How to properly validate angular + mongoose fields?

Question

Angular

There is a model

var ArticleSchema = new Schema({
    created: {
        type: Date,
        default: Date.now
    },
    title: {
        ru: [{
                type: String,
                default: '',
                trim: true,
                required: 'Заголовок не может быть пустым'
            }],
        en: [{
                type: String,
                default: '',
                trim: true,
                required: 'Title cannot be blank'
            }]
    },
    content: {
        type: String,
        default: '',
        trim: true
    },
    user: {
        type: Schema.ObjectId,
        ref: 'User'
    }
});

Have a server controller

exports.create = function(req, res) {
  var article = new Article(req.body);
  article.user = req.user;
         console.dir(req.body);

  article.save(function(err) {
    if (err) {
      return res.status(400).send({
        message: errorHandler.getErrorMessage(err)
      });
    } else {
      res.json(article);
    }
  });
};

I have an angular controller

$scope.create = function() {
      var article = new Articles({
        title: this.title,
                                
        content: this.content
      });
      article.$save(function(response) {
        $location.path('articles/' + response._id);

        $scope.title.ru = '';
                                $scope.title.en = '';
        $scope.content = '';
      }, function(errorResponse) {
        $scope.error = errorResponse.data.message;
      });
    };
