I'm trying to add a unique composite key in my document as follows:
@Document
@CompoundIndexes({
CompoundIndex(def = "{'firstName':1, 'lastName':1}", name = "compound_index_1", unique = true)
})
But I'm getting the error:
An annotation argument must be a compile-time constant.
can anybody help me?
Arrays are passed to annotations differently in Kotlin. Check out the docs on kotlinlang and you'll see this snippet down near the bottom:
// Kotlin 1.2+:
@AnnWithArrayMethod(names = ["abc", "foo", "bar"])
class C
// Older Kotlin versions:
@AnnWithArrayMethod(names = arrayOf("abc", "foo", "bar"))
class D
So your curly braces aren't going to work here, you'll need square brackets.
@Document
@CompoundIndexes(value = [
CompoundIndex(def = "{'firstName':1, 'lastName':1}",
name = "compound_index_1", unique = true)
])
