Hi, I'm new with Django and in this Groups; I have the next models and
question
class Empresa(models.Model):
usuario = models.ForeignKey(User)
empresa = models.CharField(max_length=100, unique=True)
slogan = models.TextField()
logotipo = models.ImageField(upload_to='logos')
descripcion = models.TextField()
compra_minima = models.FloatField(verbose_name='Compra Mínima')
costo_envio = models.FloatField(verbose_name='Costo de Envío')
def __unicode__(self):
return self.empresa
class Sucursal(models.Model):
empresa = models.ForeignKey(Empresa)
direccion = models.CharField(max_length=200, null=False)
estado = models.CharField(max_length=30)
municipio = models.CharField(max_length=30)
def __unicode__(self):
return self.direccion
class Platillo(models.Model):
empresa = models.ForeignKey(Empresa)
categoria = models.ForeignKey(Categoria_platillo)
nombre_platillo = models.CharField(max_length=100, null=False, blank=False,
verbose_name='Nombre del Platillo')
fotografia = models.ImageField(upload_to='platillos',
verbose_name='Fotografía')
descripcion = models.TextField()
precio = models.FloatField()
dia_existencia = models.CharField(max_length=150)
fecha_publicacion = models.DateTimeField(auto_now=True)
tags = models.CharField(max_length=100)
estatus = models.BooleanField(null=False, default=True)
def __unicode__(self):
return self.nombre_platillo
class Horario(models.Model):
empresa = models.ForeignKey(Empresa)
dia = models.CharField(max_length=15)
hora_abre = models.CharField(max_length=10)
hora_cierra = models.CharField(max_length=10)
def __unicode__(self):
return self.hora_abre
Now, I want to create a result like this:
{Empresa1, Sucursal1, Platillo1, Horario1}, {Empresa1, Sucursal1,
Platillo2, Horario1}, {Empresa2, Sucursal1, Platillo1, Horario1}...
I use "select_related()" method, but I can't do it
