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.

Events

Table objects emit several events during as life-cycle hooks during find, delete and save operations. All events use the CakePHP event package:

Model.beforeFind 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 this is the root query, or an associated query.
Model.buildValidator Allows listeners to modify validation rules for the provided named validator.
Model.buildRules Allows listeners to modify the rules checker by adding more rules.
Model.beforeRules 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.
Model.afterRules 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.
Model.beforeSave 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.
Model.afterSave Fired after an entity is saved.
Model.afterSaveCommit Fired after the transaction in which the save operation is wrapped has been committed. It’s also triggered for non atomic saves where database operations are implicitly committed. The event is triggered only for the primary table on which save() is directly called. The event is not triggered if a transaction is started before calling save.
Model.beforeDelete Fired before an entity is deleted. By stopping this event you will abort the delete operation.
Model.afterDelete Fired after an entity has been deleted.

Callbacks

You can subscribe to the events listed above in your table classes by implementing the lifecycle methods below:

beforeFind(EventInterface $event, SelectQuery $query, ArrayObject $options, boolean $primary)
beforeMarshal(EventInterface $event, ArrayObject $data, ArrayObject $options)
afterMarshal(EventInterface $event, EntityInterface $entity, ArrayObject $options)
buildValidator(EventInterface $event, Validator $validator, string $name)
buildRules(RulesChecker $rules)
beforeRules(EventInterface $event, EntityInterface $entity, ArrayObject $options, string $operation)
afterRules(EventInterface $event, EntityInterface $entity, ArrayObject $options, bool $result, string $operation)
beforeSave(EventInterface $event, EntityInterface $entity, ArrayObject $options)
afterSave(EventInterface $event, EntityInterface $entity, ArrayObject $options)
afterSaveCommit(EventInterface $event, EntityInterface $entity, ArrayObject $options)
beforeDelete(EventInterface $event, EntityInterface $entity, ArrayObject $options)
afterDelete(EventInterface $event, EntityInterface $entity, ArrayObject $options)

For HasMany and HasOne associations records will be removed based on the dependent option. Join table records in BelongsToMany associations will always be removed. You can use the cascadeCallbacks option when defining associations to change how associated data is deleted.

Options

atomic Defaults to true. When true the deletion happens within a transaction.
checkRules Defaults to true. Check deletion rules before deleting the record.

Events

Model.beforeDelete Fired before the delete occurs. If stopped the delete will be aborted. Receives the event, entity, and options.
Model.afterDelete Fired after the delete has been successful. Receives the event, entity, and options.
Model.afterDeleteCommit Fired after the transaction is committed for an atomic delete. Receives the event, entity, and options.

The options argument will be converted into an \ArrayObject instance for the duration of the callbacks, this allows listeners to modify the options used in the delete operation.

Parameters

Cake\Datasource\EntityInterface $entity: The entity to remove.
array<string, mixed> $options optional: The options for the delete.

Returns

bool

deleteAll() ¶ public

deleteAll(Cake\Database\Expression\QueryExpressionClosure|array|string|null $conditions): int

This method will not execute on associations' cascade attribute. You should use database foreign keys + ON CASCADE rules if you need cascading deletes combined with this method.

Parameters

Cake\Database\Expression\QueryExpressionClosure|array|string|null $conditions: Conditions to be used, accepts anything Query::where() can take.

Returns

int

deleteMany() ¶ public

Creates a new Query for this repository and applies some defaults based on the type of search that was selected.

Model.beforeFind event

Each find() will trigger a Model.beforeFind event for all attached listeners. Any listener can set a valid result set using $query

By default, following special named arguments are recognized which are used as select query options:

fields
conditions
order
limit
offset
page
group
having
contain
join

Usage

$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.

This will invoke the findPublished method:

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

Typed finder arguments

Finders must have a SelectQuery instance as their 1st argument and any additional parameters as needed.

Here, the finder "findByCategory" has an integer $category parameter:

function findByCategory(SelectQuery $query, int $category): SelectQuery
{
    return $query;
}

This finder can be called as:

$query = $articles->find('byCategory', $category);

or using named arguments as:

$query = $articles->find(type: 'byCategory', category: $category);

Parameters

string $type optional: the type of query to perform
mixed ...$args: Arguments that match up to finder-specific parameters

Returns

Cake\ORM\Query\SelectQuery

findAll() ¶ public

findAll(Cake\ORM\Query\SelectQuery $query): Cake\ORM\Query\SelectQuery

Returns the query as passed.

