Iron Router onBeforeAction没有被调用 [英] Iron Router onBeforeAction isn't being called

问题描述

我设置了/user路由，如果当前用户未登录，该路由应该呈现login模板.整个路由器都有一个waitOn等待currentUser订阅结束.问题是当我转到/user时，它只是呈现了dataNotFound模板.

I have a /user route set up, which is supposed to render the login template if the current user isn't logged in. The entire router has a waitOn that waits for the currentUser subscription to finish. The problem is that when I go to /user it simply renders the dataNotFound template instead.

以下是与这种情况相关的代码段.我一直很小心地按照它们在我的lib/router.js文件中定义的顺序向您显示.

Here's the snippets of code that are relevant to this situation. I've been careful to show you them in the order they're defined in my lib/router.js file.

Router.plugin('dataNotFound', {notFoundTemplate: 'notFound'});

Router.onBeforeAction(function () {
    console.log(Meteor.userId())
    if (!Meteor.userId()) this.render('login');
    else this.next();
}, { only: ['user'] });

Router.configure({
    waitOn: function () { return Meteor.subscribe('currentUser'); }
});

Router.route('/user', {
    name: 'user',
    template: 'userView',
    data: function () { return Meteor.user(); }
});

上面的console.log甚至不会触发.在我看来，由于即使应该最初呈现dataNotFound也是应该是一个反应函数，所以之后不久应该触发onBeforeAction并呈现login模板，对吧?

That console.log above doesn't even ever fire. It seems to me that since it should be a reactive function that even if initially the dataNotFound is rendered, then soon after that the onBeforeAction should be fired and render the login template, right?

推荐答案

从流星0.9.1升级到1后，onBeforeAction挂钩出现问题. 它没有在应有的时候被解雇.就像注销后一样，我手动输入地址，而不是登录页面，我看到的是实际站点在等待从未出现的数据. onRun挂钩解决了它，但正如文档所说，它只被触发了一次.

I had a problem with onBeforeAction hook after upgrading from meteor 0.9.1 to 1. It didnt get fired when it should. Like after I log out, I enter address manually and instead of login page I can see the actual site waiting for data that never comes. onRun hook solved it, but as docs says it gets fired only once.

Router.onRun(function () {

    if (!Meteor.userId()) {
       this.render('login'); 
    } else { 
       this.next();
    }
}, { only: ['user'] });
