How to set a field on relationTo media with name of parent collection.

[ionic tusk]

I have a collection with a media field

// media collection
{
  slug: "media",
  fields: [
    { name: "parentCollection", type: "text" }
  ]
}
// User collection
{
  slug: "users",
  fields: [
    { name: "photo", relationTo: "media" }
  ]

on the admin screen when i create a new user i want to upload a photo, and when i upload a photo i know it goes into the media collection, but how would I populate the parentCollection field automatically so it references "users"?

Did you ever find a solution to this? Would be nice to set values from the parent

no 😦

did you try using one of the hooks? nit

I feel like we shouldn't need to use a hook to do something like this, I know you could grab the id from the url but I am running into the same issue. If I am on an admin screen, and I want to add a related piece of content, why wouldn't it autopopulate this for me? It seems counter intuitive.

You do this with an afterChange collection hook (in the user collection) that will update the related media doc.

If you want normalized data, you should use a join table.
