流星:列出服务器上的所有集合 [英] Meteor: List all collections on the server

问题描述

我无法列出服务器上Meteor应用程序中创建的所有集合.

I am unable to list all the collections created within the Meteor app on the server.

收藏集位于... /root/packages/lib/collectionName.js

collectionName的操作成功.但是，由于我有很多集合，因此我需要一个函数来检索创建的集合的所有名称.

Operations to collectionName succeeds. However, as I have many collections, I require a function to retrieve all the names of the collections created.

在服务器功能中 加载完集合后，方法将执行以下功能；

In a server function after the collections have been loaded, a method executes the following function;

MyCollection = Mongo.Collection.getAll();
console.log(MyCollection);


        [ { name: 'users',
       instance: 
          { _makeNewID: [Function],
            _transform: null,
            _connection: [Object],
            _collection: [Object],
            _name: 'users',
            _driver: [Object],
            _restricted: true,
            _insecure: undefined,
            _validators: [Object],
            _prefix: '/users/' },
        options: undefined },
       { name: 'MeteorToys/Impersonate',
         instance: 
         { _makeNewID: [Function],
         ....

Meteor创建的用户集合在那里.但是创建的所有集合(其中3个都带有Collection2程序包)都不会显示.

The user collection created by Meteor is there. But all the collections created, 3 of which are with Collection2 package do not show.

我想念什么?

如果我需要child_process库并执行一系列命令，将会有什么含义.流星mongo" ..."db.getCollectionNames()"?

What are the implications if I require the child_process library and execute a series of commands.. "meteor mongo"... "db.getCollectionNames()"?

推荐答案

要列出服务器上的所有集合，请使用RemoteCollectionDriver访问预先存在的MongoDB集合.要实现此服务器端，您可以遵循以下异步模式:

To list all collections on the server, use the RemoteCollectionDriver to access preexisting MongoDB Collections. To implement this server side, you could follow this asynchronous pattern:

var shell = function () {
    var Future = Npm.require('fibers/future'),
        future = new Future(),
        db = MongoInternals.defaultRemoteCollectionDriver().mongo.db;

    db.collectionNames( 
        function(error, results) {
            if (error) throw new Meteor.Error(500, "failed");
            future.return(results);
        }
    );
    return future.wait();
};
