Question

我将我的代码从Collection转换为SmartCollection :(在second.js中是主要的js文件）

 Testcases = new Meteor.Collection('testcases');
 Backup = new Meteor.Collection('backup');

进入：

Testcases = new Meteor.SmartCollection('testcases');
 Backup = new Meteor.SmartCollection('backup');

切换后应用程序出错：

W2042-21:55:27.312(8)? (STDERR) /Users/dan/Documents/js_app/second/.meteor/local/build/programs/server/boot.js:185
W2042-21:55:27.313(8)? (STDERR) }).run();

我是否需要更新任何内容。鉴于在服务器js代码中，我只实现了2个集合的简单初始化：

 Meteor.publish('testcases', function() {
return Testcases.find({});
});
   Meteor.publish('backup', function() {
      return Backup.find({});
});

“undefined is not a function”错误表示未安装SmartCollection包。

确保您已遵循安装说明，如果是大气包，请确保使用'mrt'而不是'meteor'运行您的应用。

从Collection切换到SmartCollection
