javascript - meteor 1.3 autoform/quickform 错误

Question

我是 meteor 的新手，刚在 1.3 版发布后到达。由于省略了导入或导出，我一直在努力调试一些非常“愚蠢”的东西，因为大多数教程似乎都没有包含这些内容。因此，以下问题可能属于同一类型。

我想使用包 autoform，所以我刚刚添加了包。(之前也包含了 simple-schema 和 collection2)。

我遇到错误，模板未加载。

这是我的模板

<template name="addItem">

	{{> quickForm collection="Items" id="addItemForm" type="insert" }}

</template>

我有我的 addItem.js

import { Meteor } from 'meteor/meteor';
import { Template } from 'meteor/templating';
import { Mongo } from 'meteor/mongo';

import { Items } from '/imports/collections/itemCollection.js';

import './addItem.html';

Template.addItem.onCreated(function bodyOnCreated(){
	AutoForm.debug();
	Meteor.subscribe('items');
});
   
Template.addItem.helpers({
	Items() {
		return Items.find({});
	},
});

还有我的 itemCollection.js 文件

import { Mongo } from 'meteor/mongo';

export const Items = new Mongo.Collection('items');

Items.allow({
  insert: () => false,
  update: () => false,
  remove: () => false
});

Items.deny({
  insert: () => true,
  update: () => true,
  remove: () => true
});

Items.schema = new SimpleSchema({
	name : {type : String},
	supplier : {type : String},
	Viscosity : {type : Number},
	createdAt : {type : Date()},
	owner : {type: String},
});

Items.attachSchema(Items.schema);

这是我在 chrome 控制台中得到的错误:

有人可以帮助并告诉我我可能做错了什么吗？

Answer 1

您可以通过实现 Meteor 模板帮助器来解决此问题，该帮助器返回集合 Items 而不是游标，就像您现在所做的那样。

例如:

import {Items} from '/itemCollection.js';

Template.addItem.helpers({
    items() {
        return Items;
    }
});

<template name="addItem">
    {{> quickForm collection=items id="addItemForm" type="insert" }}
</template>