Parameters

Cake\ORM\Query\SelectQuery $query: The query to find with

Returns

Cake\ORM\Query\SelectQuery

findAssociation() ¶ protected

findAssociation(string $name): Cake\ORM\Association|null

Returns an association object configured for the specified alias if any.

The name argument also supports dot syntax to access deeper associations.

$users = $this->getAssociation('Articles.Comments.Users');

Parameters

string $name: The alias used for the association.

Returns

Cake\ORM\Association|null

findList() ¶ public

findList(Cake\ORM\Query\SelectQuery $query, Closure|array|string|null $keyField = null, Closure|array|string|null $valueField = null, Closure|array|string|null $groupField = null, string $valueSeparator = ' '): Cake\ORM\Query\SelectQuery

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, when not specified, it will use the results of calling primaryKey and displayField respectively in this table:

$table->find('list', keyField: 'name', valueField: 'age');

The valueField can also be an array, in which case you can also specify the valueSeparator option to control how the values will be concatenated:

$table->find('list',  valueField: ['first_name', 'last_name'], valueSeparator: ' | ');

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

[
 1 => 'John | Doe',
 2 => 'Steve | Smith'
]

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'
 ]
]

A find() will be done to locate an existing record using the attributes defined in $search. 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.

If your find conditions require custom order, associations or conditions, then the $search parameter can be a callable that takes the Query as the argument, or a \Cake\ORM\Query\SelectQuery object passed as the $search parameter. Allowing you to customize the find results.

Options

The options array is passed to the save method with exception to the following keys:

atomic: Whether to execute the methods for find, save and callbacks inside a database transaction (default: true)
defaults: Whether to use the search criteria as default values for the new entity (default: true)

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 keyField, parentField or nestingKey arguments:

$table->find('threaded', keyField: 'id', parentField: 'ancestor_id', nestingKey: 'children');

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.

If a validator has not been set earlier, this method will build a valiator using a method inside your class.

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');
}

$validator = $this->getValidator('forSubscription');

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.

If a $name argument has not been provided, the default validator will be returned. You can configure your default validator name in a DEFAULT_VALIDATOR class constant.

Parameters

string|null $name optional: The name of the validation set to return.

Returns

Cake\Validation\Validator

newEntities() ¶ public

newEntities(array $data, array<string, mixed> $options = []): arrayCake\Datasource\EntityInterface>

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

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

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

$articles = $this->Articles->newEntities($this->request->getData(), [
 'fields' => ['title', 'body', 'tags', 'comments'],
 'associated' => ['Tags', 'Comments.Users' => ['fields' => '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<string, mixed> $options optional: A list of options for the objects hydration.

Returns

arrayCake\Datasource\EntityInterface>

newEntity() ¶ public

newEntity(array $data, array<string, mixed> $options = []): Cake\Datasource\EntityInterface

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->getData(),
  ['associated' => ['Tags', 'Comments.Users']]
);

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

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

The fields 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->getData(),
  ['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->getData(),
  ['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 $data: The data to build an entity with.
array<string, mixed> $options optional: A list of options for the object hydration.

Returns

Cake\Datasource\EntityInterface

patchEntities() ¶ public

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 fields option, which is also accepted for associations:

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

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

Parameters

iterableCake\Datasource\EntityInterface> $entities: the entities that will get the data merged in
array $data: list of arrays to be merged into the entities
array<string, mixed> $options optional: A list of options for the objects hydration.

Returns

arrayCake\Datasource\EntityInterface>

patchEntity() ¶ public

patchEntity(Cake\Datasource\EntityInterface $entity, array $data, array<string, mixed> $options = []): Cake\Datasource\EntityInterface

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 fields option, which is also accepted for associations:

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

$article = $this->Articles->patchEntity($article, $this->request->getData(), [
  'associated' => [
    'Tags' => ['accessibleFields' => ['*' => true]]
  ]
]);

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->getData(),[
 'validate' => false
]);

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

When patching scalar values (null/booleans/string/integer/float), if the property presently has an identical value, the setter will not be called, and the property will not be marked as dirty. This is an optimization to prevent unnecessary field updates when persisting entities.

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<string, mixed> $options optional: A list of options for the object hydration.

atomic: Whether to execute the save and callbacks inside a database transaction (default: true)
checkRules: Whether 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 1st level associated entities as they are found in the passed $entity whenever the property defined for the association is marked as dirty. 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 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 committed 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]);

validateUnique() ¶ public

validateUnique(mixed $value, array<string, mixed> $options, array|null $context = null): bool

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<string, mixed> $options: The options array, optionally containing the 'scope' key. May also be the validation context, if there are no options.
array|null $context optional: Either the validation context or null.

Returns

bool

validationDefault() ¶ public
