当我在流星中使用post_edit方法时，我得到未定义的参数。如何更新流星集合？

Question

//My collection
import { Mongo } from 'meteor/mongo';
import PostSchema from './schema';

const Posts = new Mongo.Collection('Posts');

Posts.attachSchema(PostSchema);

export default Posts;

//My schema
import SimpleSchema from "simpl-schema";

export default new SimpleSchema({
    title: {
        type: String
    },
    description: {
        type: String
    },
    createdAt: {
        type: Date,
        autoValue: function() {
            if (this.isInsert) {
                return new Date();
            } else if (this.isUpsert) {
                return {$setOnInsert: new Date()};
            } else {
                this.unset();  // Prevent user from supplying their own value
            }
        }
    },
    userId: {
        type: String,
        autoValue: function(){ return this.userId }
    }
});    

//My methods file

     import {Meteor} from "meteor/meteor";
        import Posts from "/imports/api/posts/collection";
        import Security from '/imports/api/security.js';

        Meteor.methods({

            'post_create' (data) {
                if (!data) {
                    throw new Meteor.Error('error', 'Make sure you have filled all the fields! ;)', 'Some details');
                } else if (Security.checkLoggedIn(this.userId)) {
                    console.log("Are you sure you logged in?");
                } else {
                    return Posts.insert(data);
                }

            },
            'post_get': function (id) {
                   if (Security.checkLoggedIn(this.userId)) {
                    console.log("Are you sure you logged in?");
                } else {
                    return Posts.find({id}).fetch();
                }
            },

            'post_remove': function (id) {
                if (Security.checkLoggedIn(this.userId)) {
                    console.log("Are you sure you logged in?");
                } else {
                    return Posts.remove({_id: id});
                }
            },

    //My problem is here! When I call this method in the postEdit.jsx file i get title prop undefined
            'post_edit': function (data) {

                if (Security.checkLoggedIn(this.userId)) {
                    console.log("Are you sure you logged in?");
                } else {
                    Posts.update(data,{
                        $set: {
                            title: this.data.title,
                            description: data.description
                        }
                    });
                }enter code here
            }
        });

//我正在努力了解如何解决这个问题。我知道问题出在参数上，并且它们是未定义的....但我不知道如何为密钥赋予正确的值。任何提示/链接/建议都是高度赞成的。
