流星1.3 autoform/quickform错误

Question

我是流星新手，刚刚在发布1.3后到货。 由于大多数教程似乎没有包含这些内容，所以我一直在努力去调试一些非常“愚蠢”的东西，因为省略了导入或导出。 所以下面的问题可能是相同的类型。

我想使用包autoform，所以我刚刚添加了包。 （简单模式和collection2也被包括在内）。

我收到错误并且模板无法加载。

这里是我的模板

<template name="addItem"> 
 

 
\t {{> 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(){ 
 
\t AutoForm.debug(); 
 
\t Meteor.subscribe('items'); 
 
}); 
 
    
 
Template.addItem.helpers({ 
 
\t Items() { 
 
\t \t return Items.find({}); 
 
\t }, 
 
});

而且我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({ 
 
\t name : {type : String}, 
 
\t supplier : {type : String}, 
 
\t Viscosity : {type : Number}, 
 
\t createdAt : {type : Date()}, 
 
\t owner : {type: String}, 
 
}); 
 

 
Items.attachSchema(Items.schema);

这是我在Chrome控制台出现错误：

有人可以帮助，告诉我，我可能是做错了？

Answer 1

你可以通过实现一个Meteor模板助手来解决这个问题，该助手返回集合Items而不是一个游标，就像你现在所做的那样。

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

尝试导入文件本身而不是{Items}。我认为问题是，您只导入集合，但其附件未被导入。尝试

import'imports/collections/itemCollections.js';

而且，您不需要插入类型的辅助函数，它的更新。

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); 
}); 

那么做到这一点：

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

Answer 4

我的集合称为服务。

/imports/startup/client/index.js

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

window.Services = Services; 

/client/main.js

import '/imports/startup/client';
