Multiple Service Layer and Repository Pattern managed with Events -

i know topic regarting service layer , repository pattern, "i still haven't found i'm looking for" ( u2 docet ... )

i'm working complex application dozen of services , repositories; pattern, show example, this:

controller $return = $this->getuserservice()->findall();  class userservice public function findall() return $this->getuserrepository()->findall();  class userrepository /** *  * @return collection of usermodel */ public function findall(){ $sql = "select * `user` ";         return $this->fetchall($sql); } 

so, every table in database, there these entities:

{entity}service {entity}repository {entity}model 

in controller, have collection of usermodel objects, returned repository layer through service layer.

all sounds good, until work single table; how work if have work multiple services/repositories?

1) question number 1

let want send email after operation , increase stats; in controller, probabply in service layer better, cause in service layer should add business logic.

so write:

controller     $this->getuserservice()->dosomething($params);  class userservice     public function dosomething($params);      $ok = $this->getuserrepository()->do($params);     $this->getmailservice()->sendemail($params);     $this->getstatsservice()->updatestats($params);      return true; 

in way, have add many services access single service; right? if these 3 operations strictly correlated , right way cause can move service method elsewhere without problems ( api context, web context), , operations remanin intact. problem have inject services within userservice, example using service container. think? how proceed if have perform many operations together? use controller instead?

2) question 2

i have collection of usermodels fetched pattern ( controller > service > repository > service > controller) let have usermodel dependency, example list of posts written user, , want able load list of posts in lazy way.

how can archieve this? user repository has returned rows user table database, , don't want add joins, cause not want load posts @ every request. problem post models belongs service > repository ( postservice , postrepository )

i solve problems using events; basically, every requests dependency object fire event.

class usermodel     protected $posts = null;      public function setposts($posts)     $this->posts = $posts;      public function getposts()         if(is_null($this->posts))             $this->loadposts();         return $this->posts;      protected function loadpost()         event::trigger(event::load_post,['targetmodel' => $this]);  controller      $users = $this->getuserservice()->findall();     foreach($users $user){         $posts = $user->getposts();     }     ...   $eventemitter->on(event::load_post, function(event $e) {     $targetmodel = $e->getdata('targetmodel');     if (!method_exists($targetmodel, 'setposts')) {         return false;     }     $posts = $e->getcontainer()     ->get('post-service')     ->findbyuserid($targetmodel->getuserid());     $targetmodel->setposts($posts);     return true; }); 

basically, when ask list of posts model , related model property null ( not empty, null ), trigger event, passing object i'm in. trigger call function has been registered during application bootstrap, call right services , call targetmodel setter load objects.

in way, solve many problems; can separate services , avoid many services within other services. can reuse code; let have many entities $posts, can create posttrait property , setter , getter, , use in entities has manage list of posts.

what think solution? if there way load object different repository in lazy way, without mixing repositories, tell me!

thanks in advance!
