How to put a file of some contentType into the pageBundle of another contentType on creation?

[pauko]

Hello community!

In my metamodel of records I have the entities Solution, Problem, Opportunity, Goal, whereas Solution is some kind of container, which "aggregates" all other entities. Let's visualize this for better understanding with a class diagram:

classDiagram
  class Solution
  class Problem
  class Opportunity
  class Goal

  Solution --o Problem
  Solution --o Opportunity
  Solution --o Goal

In fact, in the .md files I have a contentRelationship from the other entities towards Solution by slugs - so the reference goes from child to parent!

I want to establish a structure in my content folder, so that each Solution gets its own subdirectory in some contents directory, and all Problems, Opportunities, and Goals that are associated with some Solution are placed in that corresponding subdirectory - ideally on creation of the .md file when setting the reference to the Solution.

contents/
├─ Solution A/
│ ├── index.md
│ ├── problem-1-of-A.md
│ ├── problem-2-of-A.md
│ ├── goal-1-of-A.md
├─ Solution B/
│ ├── index.md
│ ├── problem-1-of-B.md
...

My first idea is to use pageBundle: true for the Solution content type, which would give me the subdirectories (and an index.md).

However, how can I configure the other entities, so that when I set the contentRelationship to the Solution in the frontmatter of some .md, this .md file is placed into the subdirectory of that Solution?

I read the Placeholders section of the documentation, but I don't find a good fit - and I'm a little bit hesitating to go for the custom placeholders with their scripting abilities.

Is there something less sophisticated for my use case?

Hi @pauko, that is an exciting structure you have there, and if I had the same use case, I would approach it the same way.

The solution is the easiest: creating a new page as a page bundle. The other types are a bit trickier, as they need to know the parent folder they need to make. There is nothing yet in Front Matter CMS that allows you to accomplish this with the default features.

What could work is the postScript functionality on the content type, which allows you to run a script after the content is created. So you can move it to the correct folder. - https://frontmatter.codes/docs/content-creation/content-types#run-a-script-after-your-content-is-created

Feel free to give suggestions on what would help you to get your content created.

What I could think of is that we can introduce a subContent property on the content type where you can specify the content to look for and propose that during the content creation.

Example:

When you want to create a problem, FM proposes to you: Under which <content type> would you like to create the content: ...

And, of course, it would be nice if this semantics of subContent worked recursively, thus building a hierarchy of subdirectories on the filesystem.

During the content creation, we are not yet checking the fields. There is only validation on the content-type and its properties.

What you are proposing is to add some more logic to the contentRelationship field, which I get, but can also be tricky when configuring multiple fields. Another issue I could see is when adding it to the field, would it mean we have to move the file each time the option is changed?

When we would add it to the root of the content-type, it would only be used once for placing the file in the correct location.

I've done the first steps to allow you to select the folder where the sub-content must be created. Check issue #722 to see how you can configure it. You can give it a try in the latest beta version.
