zend framework2 - ZF2 - BjyAuthorize - How to Get Rules and Guards from a Database -


i'm using bjyauthorize zend framework2 implement authorization , able integrate roles database. want rules , guards data base tables. how can this?

the easiest method , "the trick" here to:

  1. get rules , guards same array format shown in example configuration. after reading records database, in whatever format raw database data is, process match same guard format in configuration. (my answer goes detail on how doctrine orm, should give idea other db engines. substitute "db read" operation fave database engine)

  2. inject rules in proper format bjyauthorize expects (because made them so), bjyauthorize\guard\controller, within your_module_name\factory\doctrinecontrollerguardadapterfactory, write. bjy's controller treat rules if rules came configuration*, , not suspect difference.

  3. step , enjoy!

this construct need write in own module:

namespace your_module_name\factory;  /**  * see "how , register factory" in zf2 config  * below in answer.  */ class [custom]controllerguardadapterfactory  {     public function createservice(servicelocatorinterface $servicelocator)     {         /**          * retrieve rules favorive db engine (or anything)          *          * (you may use $servicelocator config db engine)          * (you may use $servicelocator db engine)          * (you may use $servicelocator orm entity db engine)          * (or may hack db connection , retrieval in other way)          *          * hell, may read them text file using php's file() method          * , not use $servicelocator @          *          * may hardcode rules right here matters          */                     $rules = ... //array(...);           /**           * inject them bjy's controller          *          * rules must in same format in bjy config, or puke.          * see how ['guards'][\bjyauthorize\guard\controller::class] constructed           * in bjy configuration example          */                      return new \bjyauthorize\guard\controller($rules, $servicelocator);      } } 

now watch , observe how mind-numbingly complicated can made! (modeled after bjy's own mechanisms)

this zf2, oo & bjy "configuration hell", folks, nothing special otherwise. welcome zf2 , bjy , orm configuration hell. welcome.

detailed answer - how implement?

write adapter factory, reads rules database, , injects them bjyauthorize's controller guard. effect same if rules being read ['guards'][\bjyauthorize\guard\controller::class]

what?

the way bjyauthorize's controller guard works takes rules in format (format specified ['guards']['bjyauthorize\guard\controller']), , uses rules populate acl. computes resources rules , loads acl well. if didn't, have write own resource provider so.

so task becomes:

  • load rules database , transform rules format bjyauthorize expects. can done in own rule provider, much one.
  • you can use factory load particular db , storage class configuration arrays module.config.php file. put mine under ['guards']['your_module_name_controller_guard_adapter'].
'guards' => array(         'your_module_name_controller_guard_adapter' => array(             'object_manager' => 'doctrine.entity_manager.orm_default',             'rule_entity_class' => 'your_module_name\entity\objectrepositoryprovider'         ) ) 
  • (cont) put under guards opposed rule_providers, because dealing here not pure rule provider. guard provider, or "an adapter gets rules out of objectrepositoryprovider, , injects them controller guard". this factory should similar this, except loading rules, not roles. injecting rules controller, in next step.
  • inject rules controller, done here

example implementation details (from q/a in comments)

more on last point of "injecting rules controller". 2 steps: 1) make sure have (or will) generate rules somehow (that's hard step ). 2) inject rules controller (that's easier step). actual injection done this

$rules = __magic__;  //get rules out of somewhere, somehow. return new controller($rules, $servicelocator); //$rules injection point 

see code block below own implementation, last line in block line gave above here.

namespace your_module_name\factory;  use bjyauthorize\exception\invalidargumentexception; use zend\servicemanager\factoryinterface; use zend\servicemanager\servicelocatorinterface; use your_module_name\provider\rule\doctrineruleprovider;    //this one's own use bjyauthorize\guard\controller;  class doctrinecontrollerguardadapterfactory implements factoryinterface {     public function createservice(servicelocatorinterface $servicelocator)     {         //just setting our config, move along move along...         $config = $servicelocator->get('config');         $config = $config['bjyauthorize'];          //making sure have proper entries in our config...          //move along "nothing see" here....         if (! isset($config['guards']['your_module_name_controller_guard_adapter'])) {             throw new invalidargumentexception(                 'config "your_module_name_controller_guard_adapter" not set'             );         }          //yep load our own module config here         $providerconfig = $config['guards']['your_module_name_controller_guard_adapter'];          //more specific checks on config         if (! isset($providerconfig['rule_entity_class'])) {             throw new invalidargumentexception('rule_entity_class not set in your_module_name guards config.');         }          if (! isset($providerconfig['object_manager'])) {             throw new invalidargumentexception('object_manager not set in your_module_name guards config.');         }          /* @var $objectmanager \doctrine\common\persistence\objectmanager */         $objectmanager = $servicelocator->get($providerconfig['object_manager']);          //orp -- object repository provider         //here our class preps object repository         $orp=new doctrineruleprovider($objectmanager->getrepository($providerconfig['rule_entity_class']));          //here pull rules out of object we've created above         //rules in same format bjyauthorize expects         $rules=$orp->getrules();          //here pass our rules bjyauthorize's own guard controller.           //it not know difference if got rules config or doctrine or elsewhere,           //as long $rules in form expects.         return new controller($rules, $servicelocator);      } } 

doctrineruleprovider

namespace your_module_name\provider\rule;  use doctrine\common\persistence\objectrepository; use bjyauthorize\provider\rule\providerinterface;  /**  * guard provider based on {@see \doctrine\common\persistence\objectrepository}  */ class doctrineruleprovider implements providerinterface {     /**      * @var \doctrine\common\persistence\objectrepository      */     protected $objectrepository;      /**      * @param \doctrine\common\persistence\objectrepository $objectrepository                  */     public function __construct(objectrepository $objectrepository)     {         $this->objectrepository = $objectrepository;     }      /**      * here read rules db , put them form bjyauthorize's controller.php understands      */     public function getrules()     {         //read object store set of (role, controller, action)          $result = $this->objectrepository->findall();          //transform object bjyauthorize understand         $rules = array();         foreach ($result $key => $rule)         {             $role=$rule->getrole();             $controller=$rule->getcontroller();             $action=$rule->getaction();                          if ($action==='all')    //action ommitted             {                 $rules[$controller]['roles'][] = $role;                 $rules[$controller]['controller'] = array($controller);             }             else             {                 $rules[$controller.':'.$action]['roles'][]=$role;                 $rules[$controller.':'.$action]['controller']=array($controller);                 $rules[$controller.':'.$action]['action']=array($action);             }                                }              return array_values($rules);     } } 

q: how , register factory doctrinecontrollerguardadapterfactory

a: try path: module\your_module_name\config\module.config.php , have

'service_manager' => array(     'factories' => array(         'your_module_name_controller_guard_adapter' => \your_module_name\factory\doctrinecontrollerguardadapterfactory::class     ) ) 
  • note: your_module_name. thing on left of => sign "the key", , can want be. convention in bjy is similar actual class names , paths. , thing on right of => actual qualified namespace class want call with key.
