Meteor.js - 不会显示订阅数据，只显示游标对象

Why isn't it displaying a file record in my template? The only thing it returns to the template is just the 'cursor' object.

为什么不在我的模板中显示文件记录?它返回模板的唯一方法就是'光标'对象。

What the console.log(file) output is in the JS console:

console.log(文件)输出在JS控制台中的内容:

 FilesCollection {collectionName: "Files", downloadRoute: "/cdn/storage", schema: Object, chunkSize: 524288, namingFunction: false…}

I've looked at every post, etc. I realize it returns a cursor to the client, but I'm doing a Files.findOne() query, which should return the record itself to the template / html.

我查看了每个帖子等等。我意识到它会将光标返回给客户端,但我正在做一个Files.findOne()查询,它应该将记录本身返回给模板/ html。

import { Meteor } from 'meteor/meteor';
import { Mongo } from 'meteor/mongo';

export const Files = new FilesCollection({
   collectionName: 'Files',
   allowClientCode: false, // Disallow remove files from Client
   onBeforeUpload: function (file) {
   // Allow upload files under 10MB, and only in png/jpg/jpeg formats
   if (file.size <= 10485760 && /png|jpg|jpeg/i.test(file.extension)) {
     return true;
   } else {
     return 'Please upload image, with size equal or less than 10MB';
   }
  }
});


if (Meteor.isServer) {
  // This code only runs on the server
  Meteor.publish('getFile', function(id) {
  return Files.find({_id: id }).cursor;
});
}

      self.subscribe('getFile', fileId);
    });

    return file;

World's dumbest mistake, remember: template names in Meteor must be in Upper case!

世界上最愚蠢的错误,记住:Meteor中的模板名称必须是大写的!
