Subquery has too many columns
When I change the *base_manager_name* and try to update the model an
exception is raised <http://pastebin.com/PNs4axGC>.
This is my code:
class ProdutoServicoManager(models.Manager):
def get_queryset(self):
expression = models.Sum(models.F('custounitario__valor') *
models.F('custounitario__quantidade'))
total_expr = models.ExpressionWrapper(expression,
output_field=models.DecimalField())
return super().get_queryset().annotate(custo_producao=total_expr)
class ProdutoServico(Base):
produto = models.BooleanField(default=True)
descricao = models.TextField()
objects = ProdutoServicoManager()
class Meta:
base_manager_name = 'objects'
I thought I had found the answer to this problem in issue 19513
<https://code.djangoproject.com/ticket/19513>, but it was already closed.
Apparently this error reappears when I try to annotate the base_manager.
Should I open a new issue?

Choices in DecimalField - django 1.8.
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! -- You received this message because you are subscribed to the Google Groups "Django users" group.

BinaryField on Django 1.6b4
I created a new project with a class with two fields, one type CharField and another type BinaryField. When I access the admin, only the field name appears. My class: class Arquivo(models.Model): nome = models.CharField(max_length=255) arquivo = models.BinaryField() def __unicode__(self): return self.nome Sorry if my english is not good. -- You received this message because you are subscribed to the Google Groups "Django users" group.
