Choices in DecimalField - django 1.8.

[Elton Pereira]

In the model below, using the Django admin, no matter what value I choose, it always displays the default value. But writes the correct value in the  database. Am I doing something wrong or is this a bug?

TENSAO_220 = Decimal(220)

TENSAO_110 = Decimal(110)

TENSOES = ((TENSAO_220, '220 volts'),

           (TENSAO_110, '110 volts'))

class Equipamento(models.Model):

    nome = models.CharField(max_length=128)

  tensao = models.DecimalField(max_digits=8,

                               decimal_places=3,

                               choices=TENSOES,

                               default=TENSAO_220)

Thanks!

In case anyone else ends up here, I've found that it's very sensitive to how you specify the Decimal, so in my example Decimal('20.00') worked but Decimal('20') and Decimal(20) did not.
