Class DbAcl

DbAcl implements an ACL control system in the database. ARO's and ACO's are structured into trees and a linking table is used to define permissions. You can install the schema for DbAcl with the Schema Shell.

$aco and $aro parameters can be slash delimited paths to tree nodes.

eg. controllers/Users/edit

Would point to a tree structure like

controllers
        Users
                edit

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
