meteor dynamic meta tags - dynamic

Question

Well, i need some way to have a dynamic meta tags for my app, im creating a cms-blog so ill need to change the meta desc/keywords/title etc at every post,im using iron-router.
i have an idea how to do so using not completely sure:
<template name="post">
{{metaTitle}}
</template>
Template.post.metaTitle = function (this) {
document.title = this;
}
(iron-router version)
this.route('post', {
path: '/',
....
data: function () {
return Posts.findOne({_id: this.params._id});
}
//Posts holds post documents with a fields like: "metaTitle" "metaKeywords" etc
});
so if a client routes to "/" and the Posts collection holds a post with id of "/"
and the document holds metaTitle:"Post 1"
will this proceed to the template.post.metaTitle helper
and the title will be "Post 1"?
is there a better way?
and doing similar stuff to the keywords etc.

Answer 1

ok , i have manged to do this, here is what i'v done:
html:
<template name="posts">
{{metaTitle}}
{{metaDesc}}
{{metaKeywords}}
{{>home}}
{{#each posts}}
</div>
<a href="{{pathFor 'post'}}">
<div class="small-12 medium-12 large-12 columns">
<div class="post">
<div class="small-12 medium-12 large-12 columns">
<h4 class="left">{{author}}</h4>
<h4 class="right">{{date}}</h4>
</div>
<h2>{{title}}</h2>
<p>{{desc}}</p>
</div>
</div>
</a>
<hr/>
{{/each}}
</template>
router (iron-router):
this.route('posts', {
path: '/',
waitOn:function(){
NProgress.start();
Meteor.subscribe("Teams");
},
before: function () {
Session.set("adding_group", false);
NProgress.done();
/*
causes problems when phonegap mode
*/
},
fastRender:true,
unload: function () {
Session.set("adding_group", true);
Session.set("group_name", false);
Session.set("group_date", false);
Session.set("group_friends", false);
Session.set("group_location", false);
Session.set("group_rules", false);
Session.set("group_desc", false);
Session.set("group_save", false);
},
yieldTemplates: {
'nav': {to: 'header'}
},
data:{
posts:Posts.find({}),
metaTitle:function(){
var one = Posts.findOne({}); //just for the example
return document.title = one.title; //just for the example
}
}
});
this will insert a document.title of the posts if ill do this dynamic path segments
( findOne by ID ) it will return the current post title,
i think ill make this simple thing a package, i haven't seen similar package at atmosphere.
hope it helps you guys.
