none will be used
dependent: Set to true if you want CakePHP to cascade deletes to the associated table when an entity is removed on this table. Set to false if you don't want CakePHP to remove associated data, for when you are using database constraints.
cascadeCallbacks: Set to true if you want CakePHP to fire callbacks on cascaded deletes. If false the ORM will use deleteAll() to remove data. When true records will be loaded and then deleted.
conditions: array with a list of conditions to filter the join with
joinType: The type of join to be used (e.g. LEFT)
strategy: The loading strategy to use. 'join' and 'select' are supported.
finder: The finder method to use when loading records from this association. Defaults to 'all'. When the strategy is 'join', only the fields, containments, and where conditions will be used from the finder.

This method will return the association object that was built.

Parameters

string $associated: the alias for the target table. This is used to uniquely identify the association
array $options optional []: list of options to configure the association definition

Returns

Cake\ORM\Association\HasOne

implementedEvents() public ¶

implementedEvents( )

By implementing the conventional methods a table class is assumed to be interested in the related event.

Override this method if you need to add non-conventional event listeners. Or if you want you table to listen to non-standard events.

The conventional method map is:

Model.beforeMarshal => beforeMarshal
Model.beforeFind => beforeFind
Model.beforeSave => beforeSave
Model.afterSave => afterSave
Model.afterSaveCommit => afterSaveCommit
Model.beforeDelete => beforeDelete
Model.afterDelete => afterDelete

Model.afterRules => afterRules

Returns

array

Implementation of

Cake\Event\EventListenerInterface::implementedEvents()

initialize() public ¶

initialize( array $config )

Initialize a table instance. Called after the constructor.

You can use this method to define associations, attach behaviors define validation and do any other initialization logic you need.

public function initialize(array $config)
 {
     $this->belongsTo('Users');
     $this->belongsToMany('Tagging.Tags');
     $this->primaryKey('something_else');
 }

Parameters

array $config: Configuration options passed to the constructor

loadInto() public ¶

loadInto( Cake\Datasource\EntityInterface|array $entities , array $contain )

Loads the specified associations in the passed entity or list of entities by executing extra queries in the database and merging the results in the appropriate properties.

Example:

$user = $usersTable->get(1);
$user = $usersTable->loadInto($user, ['Articles.Tags', 'Articles.Comments']);
echo $user->articles[0]->title;

You can also load associations for multiple entities at once

Example:

$users = $usersTable->find()->where([...])->toList();
$users = $usersTable->loadInto($users, ['Articles.Tags', 'Articles.Comments']);
echo $user[1]->articles[0]->title;

The properties for the associations to be loaded will be overwritten on each entity.

Parameters

Cake\Datasource\EntityInterface|array $entities: a single entity or list of entities
array $contain: A contain() compatible array.

Returns

Cake\Datasource\EntityInterface|array

See

\Cake\ORM\Query::contain()

marshaller() public ¶

marshaller( )

Get the object used to marshal/convert array data into objects.

Override this method if you want a table object to use custom marshalling logic.

Returns

Cake\ORM\Marshaller

See

Cake\ORM\Marshaller

newEntities() public ¶

newEntities( array $data , array $options = [] )

Create a list of entities + associated entities from an array.

By default all the associations on this table will be hydrated. You can limit which associations are built, or include deeper associations using the options parameter:

$articles = $this->Articles->newEntities(
  $this->request->data(),
  ['associated' => ['Tags', 'Comments.Users']]
);

You can limit fields that will be present in the constructed entities by passing the fieldList option, which is also accepted for associations:

$articles = $this->Articles->newEntities($this->request->data(), [
 'fieldList' => ['title', 'body'],
 'associated' => ['Tags', 'Comments.Users' => ['fieldList' => 'username']]
 ]
);

You can use the Model.beforeMarshal event to modify request data before it is converted into entities.

Parameters

array $data: The data to build an entity with.
array $options optional []: A list of options for the objects hydration.

Returns

array
An array of hydrated records.

Implementation of

Cake\Datasource\RepositoryInterface::newEntities()

newEntity() public ¶

newEntity( array|null $data = null , array $options = [] )

Create a new entity + associated entities from an array.

By default all the associations on this table will be hydrated. You can limit which associations are built, or include deeper associations using the options parameter:

$article = $this->Articles->newEntity(
  $this->request->data(),
  ['associated' => ['Tags', 'Comments.Users']]
);

You can limit fields that will be present in the constructed entity by passing the fieldList option, which is also accepted for associations:

$article = $this->Articles->newEntity($this->request->data(), [
 'fieldList' => ['title', 'body'],
 'associated' => ['Tags', 'Comments.Users' => ['fieldList' => 'username']]
]
);

The fieldList option lets remove or restrict input data from ending up in the entity. If you'd like to relax the entity's default accessible fields, you can use the accessibleFields option:

$article = $this->Articles->newEntity(
  $this->request->data(),
  ['accessibleFields' => ['protected_field' => true]]
);

By default, the data is validated before being passed to the new entity. In the case of invalid fields, those will not be present in the resulting object. The validate option can be used to disable validation on the passed data:

$article = $this->Articles->newEntity(
  $this->request->data(),
  ['validate' => false]
);

You can also pass the name of the validator to use in the validate option. If null is passed to the first param of this function, no validation will be performed.

