What I want to do
Get a total count of groups. Using groupby to group by a predicate value, want to know how many groups there are for pagination.
What I did
This is the query I’m using:
query q($lexicon: string, $first: int) {
var(func: type(Lexicon)) @filter(eq(Lexicon.language, "EN")) {
Lexicon.lexicalEntries {
LE as uid
}
}
var(func: uid(LE)) @groupby(headword: LexicalEntry.headword, count) {
H as count(uid)
}
q(func: uid(H)) {
total: val(H)
}
}
I get the following error: "Vars can be assigned only when grouped by UID attribute".
I think this might be the fix? but looks like it hasn’t been merged into any release yet? feat(DQL): @groupby on scalar fields and count duplicate by minhaj-shakeel · Pull Request #7746 · dgraph-io/dgraph · GitHub
