So I noticed here that you can use the doc
field in the update API to update single fields. However, I can't seem to get this working when the field is not at the root of the document, without erasing the other fields in the subobject. For example, if I have a document with this structure:
{
"parent": {
"child1":1,
"child2":2,
"child3":3,
"child4":4
}
}
How can I update ONLY child2
? If I send {"parent":{"child2":5}}
, that will replace the whole parent
object. I had thought that maybe I could do {"parent.child2":5}
, but that appears to create a new field with the literal name parent.child2
. Is what I'm trying to do possible? I know I can retrieve the current value of parent
, modify it client-side and resend, but wouldn't there be potential race conditions from that? Thanks.
