Iterate through MongoDB collection with Meteor.js

I m learning Meteor and I m building a very basic app for practice purposes. I just installed Collection FS and I m uploading files using the cfs:filesystem. I have a collection named todos witch has the following fields among others :

"files" : [ "/cfs/files/files/HPxaJrEbvNjcnmA6m/files?store=files", "/cfs/files/files/jfKua2BszyfqiKYYu/files?store=files" ]

The insert is done via method on Server side:

'addFiles':function(id,url){
  todos.update(id, {
    $push: {files:url}
  });

How can I iterate through these to put them in urls in my template?

What I tried in my template is :

{{#each todos}}
{{#each files}}<a href="{{files}}" target="_blank"> file</a>{{/each}}
{{/each}}

Buts this renders just <a target="_blank"> file</a> In case the files object hasn't got any values I dont want to show any url. How can I do this?

I assume that you are properly subscribing to todos collection and have helper:

Template.NAME.helpers({
    todos : function(){
       return todos.find();
    }
})

In template NAME try this:

{{#each todos}}
   {{#each this.files}}
     <a href="{{this}}" target="_blank"> file</a>
   {{/each}}
{{/each}}

If files is empty, then nothing will be shown.
