Hi team,
Am working on an app which aims to updated external database(Mongo DB) and for this we are using Mongo DB connected system.
Now we have a use case where we must update an existing collection entry with new details, and we are facing problem to update it correctly.
Below is my collection structure.
Col A
Col B
Col C [
{NestColC1A, NestCol C1B, NestColC1C},
{NestColC2A, NestCol C2B, NestColC2C},
]
Col D
[
{NestColD1A, NestCol D1B, NestColD1C1[
{NestNestColD1C1A1, NestNestColD1C1B1, NestNestColD1C1C1},
{NestNestColD1C1A2, NestNestColD1C1B2 NestNestColD1C1C2},
{NestNestColD1C1A3, NestNestColD1C1B3, NestNestColD1C1,C3},
},
{NestColD2A, NestCol D2B, NestColD2C1[
{NestColD2C2A1, NestColD2C2B1, NestColD2C2C1},
{NestColD2C2A2, NestColD2C2B2 NestColD2C2C2},go on
}
Basically, Col D has vector value in one of its vector element(NestColD2C*)
And now the requirement is that we want to update the existing record(or existing Document in MongoDB’s context) with a new entry for col D’s vector element i.e
We are trying to insert below entry to existing record: NestColD1C1: [
{NestNestColD1C1A4, NestNestColD1C1B4, NestNestColD1C1,C4},
So post update my structure should look like:
{NestNestColD1C1A4, NestNestColD1C1B4, NestNestColD1C1,C4}
We have tried $addToSet function but the output we got was like this:
NestColD1C1[
Which is incorrect structure.
The query to wrote in our update section was below:
$addToSet:{
NestColD1C1{
NestNestColD1C1A4: ri!value,
NestNestColD1C1B4: ri!value2…….
We also tried using dot notation like below but no luck $addToSet:{
NestColD1C1.NestNestColD1C1A4: ri!value,
NestColD1C1NestNestColD1C1B4: ri!value2…….
Any help on this matter would be great and much appreciated.
Thanks
