如何使用Angular Node.js更新MongoDB [英] How to update mongodb with angular nodejs

问题描述

我希望能够使用前端的angularjs和后端的nodejs更新我的mongodb.

My wish is to be able to update my mongodb using angularjs on the front end and nodejs on the backend.

这是我阅读和创建的方式.

Here is how I read and create.

我的angularjs控制器:

My angularjs controller :

myApp.controller('meetupsController', ['$scope', '$resource', 'AuthService', function ($scope, $resource, AuthService) {
  var Meetup = $resource('/api/meetups');
$scope.meetups = []

  Meetup.query(function (results) {
    $scope.meetups = results;
  });

  $scope.createMeetup = function () {
    var meetup = new Meetup();
    meetup.name = $scope.meetupName;
     meetup.text = usersOnline;
    meetup.$save(function (result) {
      $scope.meetups.push(result);
      $scope.meetupName = '';
      $scope.username = '';
    });
  }
}]);

还有我的api:

module.exports.create = function (req, res) {
  var meetup = new Meetup(req.body);
  console.log(req.body);
  meetup.save(function (err, result) {
    console.log(result);
    res.json(result);
  });
}

module.exports.list = function (req, res) {
  Meetup.find({}, function (err, results) {
    res.json(results);
  });
}

任何人都可以帮忙吗?

推荐答案

尝试一下:

    module.exports.update = function (req, res) {
        var id = req.body.id;

      Meetup.findOne({_id: id}, function (err, meetup) {

            meetup.name = req.body.name;

            meetup.save(function (err) {
                if (err) {
                    res.json({
                        success: 0,
                        message: 'unable to update: ' + err.message
                    });
                } else {
                    res.json({
                        success: 1,
                        message: 'updated',
                        data: meetup
                    });
                }
            });

      });
    }

您将通过带有ID和您要更新的其他新值的PUT请求访问此API.

you will hit this API with PUT request with id and other new values you want to update.
