[SOLVED] How to find all the posts with a specific tag in Ghost and iterate over them?

How to find all the posts with a specific tag in Ghost and iterate over them?

I'm currently working on a Ghost blog (Ghost is a Wordpress "successor" that is based on Node.js and other various packages/libraries on that platform), but I'm wondering how I might be able to grab all the posts that have a certain tag in Ghost/Handlebars.js.

The problem is that Ghost's contexts are usually encapsulated to the point that I can't extract a list of all the posts bearing a certain tag out of the API; it's apparently only possible to iterate through the posts from index.hbs, and other solutions are a bit hacker-y or involve more use of jQuery.

How might I be able to get a list or array of all the posts in Ghost so that I can filter them by tag and then iterate over them? I've even tried a {{#foreach posts}} and {{#has tag='WHATEVER'}} but this method doesn't seem to work out of the box. As a newbie to Ghost and Handlebars, I'm unsure of what to do.

Solution

In case anyone comes across this still, this is now possible. Here is how you can do it via the get helper:

{{#get "posts" filter="tags:tagname"}}
    {{#foreach posts}}
         <p>{{title}}</p>
    {{/foreach}}
{{/get}}

{{#get "posts" filter="tags:[tag1, tag2]"}}
    {{#foreach posts}}
         <p>{{title}}</p>
    {{/foreach}}
{{/get}}
