Question

我正在阅读Discover Meteor一书，在实施了“错误”一章之后，一个拼写错误引起了错误，现在应用程序循环播放，下面是例外情况。

我的问题是，如何解决或重置（我已经尝试'流星重置'，但异常循环仍然存在）

Posts.js

Posts = new Meteor.Collection('posts');

Posts.allow({
    update: ownsDocument,
    remote: ownsDocument
});

Posts.deny({
    update: function( userId, post, fieldNames ) {
        // may only edit the following two fields:
        return (_.without(fieldNames, 'url', 'title').length > 0);
    }
});

    Meteor.methods({
        post: function(postAttributes) {
            var user = Meteor.user(),
                postWithSameLink = Posts.findOne({
                    url: postAttributes.url
                });
            // ensure the user is logged in
            if (!user) throw new Meteor.Error(401, "You need to login to post new stories");
            // ensure the post has a title
            if (!postAttributes.title) throw new Meteor.Error(422, 'Please fill in a headline');
            // check that there are no previous posts with the same link
            if (postAttributes.url && postWithSameLink) {
                throw new Meteor.Error(302,
                    'This link has already been posted', postWithSameLink._id);
            }
            // pick out the whitelisted keys
            var post = _.extend(_.pick(postAttributes, 'url', 'title', 'message'), {
                title: postAttributes.title + (this.isSimulation ? '(client)' : '(server)'),

              Meteor.setTimeout( function() {
                future.return();
              }, 5*1000);
              future.wait();
            }
            var postId = Posts.insert(post);
            return postId;
        }
    });

您的代码中存在拼写错误。

Posts.allow({
    update: ownsDocument,
    remote: ownsDocument
});

应更改为

Posts.allow({
    update: ownsDocument,
    remove: ownsDocument
});

循环期货例外。如何解决问题
