I was trying to use @SoftDelete feature on a timestamp column (more precisely timestamp without time zone in PostgreSQL) such that null means it is active and having (timestamp) value means it is soft-deleted.
Here is a converter:
class DeletedAtConverter : AttributeConverter<Boolean, LocalDateTime> {
override fun convertToDatabaseColumn(attribute: Boolean): LocalDateTime? {
return if (attribute) {
LocalDateTime.now()
} else {
null
}
}
override fun convertToEntityAttribute(dbValue: LocalDateTime?): Boolean {
return dbValue == null
}
}
and Entity definition:
@Entity
@SoftDelete(columnName = "deleted_at", converter = DeletedAtConverter::class)
class MyEntity(
// other properties are omitted
@Column(name = "deleted_at", insertable = false, updatable = false)
var deletedAt: LocalDateTime? = null,
)
Note that convertToDatabaseColumn returns null if attribute is false, and due to this Spring could not be loaded with error log I put at the bottom of this post (null assertion failed error).
I had tested a bit and found that returning null in convertToDatabaseColumn cause the problem, and I wonder if this is an expected behavior (i.e. Should I not use @SoftDelete for timestamp based soft-delete?). Note that the application run without an issue if I return any LocalDateTime other than null.
