我正在尝试上传图像并使用下面的代码更新数据库集合中的图像的URL.

Controller.prototype.handle = function (req, res, next) {
  var id = req.params.id,
      controller = req.params.controller,
      optionalController;

  optionalController = _.clone(controller);

  // handle optional controller
  if (controller === 'newboat') {
    controller = 'boat';
  } else if (controller === 'newcrew') {
    controller = 'crew';
  }

  var files = req.files.files || {},
      monthYear = new Date(),          
      monthYear = [monthYear.getFullYear(), monthYear.getMonth()],      
      filename = files[0].originalFilename,
      path = files[0].path,
      extension = filename.match(EXPRESSION_EXTENSION)[1],
      destFolder = [ROOT, monthYear[0], '/', monthYear[1] ].join(''),
      destination = [ROOT, monthYear[0], '/', monthYear[1] ,'/', id, …

我一直使用summernote作为我的默认文本编辑器,但是在初始化时我默认无法设置特定的字体大小.

到目前为止我试过了

$('.active-textcontainer').summernote({
        toolbar: [
            ['style', ['bold', 'italic', 'underline']],
            ['fontsize', ['fontsize']],
            ['color', ['color']],
            ['para', ['ul', 'ol', 'paragraph']]
        ],
         height:150,
         fontsize:'18px'
    });

和

$('.active-textcontainer').summernote({
        toolbar: [
            ['style', ['bold', 'italic', 'underline']],
            ['fontsize', ['fontsize']],
            ['color', ['color']],
            ['para', ['ul', 'ol', 'paragraph']]
        ],
         height:150,
         fontsize:'18'
    });

蚂蚁帮助将不胜感激.

我想利用promises功能,我可以同步连接到mongodb,我可以通过将连接传递给不同的模块来重用连接.

这是我想出来的东西

class MongoDB {

    constructor(db,collection) {      
      this.collection = db.collection(collection);
    }

    find(query, projection) {
        if(projection)
            return this.collection.find(query, projection);
        else
            return this.collection.find(query);
    }
}

class Crew extends MongoDB {

    constructor(db) {        
        super(db,'crews');
    }

    validate() {

    }
}

我想在我的初始代码中的某个位置设置一个连接,如下面的那个,然后重用不同类的连接,就像mongoose或monk那样,但只使用node-mongodb-native包.

MongoClient.connect(url)
          .then( (err,dbase) => {
                global.DB = dbase;
              });


var Crew = new CrewModel(global.DB);


Crew.find({})
   .then(function(resp) {
      console.log(resp);
   });

现在,db在主MongoDB类中返回undefined,并且无法通过谷歌或文档调试这个.

编辑:我曾假设承诺是同步的但事实并非如此.

我是新来表达的,我很惊讶我应该如何访问前端的数据,

我有以下代码

exports.init = function(req, res){
  if (req.isAuthenticated()) {
    //res.send();  
    var userId = req.user._id  
    res.render('account/usernotes');
  }
  else {
    res.render('signup/index', {
      oauthMessage: '',
      oauthTwitter: !!req.app.config.oauth.twitter.key,      
      oauthFacebook: !!req.app.config.oauth.facebook.key,
      oauthGoogle: !!req.app.config.oauth.google.key
    });
  }
};

我想将UserId发送到视图,以便我可以访问它,以便我可以使用它获取数据,但到目前为止使用send(); 将数据的值呈现给前端,因此如何访问它.我猜

res.render('account/usernotes',req.user._id);

应该工作,但如何在此之后访问数据？

即使我提供了所有字段,我在保存到数据库时收到以下消息的验证错误,

{ [ValidationError: Validation failed]
  message: 'Validation failed',
  name: 'ValidationError',
  errors: 
   { Name: 
      { [ValidatorError: Path `Name` is required.]
        message: 'Path `Name` is required.',
        name: 'ValidatorError',
        path: 'Name',
        type: 'required',
        value: undefined } } }

这就是我想要保存的对象的样子

    { Name: 'Nobody Singh',
  phone: '+919177121364',
  address: 'flat no 306 koratala apartments\nstreet no 3 ,Himayatnagar, Near Siraj plaza',
  start: '2014-12-03T13:00:00.000Z',
  end: '2014-12-03T15:00:00.000Z',
  details: 'flat no 306 koratala apartments\nstreet no 3 ,Himayatnagar, Near Siraj plaza' }

这是架构

    // load the things we need
var mongoose …

我想在vuejs项目中使用bootstrap select插件,我对如何将它作为指令合并到我的项目中感到困惑.在查看vuejs网站中的select2示例后,我想出了以下内容.

