Dynamic pages with nested json data files?

Hey fellow coders,

I try to achieve the following with middleman (after I was unhappy with Jekyll Collections ;-)):

Collect video data in a file per video publisher (e.g. a channel provider).
So there is a) general publisher information and b) a list of items (videos)

The goal in a template would be:

  • display general publisher information (all the same for the videos)
  • display specific video information

Each video should have it’s own .html file/URL afterwards.

My approach:

    "name": "Civil Engineering RWTH Aachen University",
    "description":"Open Educational Resources Initiative by the Faculty of Civil Engineering of the RWTH Aachen University.",
    "@context": "https://schema.org",
    "@type": "VideoObject",
    "name": "ELVA - The Railway Signalling Lab",

    "description": "Railway safety and operation are two very complex topics.

Breach formation processes and its influencing factors are still subject to a number of uncertainties. In that context, physical model tests of dike breaches were performed in the hydraulic laboratory in Aachen to quantify the targeted filling of flood polders.",

    "learningResourceType": "video",

Now i want to create subpages and also create a slug with .paramaterize (found via https://cobwwweb.com/dynamic-routing-in-middleman):


data.publisher1.items.each do |item|
  proxy "/videos/{item.name.parameterize}.html", "/templates/video-detail-page.html",
  #vars only for templates?
  locals: { current_video: item, publisher:data.publisher1.publisher},
  ignore: true

Unfortunately this is not working right now, output is:

create  public/videos/{item.name.parameterize}.html
 identical  public/videos/{item.name.parameterize}.html

Is this use-case even supported by data files?

Thanks in advance! Cheers!

Use "#{}" for snippet injections (you don’t have the hashtag in your code example)

Thanks very much!
