Django - Choice Field None:

Question

I’m having trouble making one Choice Yeah, when he goes by form, the field returns only "" or None. Already if I put widget=RadioSelect, it returns the correct numbering.

Model:

ORDER_CHOICES = (
    (1, "1° Prêmio"),
    (2, "2° Prêmio"),
    (3, "3° Prêmio"),
    (4, "4° Prêmio"),
    (5, "5° Prêmio"),
)

order = models.IntegerField(
    'Premiação', choices=ORDER_CHOICES,
    db_column='order', blank=True)

Forms:

class Selectpremiumform(Forms.Modelform):

order = forms.ChoiceField(choices=SelectPremium.ORDER_CHOICES,
                          widget=forms.RadioSelect)
class Meta:
    model = SelectPremium
    fields = ['order']
