meteorjs iron-router waitOn并用作渲染的数据

问题描述：

我尝试在Template.rendered函数中获取返回的数据.

I try to get the returned data in my Template.rendered function.

当前代码为:

this.route('editCat', {
    layoutTemplate : 'layoutCol2Left',
    template : 'modCategoriesEdit',
    path : '/mod/categories/edit/:_id',
    yieldTemplates : _.extend(defaultYieldTemplates, {
    'navigationBackend' : {to : 'contentLeft'} 
    }),
    waitOn : function () {
         return Meteor.subscribe('oneCat', this.params._id);
    },
    data : function () {
         return Categories.findOne({_id : this.params._id});
    }
 });

在此块中，我等待对Collection Document的订阅，然后将文档作为数据返回.

In this block i wait on the subscribtion of the Collection Document and return the Document as data.

现在我可以像这样在我的模板中使用返回的文档了:

Now i can use the returned Document in my Template like this:

<template name="modCategoriesEdit"> 
    <h1>Edit {{name}}</h1>
</template>

我的问题是我必须在渲染函数中使用返回的数据，如下所示:

My problem is that i have to use the returned data in my rendered function like this:

Template.modCategoriesEdit.rendered = function () {
    console.log(this.data);
}

但这将返回"null".

But this returns "null".

所以我的问题是: 如何在渲染函数中访问返回的数据?

So my question is: How is it possible to get access to the returned data in the rendered function ?

答

解决方案:

只需将以下内容添加到您的铁路由器route()方法中即可.

Just add the following to your iron-router route() method.

action : function () {
    if (this.ready()) {
        this.render();
    }
}

比正确加载所有模板后，模板将呈现.

Than the Template will rendered after all is loaded correctly.
