快速渲染路径上的流星错误TypeError:dynamics.slice不是函数

Question

每次页面呈现时,我都会收到以下错误.我以前没有收到这些,他们刚开始有一天,我发现的唯一解决方案是卸载快速渲染.以任何方式改变路线似乎没有任何影响.知道问题的根源是什么吗？

我发现以下页面描述了类似的错误,但我在waitOn函数中没有this.redirect(...)或Router.go(...):https: //github.com/kadirahq/fast -render#3- waiton和-订阅的方法

以下是帐户路由和相应控制器的代码:

Router.route("/account", {
    name: "Account",
    controller: simpleWebsiteController,
    waitOn: function () {
        return [
            Meteor.subscribe("userData"),
            Meteor.subscribe("userMessages")
        ]
    },
    data: function () {
        var messages = Collections.Messages.find({userId: Meteor.userId()},{sort: { creationDate: -1 }});
        var posts = Collections.Posts.find({});
        var comments = Collections.Comments.find({});
        return {
            content: "page-account",
            userMessages: messages,
            userComments: comments,
            userPosts: posts
        };
    },
    onBeforeAction: function () {
        // If the user is not logged in, redirect to login page
        var path = this.location.get().path;
        if (!Meteor.userId() && path.indexOf("/login") != 0)
            this.location.go("/login");
        else
            this.next();
    }
});

控制器:

var simpleWebsiteController = RouteController.extend({
    layoutTemplate: "MainLayout",
    waitOn: function () {
        return [
            Meteor.subscribe("userData"),
            Meteor.subscribe("categoriesList"),
            Meteor.subscribe("cityData")
        ]
    },
    onBeforeAction: function () {
        // If the user is not logged in, redirect to login page
        var path = this.location.get().path;
        if (!Meteor.userId() && path.indexOf("/login") != 0)
            this.location.go("/login");
        else
            this.next();
    },
    onAfterAction: function() {
      $('.row-offcanvas').removeClass('active');
      $('.collapse').removeClass('active');
    },
    fastRender: true
});

有关此错误原因的详细信息,请查看此答案.

不幸的是,流程路由器作为依赖项的快速渲染包正在搞乱流星内部,并且当流星的核心代码得到更新时会破坏你的代码.

您可以克隆和编辑kadira的快速渲染并修复此问题.

转到项目目录下的packages文件夹

cd your_project_dir/packages/

git clone https://github.com/kadirahq/fast-render.git

然后,在第23行编辑your_project_dir/packages/fast-render/lib/server/context.js:

// support for Meteor.user
// Fibers.current._meteor_dynamics = {};
Fibers.current._meteor_dynamics = []; // <-- Fixed

现在这将覆盖kadira的v2.16.0快速渲染包.
