How to pre-select dropdown on Django?

I already tried other posts with similar problems but the code I'm dealing with was made by a third party and I'm having some small problems. I simply cannot define one of the forms with the initial value I want. How to proceed?

class Livro(models.Model):
codigo = models.AutoField(primary_key=True)
nome = models.CharField("Nome", max_length=50, unique = True)
autor = models.CharField("Autor", max_length=50, unique = True)
edicao = models.CharField("Edição", max_length=30, unique = True)
disciplina = models.ForeignKey(Disciplina)
tipo = models.CharField("Tipo", max_length=20, choices = Choices.tipo)
ano = models.CharField("Ano", max_length=30, choices = Choices.ano)
situacao = models.CharField("Situação", max_length=30, choices = Choices.situacao, blank = True, null = True)
def __unicode__(self):
return self.nome

def cadastrar_livro(request):
form = LivroForm(request.POST or None)
if form.is_valid():
salvo =
salvo.situacao = "Ativado"
return HttpResponseRedirect('/principal')
return render_to_response('cadastrar_livro.html', locals(), context_instance = RequestContext(request))

and on

class Choices(models.Model):
tipo = (
('1', 'Seriado'),
('2', 'Único'),

ano = (
('1', '1º'),
('2', '2º'),
('3', '3º'),
('4', 'Único'),

situacao = (
('Ativado', 'Ativado'),
('Desativado', 'Desativado'),

I just need situacao to pre select Ativado but can't find any solutions to it. Need help thanks.


Did you try to set the default argument in the situacao field.

situacao = models.CharField("Situação", max_length=30, choices=Choices.situacao, default=Choices.situacao[1], blank=True, null=True)
