Is there way out to update UUID value to null or blank in cassandra using mapper. As in string we can do it by using ' ' .How to do it in case Of UUID

valchkou commented 9 years ago

you can do this if your UUID field is not a part of primary key You may set null to object value and save or call deleteValue(fieldName)

Thanks Eugene , but by deleting the field will i be able to update that value again, or the coloumn will be deleted permanentaly. And if updatevalues function the last argument is object

valchkou commented 9 years ago

delete operation just deletes value, not a column and you can re-assign value again. anyway I am working on fix for update.
