Prisma

I don't get it. How can I specify nullable array?

But it says Possible Formats: `File`, `File!`, `[File!]!`

<https://www.prisma.io/forum/t/is-it-possible-to-create-a-to-many-relation/3874/4?u=nilan>

"The relation field `documents` has the wrong format: `[File!]` Possible Formats: `File`, `File!`, `[File!]!`"

documents: [File!] @relation(name: "ProjectDocuments")

You cannot specify a nullable `to-many` relation.

Did you read my elaborate post in the Forum on this?

to have one model have optionaly related many other models

a `Document` can have many `File`. Or not to have

`[Model!]!` works for this. As I've written in the Forum, the default value is `[]`.