You can use the Model.beforeMarshal event to modify request data before it is converted into entities.

Parameters

array|null $data optional null: The data to build an entity with.
array $options optional []: A list of options for the object hydration.

Returns

Cake\Datasource\EntityInterface

Implementation of

Cake\Datasource\RepositoryInterface::newEntity()

patchEntities() public ¶

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

Merges each of the elements passed in $data into the entities found in $entities respecting the accessible fields configured on the entities. Merging is done by matching the primary key in each of the elements in $data and $entities.

Those 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.

You can limit fields that will be present in the merged entities by passing the fieldList option, which is also accepted for associations:

$articles = $this->Articles->patchEntities($articles, $this->request->data(), [
 'fieldList' => ['title', 'body'],
 'associated' => ['Tags', 'Comments.Users' => ['fieldList' => 'username']]
 ]
);

You can use the Model.beforeMarshal event to modify request data before it is converted into entities.

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 []: A list of options for the objects hydration.

Returns

array

Implementation of

Cake\Datasource\RepositoryInterface::patchEntities()

patchEntity() public ¶

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

Merges the passed $data into $entity respecting the accessible fields configured on the entity. Returns the same entity after being altered.

You can limit fields that will be present in the merged entity by passing the fieldList option, which is also accepted for associations:

$article = $this->Articles->patchEntity($article, $this->request->data(), [
 'fieldList' => ['title', 'body'],
 'associated' => ['Tags', 'Comments.Users' => ['fieldList' => 'username']]
 ]
);

By default, the data is validated before being passed to the entity. In the case of invalid fields, those will not be assigned to the entity. The validate option can be used to disable validation on the passed data:

$article = $this->patchEntity($article, $this->request->data(),[
 'validate' => false
]);

You can use the Model.beforeMarshal event to modify request data before it is converted into entities.

Parameters

$this->removeBehavior('Tree');

Parameters

string $name: The alias that the behavior was added with.

See

Cake\ORM\Behavior

save() public ¶

save( Cake\Datasource\EntityInterface $entity , array|ArrayAccess $options = [] )

Persists an entity based on the fields that are marked as dirty and returns the same entity after a successful save or false in case of any error.

Options

The options array accepts the following keys:

atomic: Whether to execute the save and callbacks inside a database transaction (default: true)
checkRules: Whether or not to check the rules on entity before saving, if the checking fails, it will abort the save operation. (default:true)
associated: If true it will save all associated entities as they are found in the passed $entity whenever the property defined for the association is marked as dirty. Associated records are saved recursively unless told otherwise. If an array, it will be interpreted as the list of associations to be saved. It is possible to provide different options for saving on associated table objects using this key by making the custom options the array value. If false no associated records will be saved. (default: true)
checkExisting: Whether or not to check if the entity already exists, assuming that the entity is marked as not new, and the primary key has been set.

Events

When saving, this method will trigger four events:

Model.beforeRules: Will be triggered right before any rule checking is done for the passed entity if the checkRules key in $options is not set to false. Listeners will receive as arguments the entity, options array and the operation type. If the event is stopped the rules check result will be set to the result of the event itself.
Model.afterRules: Will be triggered right after the checkRules() method is called for the entity. Listeners will receive as arguments the entity, options array, the result of checking the rules and the operation type. If the event is stopped the checking result will be set to the result of the event itself.
Model.beforeSave: Will be triggered just before the list of fields to be persisted is calculated. It receives both the entity and the options as arguments. The options array is passed as an ArrayObject, so any changes in it will be reflected in every listener and remembered at the end of the event so it can be used for the rest of the save operation. Returning false in any of the listeners will abort the saving process. If the event is stopped using the event API, the event object's result property will be returned. This can be useful when having your own saving strategy implemented inside a listener.
Model.afterSave: Will be triggered after a successful insert or save, listeners will receive the entity and the options array as arguments. The type of operation performed (insert or update) can be determined by checking the entity's method isNew, true meaning an insert and false an update.
Model.afterSaveCommit: Will be triggered after the transaction is commited for atomic save, listeners will receive the entity and the options array as arguments.

This method will determine whether the passed entity needs to be inserted or updated in the database. It does that by checking the isNew method on the entity. If the entity to be saved returns a non-empty value from its errors() method, it will not be saved.

Saving on associated tables

This method will by default persist entities belonging to associated tables, whenever a dirty property matching the name of the property name set for an association in this table. It is possible to control what associations will be saved and to pass additional option for saving them.

// Only save the comments association
$articles->save($entity, ['associated' => ['Comments']);

// Save the company, the employees and related addresses for each of them.
// For employees do not check the entity rules
$companies->save($entity, [
  'associated' => [
    'Employees' => [
      'associated' => ['Addresses'],
      'checkRules' => false
    ]
  ]
]);

// Save no associations
$articles->save($entity, ['associated' => false]);

Parameters

Cake\Datasource\EntityInterface $entity: the entity to be saved
array|ArrayAccess $options optional []: The options to use when saving.

