angular controller

function editpostctrl($scope, $http, $location, $routeparams) {     $scope.form = {};     $http.get('/api/posts/details/' + $routeparams.id).         success(function(data) {            $scope.form = data.post;         });      $scope.editpost = function () {         $http.post('/api/posts/edit/' + $routeparams.id, $scope.form).             success(function(data) {                 $location.path('/posts');             });     }; }; 

express app

app.post('/api/posts/edit/:id',api.adminlogincheck,api.editpost); 

api.js

exports.editpost = function (req, res,next) {     console.log("editpost");      var id = req.params.id;     req.body.slug = req.body.title.split(' ').join('-').tolowercase();     delete req.body._id;     mymongodb.update({slug:id},'posts',req.body, function(error,results){         if(error){             console.log(error);             res.json(false);         }else{             res.json(true);         }      }); };
