Deserialize not-constructor params (native)

[qcho]

Hi.

I'm using the native driver. It seems the deserialization is not working for "not constructor" fields.

When i check the database. The data is saved properly!

> db.document2.find()
{ "_id" : 10, "field1" : "Hola", "field2" : "Mundo" }

    data class Document2(@BsonId val id: Int) {
        var field1: String? = null
        var field2: String? = null
    }

    @Test fun testMongoRecord() {
        val client = KMongo.createClient()
        val database = client.getDatabase("test")

        run {
            val record = Document2(10)
            record.field1 = "Hola"
            record.field2 = "Mundo"

            val col = database.getCollection<Document2>()
            col.drop()
            col.insertOne(record)

            val fromDb = col.find().first()!!
            assertEquals(10, fromDb.id)
            assertEquals("Hola", fromDb.field1) <-- FAILS field1 is null
            assertEquals("Mundo", fromDb.field2) <-- FAILS field2 is null
        }
[...]

I hoped it would use the public setters

Also, I found this workaround. But I'm working with 30+ fields, creating this placeholder properties is error-prone.

    class Document2(
            @BsonId val id: Int,
            _field1: String? = null,
            _field2: String? = null
    ) {
        var field1: String? = _field1
        var field2: String? = _field2
    }

@qcho I think you forgot to use the .coroutine extension applied (your choice) to the client, database or collection. Look at these tests: https://github.com/Litote/kmongo/blob/master/kmongo-coroutine-core-tests/src/main/kotlin/org/litote/kmongo/coroutine/ReactiveStreamsFindOneTest.kt where

val col by lazy { rule.col.coroutine }

Ok. I have not seen that the properties are not in the constructor. I'm going to check that.

Thanks for reporting, the fix is in the snapshot
