Dynamic layout of locations and categories

[xingyzt]

In the ahs-app database, the layout is isolated from the articles themselves. The layout is an ordered list of location objects. Each location object has an ordered list of category objects, which in turn hold article IDs. In addition, location and category objects have the properties "title" and "id": The titles are for display (e.g. "General Information") and ids for semi-permanent references (e.g. "General_Info").

Implementing the layout list will allow content editors to add, modify, and delete categories in real time.

Below is a pseudocode for generating the layout from the database.

database := app.database("ahs-app")
locations := database("layout")
snippets := database("snippets")

for each location in locations:
  insert_in_app(location.title,location.id)
  for each category in location.categories:
    insert_in_location(location.id,category.title,category.id)
    for each id in category.articleIDs:
      snippet := snippets[id]
      insert_in_category(category.id,snippet)
      snippet.onclick:
        article := database("articles/"+id)
        show_article(article)
