Method Detail
beforeFindsource public
beforeFind( Model $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') )));

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

setup( Model $Model , array $settings array() )

_addToWhitelistsource 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

Parameters
-

mixed
An array value will replace the value of $results - any other value will be ignored.
afterSavesource public
afterSave( Model $model , boolean $created , array $options array() )
afterSave is called after a model is saved.
Parameters
-

$options
optional array() - Options passed from Model::save().
Returns
boolean
bool
See
Model::save()
afterValidatesource 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
beforeDeletesource 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.
beforeSavesource public
beforeSave( Model $model , array $options array() )

Parameters
-
Model
$model
- Model using this behavior
- array
$options

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

Methods inherited from Object
_mergeVarssource 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.
_setsource 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.
_stopsource 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
dispatchMethodsource 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
logsource public
log( string $msg , integer $type LOG_ERR , null|string|array $scope null )
Convenience method to write a message to CakeLog. See CakeLog::write() for more information on writing to logs.
Parameters
- string
$msg
- Log message
- integer
$type
optional LOG_ERR - Error type constant. Defined in app/Config/core.php.
- null|string|array
$scope
optional null - The scope(s) a log message is being created in. See CakeLog::config() for more information on logging scopes.
Returns
boolean
Success of log write
requestActionsource 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.
toStringsource public
toString( )
Object-to-string conversion. Each class can override this method as necessary.
Returns
string
The name of this class
Properties summary
Properties inherited from ModelBehavior
$mapMethodssource
public array
Allows the mapping of preg-compatible regular expressions to public or private methods in this class, where the array key is a /-delimited regular expression, and the value is a class method. Similar to the functionality of the findBy* / findAllBy* magic methods.
array()
$settingssource
public array
Contains configuration settings for use with individual model objects. This is used because if multiple models use this Behavior, each will use the same object instance. Individual model settings should be stored as an associative array, keyed off of the model name.

Model::$alias
array()
