Update array object mongoDB

[nextNluwi]

Hello everyone,

I have an array of objects and would like to update the count of the object where categoryId = “menu2” and subCategoryId = “1”.

in my mongodb i currently have two records in the array:

{
    "_id": "xyz",
    "badges": [{
        "count": 2,
        "categorieId": "menu1",
        "subCategorieId": "1"
    }, {
        "count": 1,
        "categorieId": "menu2",
        "subCategorieId": "1"
    }]
}

if i now execute the following method the object with categorieId “menu1” will be updated and not my menu2…

return getCollection()
      .updateOne(
        and(
          eq("badges.categorieId", "menu2"),
          eq("badges.subCategorieId", "1")
        ),
        Updates.inc("badges.$.count", 1)
      );

I am using the io.quarkus.mongodb.reactive.ReactiveMongoCollection.

Thanks in advance!

The filtered positional operator $[identifier] is working:

return getCollection().updateOne(
      eq("_id", "xyz"),
      Updates.combine(
        Updates.inc("badges.$[badges].count", 1)
      ),
      new UpdateOptions()
        .arrayFilters(Arrays.asList(
          and(
            eq("badges.categorieId", "menu2"),
            eq("badges.subCategorieId", "1")
          ))));

But shouldn't the other method also work?
