i'm writing object factory node module in es6. i'm using stamptit library https://github.com/stampit-org/stampit base objects started enhance them , return own objects through factory. lets have these 2 files in '../../models/': mybasejsondata.json { "addresses": { "type": "addressjsondata.json", "multi": true, "required": true }, . . . } addressjsondata.json { "street_name": "sample", "zip_code": "75024" . . . } this current code comments: import stampit 'stampit'; import * fs 'fs'; // allows me run node's async internal functions generator function runnodefunc( gen, iter) { (iter = gen((err, data) => (err && iter.throw(err)) || iter.next(data))).next(); } // loop through object's keys , values function* objectentries(obj) { let propkeys = reflect.ownkeys(ob...

i have base user model object. each user can either staff member, parent or student. each account type has associated model. for example: class user extends model { public function details() { switch($this->account_type) { case 'staff': return $this->hasone(staff::class); case 'student': return $this->hasone(student::class); case 'parent': return $this->hasone(parentuser::class); } return null; } if run: echo $user->details->staff_code; then outputs crs example. however, if run object_get() : object_get($user, 'details.staff_code'); then outputs null . i figured because in object_get() method, has line: if (! is_object($object) || ! isset($object->{$segment})) i assume because details property magic/dynamic laravel model property, isset() doesn't work on it. whats best way handle this? safe edit object_get() method , r...

i'm using silex's internal forwarding map public urls internal urls i.e. my.domain.com/something serves my.domain.com/something_else using $subrequest = request::create( $redirect, $method, [], // params $request->cookies->all(), $request->files->all(), $request->server->all() ); if ($request->getsession()) { $subrequest->setsession($request->getsession()); } return $app->handle($subrequest, httpkernelinterface::sub_request, true); however, in chrome's inspection tool, appears 301 resulting page, serves result. "by design" represents interesting security problem? there ways around limitation? while can't post code something_else route controller, gist is // controller provider $controller_factory->match('/something_else/{param}', function(...) { include 'path/to/some/file'; }); and // some/file - prepares file downloaded ... return new binaryfileresponse();...
