需要帮助更新 Router.js 以升级到 Meteor 1.0 和 iron:router 软件包

Question

我正在从 Meteor 8.2 更新到 Meteor 1.0。我已经删除了所有旧的 meteorite 包并安装了相关的 meteor package 系统包。我必须安装新的 iron-router 包，并且在 meteor run 的控制台中出现以下错误：

Route dispatch never rendered. Did you forget to call this.next() in an onBeforeAction?

包的迁移说明说："onBeforeAction hooks now require you to call this.next(), and no longer take a pause() argument."

我尝试按照示例从函数中删除 pause 并在 else 语句后添加 this.next();，但无济于事。

如何编辑我的路由器以便它使用新的 onBeforeAction 挂钩？此外，您可以从迁移中调用的任何其他可能有问题的内容都将不胜感激。谢谢！

这是我的路由器文件：

新的 onBeforeAction 钩子必须调用 this.next();您必须在每个 onBeforeAction 中调用它。例如，您在新 Iron Router 中的管理路由将如下所示：

Router.route('/admin', {
    name: 'adminView',
    onBeforeAction: function () {
        var user = Meteor.user();
        if (!user || !user.admin) {
            this.render('home');
        }
        this.next();
    }
});

将 Router.map 中的所有 this.route(...) 替换为 Router.route('/path', options) 并删除 Router.map()

您的全局 onBeforeAction 将如下所示：

Router.onBeforeAction(function() {
  Alerts.clearSeen();
  this.next();
});

此外，您不需要将路线包装在 Meteor.startup(...) 中。你可以删除它。

并且没有暂停参数了，而不是暂停调用 this.next() 外部条件：

var filters = {
    nProgressHook: function () {
        // we're done waiting on all subs
        if (this.ready()) {
            NProgress.done();
        } else {
            NProgress.start();
        }
        this.next();
    }
};

Router.onBeforeAction(filters.nProgressHook);
