Improve val() func inside upsert (JSON and Facets) #3940
Description
JSON mutation support seems to be missing:
{
"query": "{ u as var(func: has(amount)) { amt as amount} me () { updated_amt as math(amt+1)}}",
"set": [
{
"uid": "uid(u)",
"amount": {
"uid": "val(updated_amt)"
}
}
]
}
{
"errors": [
{
"message": "strconv.ParseUint: parsing \"val(updated_amt)\": invalid syntax",
"extensions": {
"code": "ErrorInvalidRequest"
}
}
],
"data": null
}
Add val for facets in mutation.
ref: #1996
upsert {
query {
me(func: eq(email, "aman@dgraph.io")) {
v as uid
edge as someEdge @facets(r as rating, t as something, e as somethingElse)
}
}
mutation {
set {
uid(v) <someEdge> uid(edge) (weight=0.1, updated_at=2019-06-02T13:01:09, val(r), val(t), val(e)) .
}
}
}
As JSON
{
"query": "{ u as var(func: eq(email, \"aman@dgraph.io\")) { edge as someEdge @facets(r as rating, t as something, e as somethingElse)}}",
"set": [
{
"uid": "uid(u)",
"someEdge|weight": "0.1",
"someEdge|updated_at": "2019-06-02T13:01:09",
"someEdge|rating": "val(r)",
"someEdge|something": "val(t)",
"someEdge|somethingElse": "val(e)"
}
]
}
