Express REST API - Delete Method -

-

i getting stuck on delete method api. application requires user log in , can add courses. courses stored in nested array inside user model. want user able cancel (delete) course view , have course deleted user's profile on server. getting 404 response event though variables comparing identical.

this ajax call delete specific course:

jquery.ajax({     url: "/test/signups/5387c1a0fb06e48f4658170c",      type: "delete",      success: function (data, textstatus, jqxhr) {        console.log("post resposne:");        console.dir(data);        console.log(textstatus);        console.dir(jqxhr);      }   });

this delete method:

app.delete('/test/signups/:id', isloggedin, function(req, res) {     user.findone({'_id': req.user.id }, function(err, user) {         if (err)            return done(err);      if (user) {         var found = false;         var singlesignup = user.signup.filter(function(e){ return e._id == req.params.id })[0]          user.signup.foreach(function (singlesignup, index) {             if (singlesignup._id === req.params.id) {                 found = index;             }         });          if(found) {             user.signup.splice(found, 1);             res.json(200, {status: 'deleted'});         } else {             res.json(404, {status: 'invalid survey question deletion'});         }     }           }); });

the _id values in mongodb not strings, instances of objectid class , don't work correctly == or === operators. it's nuisance. anyway try converting them strings before comparing: singlesignup._id.tostring() === req.params.id. correct in long run, make sure handle cases of null, string or objectid. consider helper library such objectid.

i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
