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

Model $Model: Model using the behavior
array $query: Query parameters as set by cake

Returns

array

Overrides

ModelBehavior::beforeFind()

resetBindings() public ¶

resetBindings( Model $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

Model $Model: Model on which to reset bindings

setup() public ¶

setup( Model $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

Model $Model: Model using the behavior
array $settings optional array(): Settings to override for model.

Overrides

ModelBehavior::setup()

_addToWhitelist() protected ¶

_addToWhitelist( Model $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

Model $model: Model using this behavior
string $field: Field to be added to $model's whitelist

afterDelete() public ¶

afterDelete( Model $model )

After delete is called after any delete occurs on the attached model.

Parameters

Model $model: Model using this behavior

afterFind() public ¶

afterFind( Model $model , mixed $results , boolean $primary )

After find callback. Can be used to modify any results returned by find.

Parameters

Model $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

mixed
An array value will replace the value of $results - any other value will be ignored.

afterSave() public ¶

afterSave( Model $model , boolean $created )

afterSave is called after a model is saved.

Parameters

Model $model: Model using this behavior
boolean $created: True if this save created a new record

Returns

boolean

afterValidate() public ¶

afterValidate( Model $model )

afterValidate is called just after model data was validated, you can use this callback to perform any data cleanup or preparation if needed

Parameters

Model $model: Model using this behavior

Returns

mixed
False will stop this event from being passed to other behaviors

beforeDelete() public ¶

beforeDelete( Model $model , boolean $cascade = true )

Before delete is called before any delete occurs on the attached model, but after the model's beforeDelete is called. Returning false from a beforeDelete will abort the delete.

Parameters

Model $model: Model using this behavior
boolean $cascade optional true: If true records that depend on this record will also be deleted

Returns

mixed
False if the operation should abort. Any other result will continue.

beforeSave() public ¶

beforeSave( Model $model )

beforeSave is called before a model is saved. Returning false from a beforeSave callback will abort the save operation.

Parameters

Model $model: Model using this behavior

Returns

mixed
False if the operation should abort. Any other result will continue.

beforeValidate() public ¶

beforeValidate( Model $model )

beforeValidate is called before a model is validated, you can use this callback to add behavior validation rules into a models validate array. Returning false will allow you to make the validation fail.

Parameters

Model $model: Model using this behavior

Returns

mixed
False or null will abort the operation. Any other result will continue.

cleanup() public ¶

cleanup( Model $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

Model $model: Model using this behavior

See

BehaviorCollection::detach()

onError() public ¶

onError( Model $model , string $error )

DataSource error callback

Parameters

Model $model: Model using this behavior
string $error: Error generated in DataSource

__construct() public ¶

__construct( )

constructor, no-op

_mergeVars() protected ¶

_mergeVars( array $properties , string $class , boolean $normalize = true )

Merges this objects $property with the property in $class' definition. This classes value for the property will be merged on top of $class'

This provides some of the DRY magic CakePHP provides. If you want to shut it off, redefine this method as an empty function.

Parameters

array $properties: The name of the properties to merge.
string $class: The class to merge the property with.
boolean $normalize optional true: Set to true to run the properties through Hash::normalize() before merging.

_set() protected ¶

_set( array $properties = array() )

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.

Parameters

array $properties optional array(): An associative array containing properties and corresponding values.

_stop() protected ¶

_stop( integer|string $status = 0 )

Stop execution of the current script. Wraps exit() making testing easier.

Parameters

integer|string $status optional 0: see http://php.net/exit for values

dispatchMethod() public ¶

dispatchMethod( string $method , array $params = array() )

Calls a method on this object with the given parameters. Provides an OO wrapper for call_user_func_array

Parameters

string $method: Name of the method to call
array $params optional array(): Parameter list to use when calling $method

Returns

mixed
Returns the result of the method call

log() public ¶

log( string $msg , integer|string $type = LOG_ERR )

Convenience method to write a message to CakeLog. See CakeLog::write() for more information on writing to logs.

Parameters

string $msg: Log message.
integer|string $type optional LOG_ERR: Type of message being written. Either a valid LOG_* constant or a string matching the recognized levels.

Returns

boolean
Success of log write.

See

CakeLog::write()

requestAction() public ¶

requestAction( string|array $url , array $extra = array() )

Calls a controller's method from any location. Can be used to connect controllers together or tie plugins into a main application. requestAction can be used to return rendered views or fetch the return value from controller actions.

Under the hood this method uses Router::reverse() to convert the $url parameter into a string URL. You should use URL formats that are compatible with Router::reverse()

Passing POST and GET data

POST and GET data can be simulated in requestAction. Use $extra['url'] for GET data. The $extra['data'] parameter allows POST data simulation.

Parameters

string|array $url: String or array-based URL. Unlike other URL arrays in CakePHP, this URL will not automatically handle passed and named arguments in the $url parameter.
array $extra optional array(): if array includes the key "return" it sets the AutoRender to true. Can also be used to submit GET/POST data, and named/passed arguments.

Returns

mixed

Boolean true or false on success/failure, or contents of rendered action if 'return' is set in $extra.

toString() public ¶

toString( )

Object-to-string conversion. Each class can override this method as necessary.

Returns

string
The name of this class
