Meteor：RangeError：超出最大调用堆栈大小 [英] Meteor: RangeError: Maximum call stack size exceeded

问题描述

我收到以下错误

W20141210-18:14:54.394(5.5)? (STDERR) 
W20141210-18:14:54.395(5.5)? (STDERR) /Users/removed/.meteor/packages/meteor-tool/.1.0.36.1phxfod++os.osx.x86_64+web.browser+web.cordova/meteor-tool-os.osx.x86_64/dev_bundle/lib/node_modules/fibers/future.js:173

当我使用meteor方法返回查询结果时。

When I am using meteor methods to return a query result.

Meteor.methods({
    rquery: function(post){
        console.log(post);
        var result = AdvtColl.find();
        return result;
    }
});

推荐答案

您无法从方法返回游标 - 只有 EJSON 。在你的代码中，结果是一个 find 调用的结果，这是一个游标 - 你需要使用 findOne 或在 find（）之后添加 fetch（）返回有问题的文件。

You can't return a cursor from a method - only EJSON. In your code, result is the result of a find call, which is a cursor - you need to either use findOne or add fetch() after the find() to return the document(s) in question.

var result = AdvtColl.findOne(); // RETURNS A DOCUMENT

var result = AdvtColl.find().fetch(); // RETURNS AN ARRAY OF DOCS (EVEN IF THERE'S ONLY ONE OF THEM)
