如何使用nodejs在mongodb中保存json数组

Question

我尝试使用nodejs创建一个新的mongodb文档，这里是我的架构

var resumeSchema = mongoose.Schema(
{   
    user:{type: mongoose.Schema.Types.ObjectId, ref: 'User'},
    education:[
        {
            name:{type: String, required: true},
            qualification:{type: String, required: true},
            startEnd:{type: String, required: true},
            note:{type: String, required: true}
        }
    ],
    experience:[
        {
            employer:{type: String, required: true},
            jobTitle:{type: String, required: true},
            startEnd:{type: String, required: true},
            note:{type: String, required: true}
        }
    ]
 }
)
var Resume = mongoose.model('Resume', resumeSchema);

这是我的nodejs route

router.post('/add-resume', function(req, res, next) {
     var newResume = new Resume();
        newResume.user = req.user._id;
        newResume.education= req.body.educations;
        newResume.experience = req.body.experiences;

      newResume.save(function(err, resume){
          if (err) { 
            return next(err); 
          }else{
             console.log(resume);
        }
    });
 });
});

req.body.educations和req.body.experiences是json数组。

我需要有关如何解决此问题的帮助

我在客户端使用角度js，发送到服务器的数据是formData。这是我的客户代码

 angular
.module('app')
.directive('fileModel', ['$parse', function ($parse) {
    return {
       restrict: 'A',
       link: function(scope, element, attrs) {
          var model = $parse(attrs.fileModel);
          var modelSetter = model.assign;
          element.bind('change', function(){
             scope.$apply(function(){
                modelSetter(scope, element[0].files[0]);
             });
          });
       }
    };
 }]);

 angular
 .module('app')
 .controller('addresumeCtrl', addresumeCtrl);

 function addresumeCtrl ($scope,ngDialog,$http) {

 $scope.resume = {};
 $scope.educations = [];
 $scope.experiences = [];

 $scope.resume.educations = $scope.educations;
 $scope.resume.experiences = $scope.experiences;
 $scope.addNewEducation = function() {
    $scope.educations.push({});
 };

$scope.addNewExperience = function() {
   $scope.experiences.push({});
};

$scope.removeEducation = function(index) {
  $scope.educations.splice(index, 1);
};

$scope.removeExperience = function(index) {
  $scope.experiences.splice(index, 1);
};

$scope.create = function(){
 var uploadUrl = "/user/add-resume";
 var fd = new FormData();
 for(var key in $scope.resume)
    fd.append(key, $scope.resume[key]);
 $http.post(uploadUrl, fd, {
    transformRequest: angular.identity,
    headers: {'Content-Type': undefined}
  }).then(function (response) {

 }, function (error) {

});

};

}

这是html

 <form>

  <!-- Education -->
  <div class="form with-line">
    <h5>Education <span>(optional)</span></h5>
    <div class="form-inside">

      <!-- Add Education -->
      <div data-ng-repeat="education in educations" class="form boxed education-box">
        <a href="" ng-click="removeEducation(educations.indexOf(education))" class="close-form  button"><i class="fa fa-close"></i></a>

      </div>

      <a href="#" class="button gray"  ng-click="addNewExperience()"><i class="fa fa-plus-circle"></i> Add Experience</a>

    </div>
  </div>


  <div class="divider margin-top-0 padding-reset"></div>
  <a href="" ng-click="create()" class="button big margin-top-5">Preview <i class="fa fa-arrow-circle-right"></i></a>
