Model.inc won't take BigDecimal

    • Type: Icon: Task Task
    • Resolution: Done
    • 3.0.2
    • Affects Version/s: None
    • Component/s: None

      I'm incrementing a field I've defined as BigDecimal:

      field :balance, type: BigDecimal, default: 0

      So I figured the most appropriate thing to do is convert the value to BigDecimal before passing it to #inc:
      def increment(amount)
      self.inc(:balance, amount.to_d * 100)
      end

      But I get the following error:

      NoMethodError:
      undefined method `bson_dump' for #<BigDecimal:29563f0,'0.1E6',9(36)>
