流星1.4 Aldeed Collection2未开箱即用

问题描述：

我刚刚创建了一个新项目。流星1.4 Aldeed Collection2未开箱即用

这是我加入到我的项目包：

aldeed:[email protected] 
aldeed:autoform

我还安装了NPM包，meteor npm install --save simpl-schema。

我创建了一个/lib文件夹。

在这里面，我创建了一个common.js文件与此代码：

var Books = new Mongo.Collection("books"); 

var Schemas = {}; 

Schemas.Book = new SimpleSchema({ 
    title: { 
     type: String, 
     label: "Title", 
     max: 200 
    }, 
    author: { 
     type: String, 
     label: "Author" 
    }, 
    copies: { 
     type: SimpleSchema.Integer, 
     label: "Number of copies", 
     min: 0 
    }, 
    lastCheckedOut: { 
     type: Date, 
     label: "Last date this book was checked out", 
     optional: true 
    }, 
    summary: { 
     type: String, 
     label: "Brief summary", 
     optional: true, 
     max: 1000 
    } 
}); 

Books.attachSchema(Schemas.Book);

当我重新启动应用程序，它崩溃，扔我：

任何想法有什么不对？

出于好奇，为什么安装collection2通过流星添加，但通过npm简单模式？ collection2自动添加简单模式。那么[collection2-core]（https://atmospherejs.com/aldeed/collection2-core）你有没有'npm install' [这个简单模式]（https://www.npmjs.com/package/simple-schema ）？ –

@MichelFloyd我通过'npm'按照Aldeed自己安装'collection2-core @ 2.0.0'的指示安装它。我也'npm install'简单模式，但是同样的错误出现。 – Neonjack

你从哪里找到这些说明？没有提及npm [这里]（https://atmospherejs.com/aldeed/collection2-core） –

答

试试这个....

var Books = new Mongo.Collection("books"); 

Books.schema = new SimpleSchema({ 
    title: { 
     type: String, 
     label: "Title", 
     max: 200 
    }, 
    author: { 
     type: String, 
     label: "Author" 
    }, 
    copies: { 
     type: SimpleSchema.Integer, 
     label: "Number of copies", 
     min: 0 
    }, 
    lastCheckedOut: { 
     type: Date, 
     label: "Last date this book was checked out", 
     optional: true 
    }, 
    summary: { 
     type: String, 
     label: "Brief summary", 
     optional: true, 
     max: 1000 
    } 
}); 

Books.attachSchema(Books.schema);

另外，您还可以将模式为：从NPM包SIMPL型模式使用时

const Books = new Mongo.Collection("books"); 
Books.attachSchema(new SimpleSchema({ 
    title: { 
    type: String, 
    label: "Title", 
    max: 200 
    }, 
    ... 
}));

答

SimpleSchema不被视为一个全局变量。你必须确保：

import SimpleSchema from 'simpl-schema';
