Try:
scope :in_account, lambda { |account_id|
where(account_id: account_id) if account_id != "*"
}
If the conditional fails, this will just not interfere with the query.
If it's possible that account_id will be nil or blank (as on a page
accessed w/o passing any params), tack "&& account_id.present?" onto
the conditional.
