QUESTION
I'm trying to update many objects within a nested array when their IDs exist in a list.
The document structure is like so:
...ANSWER
Answered 2021-Sep-08 at 03:06You can do it with pipeline update.
Pipeline updates allows us to use all aggregate operators, so we can do complicated updates (in your case maybe its possible with update operators also, but with pipeline its easy)
Pipelines updates require >= MongoDB 4.2.
Query
- match on
id=p00
- map each member(
$$c
variable) of the children array
if$$c.id
in the list["c00","c01"]
then member merge$$c
with{"value" : false}
(its like add key value pair)
else dont change$$c
