I am trying to delete the address result from here. I can add new address by doing this but I can't delete it
$User.find_by_id(19).update(address: "canada")
I tried this but it is not working
$User.find_by_id(19).destroy(address: "canada")
The output of
$User.find_by_id(19).destroy(address: "canada")
User Load (1.3ms) SELECT "users".* FROM "users" WHERE "users"."id" = $1 LIMIT 1 [["id", 19]]

I think you are trying to update the address
field value from Canada
to nil
. If that's the case, what you are looking for is update, not destroy:
User.find(19).update(address: nil)
