Question

我是流星的新手，刚刚发布1.3版本。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它。因此，以下问题可能属于同一类型。

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

我收到错误，模板无法加载。

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({});
	},
});

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);

以下是我在Chrome控制台中遇到的错误：

有人可以帮忙并告诉我我可能做错了什么？

Answer 1

您可以通过实现Meteor模板帮助程序来解决此问题，该帮助程序返回集合Items而不是光标，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>

Answer 2

尝试仅导入文件本身而不是{Items}。我认为问题是，您只导入集合，但未导入其附件。试试

import'import / collections / itemCollections.js';

并且，您不需要插入类型的辅助函数，它用于更新。

Answer 3

尝试添加dburles:mongo-collection-helpers并执行以下操作。

import {Mongo} from "meteor/mongo";
import {Template} from "meteor/templating";

Template.registerHelper('collection', function (name) {
  return Mongo.Collection.get(name);
});

然后这样做：

+autoform(
  id="some-form"
  collection=(collection 'items')
)

Answer 4

我的收藏称为服务。

<强> /imports/startup/client/index.js

import { Services } from '/imports/api/services/services.js';

window.Services = Services;

<强> /client/main.js

import '/imports/startup/client';
