Method Summary
-
beforeFind() public
Runs before a find() operation. Used to allow 'contain' setting as part of the find call, like this:
-
contain() public
Unbinds all relations from a model except the specified ones. Calling this function without parameters unbinds all related models.
-
containments() public
Process containments for model. -
containmentsMap() public
Build the map of containments -
fieldDependencies() public
Calculate needed fields to fetch the required bindings for the given model. -
resetBindings() public
Permanently restore the original binding settings of given model, useful for restoring the bindings after using 'reset' => false as part of the contain call.
-
setup() public
Initiate behavior for the model using specified settings.
Method Detail
beforeFind() public ¶
beforeFind( object $Model , array $query )
Runs before a find() operation. Used to allow 'contain' setting as part of the find call, like this:
Model->find('all', array('contain' => array('Model1', 'Model2')));
{{{ Model->find('all', array('contain' => array( 'Model1' => array('Model11', 'Model12'), 'Model2', 'Model3' => array( 'Model31' => 'Model311', 'Model32', 'Model33' => array('Model331', 'Model332') ))); }}}
Parameters
- object $Model
- Model using the behavior
- array $query
- Query parameters as set by cake
Returns
Overrides
contain() public ¶
contain( object $Model )
Unbinds all relations from a model except the specified ones. Calling this function without parameters unbinds all related models.
Parameters
- object $Model
- Model on which binding restriction is being applied
Link
containments() public ¶
containments( object $Model , array $contain , array $containments = array() , boolean $throwErrors = null )
Process containments for model.
Parameters
- object $Model
- Model on which binding restriction is being applied
- array $contain
- Parameters to use for restricting this model
- array $containments optional array()
- Current set of containments

Returns
Containments
containmentsMap() public ¶
containmentsMap( array $containments )
Build the map of containments
Parameters
- array $containments
- Containments
Returns
Built containments
fieldDependencies() public ¶
fieldDependencies( object $Model , array $map , mixed $fields = array() )
Calculate needed fields to fetch the required bindings for the given model.
Parameters
- object $Model
- Model
- array $map
- Map of relations for given model
- mixed $fields optional array()
- If array, fields to initially load, if false use $Model as primary model
Returns
Fields
resetBindings() public ¶
resetBindings( object $Model )
Permanently restore the original binding settings of given model, useful for restoring the bindings after using 'reset' => false as part of the contain call.
Parameters
- object $Model
- Model on which to reset bindings
setup() public ¶
setup( object $Model , array $settings = array() )
Initiate behavior for the model using specified settings.
Available settings:
- recursive: (boolean, optional) set to true to allow containable to automatically determine the recursiveness level needed to fetch specified models, and set the model recursiveness to this level. setting it to false disables this feature. DEFAULTS TO: true
- notices: (boolean, optional) issues E_NOTICES for bindings referenced in a containable call that are not valid. DEFAULTS TO: true
- autoFields: (boolean, optional) auto-add needed fields to fetch requested bindings. DEFAULTS TO: true
Parameters
- object $Model
- Model using the behavior
- array $settings optional array()
- Settings to override for model.

_addToWhitelist() public ¶
_addToWhitelist( object $model , string $field )
If $model's whitelist property is non-empty, $field will be added to it. Note: this method should only be used in beforeValidate or beforeSave to ensure that it only modifies the whitelist for the current save operation. Also make sure you explicitly set the value of the field which you are allowing.
Parameters
- object $model
- Model using this behavior
- string $field
- Field to be added to $model's whitelist
afterDelete() public ¶
afterDelete( object $model )
After delete callback
Parameters
- object $model
- Model using this behavior
afterFind() public ¶
afterFind( object $model , mixed $results , boolean $primary )
After find callback. Can be used to modify any results returned by find and findAll.
Parameters
- object $model
- Model using this behavior
- mixed $results
- The results of the find operation
- boolean $primary
- Whether this model is being queried directly (vs. being queried as an association)
Returns
An array value will replace the value of $results - any other value will be ignored.
afterSave() public ¶
afterSave( object $model , boolean $created )
After save callback
Parameters
- object $model
- Model using this behavior
- boolean $created
- True if this save created a new record
beforeDelete() public ¶
beforeDelete( object $model , boolean $cascade = true )
Before delete callback
Parameters
- object $model
- Model using this behavior
- boolean $cascade optional true
- If true records that depend on this record will also be deleted
Returns
False if the operation should abort. Any other result will continue.
beforeSave() public ¶
beforeSave( object $model )
Before save callback
Parameters
- object $model
- Model using this behavior
Returns
False if the operation should abort. Any other result will continue.
beforeValidate() public ¶
beforeValidate( object $model )
Before validate callback
Parameters
- object $model
- Model using this behavior
Returns
False if the operation should abort. Any other result will continue.
cleanup() public ¶
cleanup( object $model )
Clean up any initialization this behavior has done on a model. Called when a behavior is dynamically detached from a model using Model::detach().
Parameters
- object $model
- Model using this behavior
See
dispatchMethod() public ¶
dispatchMethod( string $model , array $method , $params = array() )
Overrides Object::dispatchMethod to account for PHP4's broken reference support
Parameters
- string $model
- $method Name of the method to call

- $params Parameter list to use when calling $method
- $params optional array()
Returns

Methods inherited from Object
Object() public ¶
Object( )
A hack to support __construct() on PHP 4 Hint: descendant classes have no PHP4 class_name() constructors, so this constructor gets called first and calls the top-layer __construct() which (if present) should call parent::__construct()
Returns
__openPersistent() public ¶
__openPersistent( string $name , string $type = null )
Open the persistent class file for reading Used by Object::_persist()
Parameters
- string $name
- Name of persisted class
- string $type optional null
- Type of persistance (e.g: registry)
_persist() public ¶
_persist( string $name , string $return , $object , $type = null )
Checks for a persistent class file, if found file is opened and true returned If file is not found a file is created and false returned If used in other locations of the model you should choose a unique name for the persistent file There are many uses for this method, see manual for examples
Parameters
- string $name
- name of the class to persist

- $object the object to persist
- $object
- $type optional null
Returns
Success
_savePersistent() public ¶
_savePersistent( string $name , object $object )
You should choose a unique name for the persistent file
There are many uses for this method, see manual for examples
Parameters
- string $name

Returns
true on save, throws error if file can not be created

Allows setting of multiple properties of the object in a single line of code. Will only set properties that are part of a class declaration.
