Meteor v 1.0 和 Iron:Router [英] Meteor v 1.0 and Iron:Router

问题描述

自从将 Meteor 升级到 1.0 版后，还有其他人从 Iron-Router 收到以下错误吗?

如果您知道如何解决此问题，请在此处发布.

<块引用>

路由调度从未呈现.您是否忘记在 onBeforeAction 中调用 this.next() ?

Router.map(function () {Router.route('profileShow', {等待:函数(){如果(流星.用户()){Meteor.subscribe('userData');} 别的 {this.next();}},数据:函数(){如果(流星.用户()){返回 {profile: Meteor.user().profile};}}});});

解决方案

在最新版本的 Iron Router 中有一个非向后兼容的变化.迁移指南说:

<块引用>

onRun 和 onBeforeAction 钩子现在需要你调用 this.next()，并且不再需要 pause() 参数.所以默认行为是相反的.例如，如果您有:

Router.onBeforeAction(function(pause) {如果 (!Meteor.userId()) {this.render('登录');暂停();}});

<块引用>

您需要将其更新为

Router.onBeforeAction(function() {如果 (!Meteor.userId()) {this.render('登录');} 别的 {this.next();}});

<小时>

更多信息

在您的情况下，书本上的修复方法是在 onBeforeAction 的末尾添加 this.next().但是，您应该使用 waitOn:

waitOn:函数(){return Meteor.subscribe("userData");}

这样，您可以设置一个 loadingTemplate，它会在 userData 订阅加载时出现.

Is anyone else getting the following error from Iron-Router since upgrading Meteor to version 1.0?

Please post here if you know how to resolve this issue.

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

Router.map(function () {
    Router.route('profileShow', {

        waitOn: function () {
            if (Meteor.user()) {
                Meteor.subscribe('userData');
            } else {
                this.next();
            }
        },

        data: function () {
            if (Meteor.user()) {
                return {profile: Meteor.user().profile};
            }
        }
    });
});

解决方案

There was a non backwards-compatible change in the newest version of Iron Router. The migration guide says:

onRun and onBeforeAction hooks now require you to call this.next(), and no longer take a pause() argument. So the default behaviour is reversed. For example, if you had:

Router.onBeforeAction(function(pause) {
  if (! Meteor.userId()) {
    this.render('login');
    pause();
  }
});

You'll need to update it to

Router.onBeforeAction(function() {
  if (! Meteor.userId()) {
    this.render('login');
  } else {
    this.next();
  }
});

More information

In your case, the by-the-book fix would be to add this.next() at the end of onBeforeAction. However, you should rather use waitOn:

waitOn: function () {
  return Meteor.subscribe("userData");
}

That way, you can set a loadingTemplate which will appear while the userData subscription is loading.
