Like #find_by, except that if no record is found, raises an ActiveRecord::RecordNotFound error.

# File activerecord/lib/active_record/relation/finder_methods.rb, line 88
    def find_by!(arg, *args)
      where(arg, *args).take!
    rescue ::RangeError
      raise RecordNotFound.new("Couldn't find #{@klass.name} with an out of range value",
                               @klass.name, @klass.primary_key)
    end
