I have a Course content type which has several "modules." (A module is just a name.) There are also several "units," which may or not belong to a module. A unit has several fields, for example Location, Description.

I have created a Course unit paragraph type, and a Units field in the "course" content type, which references this paragraph type. That way I can create units that belong to the course.

However, I'm not sure how to deal with modules. I could create a Course module paragraph type, but I don't think it would enable me to attach a unit to a module, since there's no way to select an existing paragraph.

Basically I need to create several modules inside a node, then several units, and optionally attach these units to one of the modules I've created.

  • Are modules unique to a course? Can units belong to multiple modules? Can multiple units belong to the same module? What's different about a unit if it's attached to a module vs not?

  • Yes, modules are unique to a course. Units cannot belong to multiple modules, but multiple units can belong to the same module. There is no difference between a unit that belong to a module vs not. In a way units are tagged with a module, so I've ended up setting up modules as a taxonomy vocabulary (with a content reference field that point to a course)

Given what you have done so far I would recommend:

  • Create a "Modules" taxonomy.
  • Make this a hierarchical taxonomy that includes course names (as if courses were top level modules) and then add the modules under those.
  • Add a taxonomy reference field to your Unit paragraph
  • This will be flexible in a couple of ways:
    • It will let modules receive descriptive fields as needed later.
    • It will allow site search and filter by module in a hierarchy that includes courses.
    • It will allow for modules within modules if that becomes a later requirement.

Optional improvements

  • Make the module selector field on the Unit paragraph form use a view that filters by the current course name as parent (with depth)

  • Thank you, that's a great idea! I've ended up setting up a "course module" taxonomy (although I kept it simple, with just a name and course reference), and tagged each course unit with a term.
