javascript - meteorjs用户权限未与服务器同步

Question

我是meteorjs 和 MongoDB 的新手。 我在 Win 7 上运行 Meteor，并关注 isaac strack 的“Meteor.js JavaScript 框架入门”，但我停留在第 6 章“授予管理员权限” 我正在关注他的代码，但似乎当管理员登录时，我将一个项目添加到列表中，该项目显示为秒的分割，可能是因为本地缓存和服务器同步 但我在这里做错了什么？ 我的代码: 客户端:

Meteor.subscribe('Categories');

Meteor.autosubscribe(function() {
    Meteor.subscribe("listdetails",
        Session.get('current_list'));
});

Template.categories.lists = function () {
    return lists.find({},{sort: {Category: 1}});
};

Session.set('adding_category', false);

Template.categories.new_cat = function () {
    return Session.equals('adding_category',true);
};
Template.categories.events({

    'click #btnNewCat': function (e, t) {

        Session.set('adding_category', true);

        Meteor.flush();
        focusText(t.find("#add-category"));
    },

    'keyup #add-category': function (e,t){
        if (e.which === 13)
        {
            var catVal = String(e.target.value || "");
            if (catVal)
            {
                lists.insert({Category:catVal,owner:this.userId});
                Session.set('adding_category', false);
            }
        }
    },
    'focusout #add-category': function(e,t){

        Session.set('adding_category',false);

    },
    'click .category': selectCategory
});

/////Generic Helper Functions/////

    i.focus();
    i.value = val ? val : "";

    {

        {
            if (l.items[i].Name === item_name)
            {
                l.items[i].LentTo = lendee_name;
            }
        }
        lists.update({"_id":list_id},{$set:{"items":l.items}});
    }

                    "label-important" : "label-success";
            }
            return cats.items;
        }
    }
};// < ---- ending bracket for Template.list.items function ----

Template.list.list_selected = function() {

Template.categories.list_status = function(){

            Session.set('lendee_input',null);
        }
        if (e.which === 27)
        {
            Session.set('lendee_input',null);
        }
    }
});

Accounts.ui.config({
    passwordSignupFields: 'USERNAME_AND_OPTIONAL_EMAIL'
});

服务器端:

Meteor.startup(function () {
    Meteor.publish("Categories", function() {
        return lists.find({owner:this.userId},{fields:{Category:1}});
    });
    Meteor.publish("listdetails", function(category_id){
        return lists.find({_id:category_id});
    });
});

两者:

function adminUser(userId) {
     var adminUser = Meteor.users.findOne({username:"admin"});
     return (userId && adminUser && userId === adminUser._id);
 }
 lists.allow({
     insert: function(userId, doc){
         return (adminUser(userId) || (userId && doc.owner === userId));
     },
     update: function(userId, docs, fields, modifier){
         return adminUser(userId) || _.all(docs, function(doc) {
             return doc.owner === userId;
         });
     },
     remove: function (userId, docs){
         return adminUser(userId) || _.all(docs, function(doc) {
             return doc.owner === userId;
         });
     }
 });

Answer 1

经过大量调试尝试和失败后，我解决了问题，问题出在服务器端，这是原始代码:

Meteor.startup(function () {
    Meteor.publish("Categories", function() {
        return lists.find({owner:this.userId},{fields:{Category:1}});
    });
    Meteor.publish("listdetails", function(category_id){
        return lists.find({_id:category_id});
    });
});

这是固定代码:

Meteor.startup(function () {
    Meteor.publish("Categories", function() {
        return lists.find({owner:Meteor.userId},{fields:{Category:1}});
    });
    Meteor.publish("listdetails", function(category_id){
        return lists.find({_id:category_id});
    });
});

注意:更改是在第 3 行完成的，而不是owner:this.userId - 不存在，我将其替换为 Meteor.userId
