boolean is self-explanatory: it validates whether a field contains a boolean value (i.e. 0, 1, “0″, “1″, false, or true). Example:

var $validate = array('is_enabled' => array('rule' => array('boolean')));

inList ensures that the respective field only contains a value from the defined array. It is case-sensitive, i.e. if you use the rule from the example below, then the value “Red” would be invalid.

var $validate = array('color' => array('rule' => array('inList', array('red', 'green', 'blue'))));

time determines whether a field contains a valid time value. It supports both the 24 hour format (e.g. 08:10:10) and the 12 hour format (e.g. 8:10:10am). The minutes and seconds are optional in both cases.

var $validate = array('starttime' => array('rule' => array('time')));

Another recent change affected View::renderElement(): it has been deprecated in favor of View::element():

$this->renderElement('my_element', array('param1' => 'a value'));

becomes

$this->element('my_element', array('param1' => 'a value'));

I don’t know why View::renderElement() was deprecated and not View::element(), as I think the method name “renderElement” is more expressive than “element”.

Anyway, happy baking :)

On the console the command

cake acl initdb

has been replaced by

cake schema run create DbAcl

In basics.php all load functions have been replaced by App::import(): loadView(), loadModel(), loadController(), loadHelper(), loadPluginHelper(), loadComponent(), loadPluginComponent(), loadBehavior(), loadModels(), loadPluginModels(), and loadControllers().

The function listClasses() has been replaced by Configure::listObjects(), and the implementations of setUri() and setUrl() have been moved to the dispacher and are now called uri() resp. getUrl().

The initialization of the cookie component has changed, it should be configured in the beforeFilter of the controller and therefore the initialize() method should no longer be used.

The implementation of cleanUpFields() has been moved from the controller to Model::deconstruct().

In the model two methods are deprecated: loadInfo() has been replaced by Model::schema() and generateList() by Model::find(‘list’). Also the parameter usage of validates() and invalidFields() has been deprecated, you have to set the $data property instead.

In the form helper the method submitImage() should no longer be used, instead the submit() method can be used.

As there is the form helper for creating form elements, all form-related methods in the HTML helper are deprecated: radio(), password(), textarea(), checkbox(), hidden(), input(), tagValue(), validate(), validateErrors(), and tagErrorMsg().

In the Javascript helper the $safe parameter for the codeBlock() method, plus the parameters $prefix, $postfix, $stringKeys, $quoteKeys, and $q for object() are deprecated.

In the helper class the method setFormTag() has been replaced by setEntity().

The properties $themeElement, $themeLayout, and $themePath are no longer needed in the theme class.

In the file class many methods have been renamed, and therefore the old names are deprecated: getFullPath(), getName(), fileName(), getExt(), getMd5(), getSize(), getOwner(), getGroup(), getChmod(), and getFolder().

The functionality of chmodr() and mkdirr() from the folder class is now handled by chmod() resp. mkdir().

In the router the routes for web services are deprecated: “/rest/”, “/rss/”, “/soap/”, “/xml/”, and “/xmlrpc/”. The same is true for the routes “/bare/” and “/ajax/”.

Last, but not least, the validation constants VALID_NOT_EMPTY, VALID_NUMBER, VALID_EMAIL, and VALID_YEAR are deprecated.
