Mongoose TypeError:不能使用"in"运算符在其中搜索"_id" [英] Mongoose TypeError: Cannot use 'in' operator to search for '_id' in

问题描述

我有一个Rails开发人员尝试使用骨干，并使用Backbone.js应用程序书-我的第一个Backbone/Node/Mongo应用程序，请保持柔和.

I've a rails developer trying my hand at backbone and using the Backbone.js application book - my first Backbone / Node / Mongo app so be gentle.

我已经回答了类似的问题，并且已经被困了12个小时，所以我认为是时候丢下毛巾了.错误在上方和下方

I've poured over the similar questions and have been stuck for 12 hours now so I think it's time to throw in the towel. error is above and below

[TypeError: Cannot use 'in' operator to search for '_id' in YES PLEASE]

我正在尝试将Book保存到图书馆，这是我的模式.

I'm trying to save a Book to the library, here is my schema.

var Keywords = new mongoose.Schema({
    keyword: String
});

var Book = new mongoose.Schema({
    title: String,
    author: String,
    releaseDate: Date,
    keywords: [ Keywords ]
});

当我做一个简单的Ajax帖子时，将显示并保存关键字，但是当我尝试从视图中添加它们时，它们将失败.这是library.js视图.

When I do a simple Ajax post, the Keywords get displayed and saved, but when I try to add them from the view, they fail. Here is the library.js view.

var app = app || {};

app.LibraryView = Backbone.View.extend({
  el: "#books",

  events: {
    'click #add': "addBook"
  },

  initialize: function() {
    this.collection = new app.Library();
    this.collection.fetch({reset: true});
    this.render();

    this.listenTo(this.collection, 'add', this.renderBook );
    this.listenTo(this.collection, 'reset', this.render)
  },

  render: function() {
    this.collection.each(function(item) {
      this.renderBook(item);
    }, this);
  },

  renderBook: function(item) {
    var bookView = new app.BookView({
      model: item
    });
    this.$el.append(bookView.render().el );
  },

  addBook: function(e) {
    e.preventDefault();
    var formData = {};

    $('#addBook div').children('input').each(function( i,el ) {
      if( $( el ).val() != '' )
      {
        if( el.id ==="kewords" ) {
          _.each( $(el).val().split(' '), function( keyword ){
            formData[ el.id ].push({ 'keyword': keyword });
          });
        } else if ( el.id ==='releaseDate' ){
          formData[ el.id ] = $("#releaseDate").datepicker('getDate').getTime();
        } else {
          formData[ el.id ] = $( el ).val();
        }
      }
      $( el ).val('')
    });

    this.collection.create( formData );
  }
});

任何帮助都是最欢迎的.另外，调试JavaScript的最佳做法是什么?进入控制台并向下钻取?是否有更好的调试器库可用于节点?

Any help would be most welcome. Also, what are best practices for debugging javascript? Going into the console and drilling down? Is there a better debugger library to use with node?

谢谢

我猜您的发布数据JSON对象属性错误.更正后，我遇到了同样的问题，问题消失了.

I guess your post data JSON objects properties is wrong. I faced same problem after my correction, the issue is gone.

问题状态:

  {"userId": "58821f9b1b059b515a53d44b","dashboard":"mobile_dashboard"}

更正后:

{"userId": "58821f9b1b059b515a53d44b","dashboard":{"title":"mobile_dashboard","viewData":{"className":"BuilderDroppableZone"}}}