<span id="el">
  <select class="selectpicker" data-style="btn-primary" v-selectpicker="selected" :options="workflow">
    <option value="0">default</option>
  </select>                                                    
</span>

这是我的指示和观点

require("bootstrap-select");

Vue.directive('selectpicker',{  

    twoWay: true,

    deep: true,

    bind: function() {          
        $(this.el).selectpicker().on("change", function(e) {
            this.set($(this.el).val());
        }.bind(this));
    },
    update: function (value) {
        $(this.el).selectpicker('refresh').trigger("change");
    },
    unbind: function () {
        $(this.el).off().selectpicker('destroy');
    }
});


new Vue({

    el: '#el',

    data: {

        tasksLoaded: false,
        tasks: [],
        workflow: [
            {
                id:'todo',
                value: 'To Do'
            }, 
            {
                id: 'backlog', 
                value: 'Backlog'
            },
            {
                id: 'doing', 
                value: 'Doing'
            },
            {
                id: 'restest', 
                value:'Retest'
            },
            {
                id: 'completed', …

我有一个JSON对象,我想创建一个使用mongoose的模式

    { ProjectName: 'asdf',
  Embargo: 'Yes',
  Angle: '1',
  Facts: '[{"count":1,"fact":"dsafdsaf","content":"dsafdsaf"}, {"count":3,"fact":"dsafdsaf","content":"dsafdsaf" } , {"count":2,"fact":"dsafdsaf","content":"dsafdsaf"}]',
  About: '<p>Anthony Bodin&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</p>',
  EditorNote: 'No',
  OrderId: 'tok_14kGRO2Jju1nvjb47YF9jQTJ',
  Payment: 'Paid' }

我的问题是Facts元素将包含对象数组,我不太确定如何将它保存到数据库中,因为这是我现在拥有的模式

var ArticleSchema = new mongoose.Schema({
    userId: {
        type: String,
        default: ''
    },
    userEmail: {
        type: String,
        default: ''
    },
    article: {
        date: {
            type: Date,
            default: Date()
        },
        ProjectName: {
            type: String,
            default: ''
        },
        Embargo: {
            type: String,
            default: true
        },
        Angle: {
            type: String,
            default: ''
        },
        Facts: {                
            type:Array
        },
        About: { …

我在SpyOn方法上得到一个未定义的错误

这就是我想出的

    'use strict';
describe('WebApp: AccountController', function() {
  return beforeEach(function() {
    module('webApp');
    module('tpls');
    return inject(function($injector) {
      this.q = $injector.get('$q');
      this.userMock = {
        id: 1,
        email: 'pidsafs@gmail.com',
        name: 'Adones Pitogo'
      };
      this.modalMock = {
        open: (function(_this) {
          return function(tpl, ctrl) {
            _this.def = _this.q.defer();
            _this.def.resolve(true);
            return {
              result: _this.def.promise
            };
          };
        })(this)
      };
      this.teamMock = {
        id: 1
      };
      this.repoMock = {
        id: 1
      };
      this.httpBackend = $injector.get('$httpBackend');
      this.httpBackend.whenGET('/api/v1/session').respond({
        status: 'ok',
        user: this.userMock
      });
      this.httpBackend.whenGET("/api/v1/users/" + this.userMock.id + "/teams").respond({
        status: 'ok', …

我是JSON的新手,我使用json_encode创建一个看起来像这样的JSON对象

[{
      "timestamp": "12\/16\/2013 0:00",
      "curr_property": "7211",
      "curr_property_cost": "123",

我有一个格式不正确的JSON响应，其中包含特殊字符，我想通过使用string.replace（）删除特殊字符来清理它。由于某种原因，它不起作用。

这是JSON结果

[{"User::newPassword":["Password could not be changed. The request can't be validated"]},[]]

这是我的表情。

resp.replace(::g, '');

但这似乎不起作用。任何对此的建议将不胜感激，因为后端我对此无能为力。

我对我在代码中做错了什么感到有些困惑
