MongoDB schema validation - sub schemas with oneOf or $or - mongodb

Question

I have the next validation schema
use("bio_db_schema")
For Biology
const biologyChapterSchema = {
bsonType: "object",
additionalProperties: false,
properties: {
"chapter_name": {enum: ["Biologia"]},
"taxonomias": {
bsonType: ["array"],
items: {
bsonType: "object",
// required: ["taxonomia_name"],
additionalProperties: false,
properties: {
"valor": {bsonType: "string"},
"taxonomia_name": {bsonType: "string"},
"taxonomia_id": {bsonType: "objectId"},
"associates": {
bsonType: ["array"],
items: {
bsonType: "object",
additionalProperties: false,
properties: {
"associate_name": {bsonType: "string"},
"associate_role": {bsonType: "string"},
"associate_id": {bsonType: "objectId"},
},
},
},
},
},
},
}
};
For Physics (just for test, i change the "valor" from "string" to "double")
const physicsChapterValidation = {
bsonType: "object",
properties: {
"chapter_name": {enum: ["Fisica"]},
"estaciones": {
bsonType: ["array"],
items: {
bsonType: "object",
// required: ["taxonomia_name"],
additionalProperties: false,
properties: {
"valor": {bsonType: "double"},
"estacion_name": {bsonType: "string"},
"estacion_id": {bsonType: "objectId"},
"associates": {
bsonType: ["array"],
items: {
bsonType: "object",
additionalProperties: false,
properties: {
"associate_name": {bsonType: "string"},
"associate_role": {bsonType: "string"},
"associate_id": {bsonType: "objectId"},
},
},
},
},
},
},
}
};
Schema
db.createCollection("projects", {
validator: {
$jsonSchema:{
bsonType: "object",
// title: "",
// required: ["chapter_name"],
additionalProperties: false,
properties: {
"_id": {bsonType: "objectId"},
"project_name": {bsonType: "string"},
"sub_projects": {
bsonType: ["array"],
items: {
bsonType: "object",
additionalProperties: false,
properties: {
"sub_project_name": {bsonType: "string"},
"IGA": {bsonType: "string"},
"sub_project_stage": {
bsonType: ["array"],
items: {
bsonType: "object",
additionalProperties: false,
properties:{
"sub_project_stage_name": {bsonType: "string"},
"chapters": {
bsonType: ["array"],
items: {
oneOf: [
biologyChapterSchema,
physicsChapterValidation
]
}
}
},
},
},
},
},
},
},
},
},
});
What i expect:
When i insert a document with:
"chapter_name" = "Biologia", it must use the Schema "biologyChapterSchema" (where "valor" is a "string")
"chapter_name" = "Fisica", it must use the Schema "physicsChapterValidation" (where "valor" is a "double")
i use "oneOf" for it,
works for "Biologia", only accept a string, but when i change to "Fisica" it allows "strins", "integers" and allow another properties like "valor2".
I use VSCode extensión and said $or operator doesnt work for $jsonSchema
Those are just a test for my app, I need that they are in variables to make it readable and to be able to keep it over time and add more sub schemas.
Any tips?
For test:
db.projects.insertOne({
"project_name": "Proyecto Fisica",
"sub_projects": [
{
"sub_project_name": "Subproyecto Fisica",
"IGA": "IGA Fisica",
"sub_project_stage": [
{
"sub_project_stage_name": "Etapa Fisica",
"chapters": [
{
"chapter_name": "Fisica",
"taxonomias": [
{
"taxonomia_name": "Taxonomía Fisica",
"taxonomia_id": ObjectId("123456789235"),
"associates": [
{
"associate_name": "Asociado Fisica",
"associate_role": "Rol Biología",
"associate_id": ObjectId("123456789232")
}
],
"valor": "asdasd"
}
]
}
]
}
]
}
]
})

You are missing additionalProperties in physicsChapterValidation.
const physicsChapterValidation = {
bsonType: "object",
additionalProperties: false,
properties: {
"chapter_name": {enum: ["Fisica"]},
