Simplify working with UUID primary keys in Rails console

fish.rb

class ActiveRecord::Base
  # Find a record by UUID primary key prefix
  #
  # Example:
  # > User.fish "1245"
  # # User Load (0.3ms)  SELECT  "users".* FROM "users" WHERE ("users"."id" BETWEEN '12450000000000000000000000000000' AND '1245ffffffffffffffffffffffffffff') LIMIT $1  [["LIMIT", 2]]
  # => #<User id: "12451304-761d-4e1d-8281-40aa6213b633", name: "josh">
  def self.fish(partial_id)
    return find(partial_id) unless partial_id.is_a?(String)
    scrubbed = partial_id.gsub(/[^a-fA-F0-9]/,  "")
    missing_length = 32 - scrubbed.length
    raise "Invalid UUID: #{scrubbed}" if missing_length < 0
    return find(partial_id) if missing_length == 0

    lower = "#{scrubbed}#{'0' * missing_length}"
    upper = "#{scrubbed}#{'f' * missing_length}"
    matches = where(id: (lower..upper)).take(2)
    raise "Ambiguous id prefix: #{scrubbed}. Be more specific" if matches.length > 1
