Question

我正在使用 Meteor 1.6 ，并尝试使用下面的aldeed的quickForm更新集合。

收藏：

import { Mongo } from 'meteor/mongo';
import SimpleSchema from 'simpl-schema';
SimpleSchema.extendOptions(['autoform']);

export const Settings = new Mongo.Collection('Settings');

SettingsSchema = new SimpleSchema({
    "userId": {
        type: String,
        label: "User ID",
    },
    "speed": {
        type: Number,
        label: "Speed",
    },
    "fuelLevel": {
        type: Number,
        label: "Fuel Level",
    },
    "fuelCapacity": {
        type: Number,
        label: "Fuel Capacity",
    },
    "temperature": {
        type: Number,
        label: "Temperature",
    },
}, { tracker: Tracker });

Settings.attachSchema(SettingsSchema);

UI.js

import './ManageAlerts.html';
import '../../../components/common/staggering/Staggering';
import { Settings } from '/imports/api/users/settings';

window.Settings = Settings;

Template.ManageAlerts.onCreated(function () {
    console.log('Landed on page');
    this.subscribe('Settings.Individual');
});

Template.ManageAlerts.helpers({
    settings() {
        return Settings.find({ userId: Meteor.userId() });
    },
    Settings() {
        return Settings;
    }
});

UI.html

<template name="ManageAlerts">
    <div class="content">
        <div class="row">
            {{#each settings}} {{> quickForm collection="Settings" id=_id type="update" doc=this}} {{/each}}
        </div> 
    </div>
</template>

错误：

任何帮助将不胜感激。

未定义您的收藏集时，会发生此错误。

一种可能的解决方法是像这样使集合成为全局的：

#unignore gz files 
!*.gz

否则，您可以更改模板将集合返回表单的方式：

global.Settings = Settings; // try this instead of window

现在，因为您已经定义了此帮助器，所以它使用了一个帮助器来显式接收该集合，而不是查看全局范围：

{{> quickForm collection=Settings id=_id type="update" doc=this}}

如果这仍然不起作用，还请检查给定路径是否正确导入了集合（例如，尝试不以Settings() { return Settings; }开头，而是相对于当前目录）。
