What is the best approach to update sub document in couchbase ? I am taking about nested json documents . Simple fields are easily updatable using syntax like set name = 'Jon Doe'
but what about nested json document . I have read all the pages in the official document but all the pages used a phase called keys
or path
which is a json path.
So for a complex nested json like org.adddress.city.name how to find the path dynamically or programmatically from json . Think a nested json with 6-7 level deep . Its hardly be seen but what about it .
Sub document updating in couchbase means updating a portion or part of the entire document or updating a simple field that could be nested .
My way is to find a Merge Json Patch that will give me which json field is updated and then if that patch contains nested fields like
"address": {
"city": {
"id": "25",
"name": "Atlanta"
}
}
then to update this in Couchbase using mutate_in function I need those path which is address.city.id
and address.city.name
. Even if in N1QL query to update the doc I need to generate those path I believe .
I have been trying to generate those path from json using recursion function because you don’t know how far the next will be . Here is the gist .
I would like to know If there are any other way without generating the path to update complex sub documents.
