Unable to alter schema

What I want to do

I’m trying to add two new types to the DQL Schema.

What I did

In Ratel, I clicked on “Schema >> Bulk Edit”, then pasted this Schema text:

mixed_med_name: string .

type MixedMed {
  mixed_med_name
}

mixed_med: [MixedMed] .

type MedicationOrder {
  mixed_med
}

But when I click on “Apply Schema”, I get the error message:
Could not alter schema: line 7 column 12: Undefined Type.

Any ideas how to fix this?

In the DQL schema, instead of mixed_med: [MixedMed] ., you’ll do:

mixed_med: [uid] .

It is up to your code to make sure the uid you connect with is of type MixedMed. At the DQL level, Dgraph doesn’t type check the uid for you.

Ah! Thank you so much, @RickSalmon , for the fast reply!
I apologize for the rookie mistake. I frequently confuse myself with the GraphQL syntax vs DQL.