Returns

Cake\Datasource\EntityInterface|boolean

Implementation of

Cake\Datasource\RepositoryInterface::save()

schema() public ¶

schema( array|Cake\Database\Schema\Table|null $schema = null )

Returns the schema table object describing this table's properties.

If an \Cake\Database\Schema\Table is passed, it will be used for this table instead of the default one.

If an array is passed, a new \Cake\Database\Schema\Table will be constructed out of it and used as the schema for this table.

Parameters

array|Cake\Database\Schema\Table|null $schema optional null: New schema to be used for this table

Returns

Cake\Database\Schema\Table

table() public ¶

table( string|null $table = null )

Returns the database table name or sets a new one

Parameters

string|null $table optional null: the new table name

Returns

string

updateAll() public ¶

updateAll( array $fields , mixed $conditions )

Update all matching records.

Parameters

array $fields: A hash of field => new value.
mixed $conditions: Conditions to be used, accepts anything Query::where() can take.

Returns

integer
Count Returns the affected rows.

Implementation of

Cake\Datasource\RepositoryInterface::updateAll()

validateUnique() public ¶

validateUnique( mixed $value , array $options , array $context = null )

Validator method used to check the uniqueness of a value for a column. This is meant to be used with the validation API and not to be called directly.

Example:

$validator->add('email', [
 'unique' => ['rule' => 'validateUnique', 'provider' => 'table']
])

Unique validation can be scoped to the value of another column:

$validator->add('email', [
 'unique' => [
     'rule' => ['validateUnique', ['scope' => 'site_id']],
     'provider' => 'table'
 ]
]);

In the above example, the email uniqueness will be scoped to only rows having the same site_id. Scoping will only be used if the scoping field is present in the data to be validated.

Parameters

mixed $value: The value of column to be checked for uniqueness
array $options: The options array, optionally containing the 'scope' key. May also be the validation context if there are no options.
array $context optional null: Either the validation context or null.

Returns

boolean
true if the value is unique

Cake\Event\Event

eventManager() public ¶

eventManager( Cake\Event\EventManager $eventManager = null )

Returns the Cake\Event\EventManager manager instance for this object.

You can use this instance to register any new listeners or callbacks to the object events, or create your own events and trigger them at will.

Parameters

Cake\Event\EventManager $eventManager optional null: the eventManager to set

Returns

Cake\Event\EventManager

Methods used from Cake\Datasource\RulesAwareTrait

checkRules() public ¶

checkRules( Cake\Datasource\EntityInterface $entity , string $operation = RulesChecker::CREATE , ArrayObject|array $options = null )

Returns whether or not the passed entity complies with all the rules stored in the rules checker.

Parameters

Cake\Datasource\EntityInterface $entity: The entity to check for validity.
string $operation optional RulesChecker::CREATE: The operation being run. Either 'create', 'update' or 'delete'.
ArrayObject|array $options optional null: The options To be passed to the rules.

Returns

boolean

rulesChecker() public ¶

A RulesChecker object is used to test an entity for validity on rules that may involve complex logic or data that needs to be fetched from relevant datasources.

Returns

Cake\Datasource\RulesChecker

See

Cake\Datasource\RulesChecker

Methods used from Cake\Validation\ValidatorAwareTrait

validationDefault() public ¶

validationDefault( Cake\Validation\Validator $validator )

Returns the default validator object. Subclasses can override this function to add a default validation set to the validator object.

Parameters

Cake\Validation\Validator $validator: The validator that can be modified to add some rules to it.

Returns

Cake\Validation\Validator

validator() public ¶

validator( string $name = null , Cake\Validation\Validator $validator = null )

Returns the validation rules tagged with $name. It is possible to have multiple different named validation sets, this is useful when you need to use varying rules when saving from different routines in your system.

There are two different ways of creating and naming validation sets: by creating a new method inside your own Table subclass, or by building the validator object yourself and storing it using this method.

For example, if you wish to create a validation set called 'forSubscription', you will need to create a method in your Table subclass as follows:

public function validationForSubscription($validator)
{
 return $validator
 ->add('email', 'valid-email', ['rule' => 'email'])
 ->add('password', 'valid', ['rule' => 'notBlank'])
 ->requirePresence('username');
}

Otherwise, you can build the object by yourself and store it in the Table object:

$validator = new \Cake\Validation\Validator($table);
$validator
 ->add('email', 'valid-email', ['rule' => 'email'])
 ->add('password', 'valid', ['rule' => 'notBlank'])
 ->allowEmpty('bio');
$table->validator('forSubscription', $validator);

You can implement the method in validationDefault in your Table subclass should you wish to have a validation set that applies in cases where no other set is specified.

Parameters

string $name optional null: the name of the validation set to return
Cake\Validation\Validator $validator optional null: The validator instance to store, use null to get a validator.

Returns

Cake\Validation\Validator
