javascript - Meteor 不从 MongoDB 返回数据

Question

由于某种原因，我无法从我的位置集合中获取显示的数据。无论我输入什么，当我在 HTML 中写入 {{myPlaces}} 时，我都会得到 [object Object]。我不应该获得全部内容和列出的所有字段的列表吗？有人可以解释一下吗，因为我从 Meteor.Users 和 Images 获取所有数据。谢谢!

zipCodes.js:

import { Mongo } from 'meteor/mongo';

export const Locations = new Mongo.Collection('locations');

if (Meteor.isServer) {
  Meteor.publish("locations", function () {
   return Locations.find().cursor;
   });
}


if (Meteor.isServer) {

  Locations.batchInsert(
    [
     {
       "country": "NO",
       "zipcode": 1751,
       "place": "Halden",
       "county": "Ostfold",
       "countyNumber": 1,
       "municipality": "Halden",
       "municipalityNumber": 101,
       "lat": 59.1248,
       "long": 11.3875,
       "num": 4
     },
     {
       "country": "NO",
       "zipcode": 1752,
       "place": "Halden",
       "county": "Ostfold",
       "countyNumber": 1,
       "municipality": "Halden",
       "municipalityNumber": 101,
       "lat": 59.1248,
       "long": 11.3875,
       "num": 4
     },

testPage.js

import './testPage.html';
import { Template } from 'meteor/templating';
import Images from '/lib/config/imagesCollection.js';
import { Locations } from '/imports/api/profiles/zipCodes.js';

Template.testPage.helpers({
  // PROFILE INFORMATION
  user: function() {
    return Meteor.users.find();
  },

  // this = {{#each user}} context
  userEmail: function() {
    return this.emails[0].address;
  },

  userFirstName: function() {
    return this.profile.first_name;
  },

  userTitle: function() {
    return this.profile.work_title;
  },

  userMobile: function() {
    return this.profile.mobile;
  },

  userZip: function() {
    return this.profile.zipcode;
  },

  // PATH TO PROFILE PICTURE
  imageLink: function() {
    return Images.findOne({userId: this._id})['_id'];
  },

  // GEODATA TEST
  myPlaces: function() {
    return Locations.find({});
  },
});

您的 myPlaces 帮助程序返回一个光标 - 即一个可让您引用位置列表的函数。您需要使用{{#each }}迭代该光标来显示各个文档。在你的 html 中执行以下操作:

<template name="locations">
  {{#each myPlaces}}
    place: {{place}}
    country: {{country}}
    zipcode: {{zipcode}}
   {{/each}}
</template>
