Description
In my database when i have Int variable in my RealmObject, when i migrate I want to parse different value if some value is already given in old database version.
When i try to access the value or to set the value as Int i get error:
java.lang.IllegalArgumentException: Trying to access property 'Dog.legs' as type: 'class kotlin.Int' but actual schema type is 'class kotlin.Long'
If i redeclare it as a Long, everything works good, but why should i declare it as Long since in my database i declare it as Int, here small snippet, will also attach Demo and Log output:
My object:
open class Dog() : RealmObject {
@PrimaryKey
var type: String = "TEST DOG"
var legs: Int = 0
}
When i try doing something like this, access variables as Int:
migrationContext.enumerate("Dog")
{ oldObject, newObject -> newObject?.set("legs", oldObject.getValue("legs", Int::class)) }I get error that i declared above, here is stackTrace
