I want to use the Atlas device sync feature of Mongo DB in my Application. I have modeled a BankAccount class in my Kotlin code like this.
open class BankAccount: RealmObject, Searchable { @PrimaryKey var _id: ObjectId = ObjectId() var accountHolderName: String = "" var accountNumber: String = "" var accountType: String = "" var bankName: String = "" var cardCvv: String = "" var cardNo: String = "" var cardPin: String = "" var expiryDate: String = "" var haveBankingApp: Boolean = false var haveCard: Boolean = false var haveUpi: Boolean = false var ifscCode: String = "" var isArchived: Int = 0 var loginPin: String = "" var nameOnCard: String = "" var ownerId: String = "" var regEmail: String = "" var regMobNo: String = "" var remarks: String = "" var transactionPin: String = "" var upiPin: String = "" override fun doesMatchSearchQuery(query: String): Boolean { return bankName.contains(query.trim(), ignoreCase = true) || accountHolderName.contains(query.trim(), ignoreCase = true) }}My JSON Schema looks like this:
{"title": "BankAccount","properties": {"_id": {"bsonType": "objectId" },"ownerId": {"bsonType": "string" },"bankName": {"bsonType": "string" },"accountHolderName": {"bsonType": "string" },"accountType": {"bsonType": "string" },"accountNumber": {"bsonType": "string" },"ifscCode": {"bsonType": "string" },"regMobNo": {"bsonType": "string" },"regEmail": {"bsonType": "string" },"remarks": {"bsonType": "string" },"haveCard": {"bsonType": "bool" },"nameOnCard": {"bsonType": "string" },"cardNo": {"bsonType": "string" },"expiryDate": {"bsonType": "string" },"cardCvv": {"bsonType": "string" },"cardPin": {"bsonType": "string" },"haveUpi": {"bsonType": "bool" },"upiPin": {"bsonType": "string" },"haveBankingApp": {"bsonType": "bool" },"loginPin": {"bsonType": "string" },"transactionPin": {"bsonType": "string" },"isArchived": {"bsonType": "int" } },"required": ["_id","ownerId","bankName","accountHolderName","accountType","accountNumber","ifscCode","regMobNo","regEmail","remarks","haveCard","nameOnCard","cardNo","expiryDate","cardCvv","cardPin","haveUpi","upiPin","haveBankingApp","loginPin","transactionPin","isArchived" ]}Everything is perfect. I have enabled device sync correctly set the permissions in the right way and also configured the Mongo DB realm perfectly, but I am still constantly getting this error of the primary key :(
