Re: unique_together does not work in django 2.0
Hello, Problem solved. For it to work I have to put the META class between the silo class and the method.

unique_together does not work in django 2.0
Hello,
I have the following class:
==
class Silo(models.Model):
nave = models.ForeignKey(Nave, on_delete=models.CASCADE)
codSil = models.CharField(
'Código Silo', db_index=True, max_length=2, default='01')
notas = models.TextField(null=True, blank=True)
def __str__(self):
return "%s %s" % (self.nave, self.codSil)
class Meta:
order_with_respect_to = 'nave'
unique_together = ('nave', 'codSil')
But the option unique_together does not work because duplicate values
exist in the SQLite database for nave and codSil.
To solve it, I have to create the index nave + codSil by hand in the SQLite
database ???
Thank you

Using the ModelAdmin.inlines class, there is no DELETE button
Good Morning,
I'm customizing the ModelAdmin class inlines attribute. The code is this.
class NaveInline(admin.TabularInline):
model = Nave
fields = ['codigoNave', 'nave', 'tipoPuesta']
ordering = ['codigoNave']
extra = 1
class GranjaAdmin(admin.ModelAdmin):
fieldsets = [
(None, {'fields': [('codigoGranja', 'granja'), ('empresa',
'tipoGranja'), ('regimen')]}),
('Datos adicionales', {'fields': [('direccion', 'localidad',
'codigoPostal',
'provincia', 'region', 'pais', 'telefonoPrincipal',
'telefonoMovil',
'fax', 'email', 'ceence','cea', 'maquina',
'clasificacionZootecnica',
'formaDeCria', 'notas')], 'classes': ['collapse']}),
]
inlines = [NaveInline]
. . . . . .
Everything works perfectly, I can add granjas / naves, edit granjas /
naves, and clear granjas. . but I can not do it is to delete naves that in
this case are the lines (inlines).
I do not get any errors, I can see the line selection check but the line
deletion button DOES NOT APPEAR.
Thanks for your help,
Fernando

Re: Error following django's documentation 2.0
Good morning, I think the error comes from making modifications to django's settings. I started the project again and now the django shell works. Thanks for your interest !!!

Error following django's documentation 2.0
Hello everyone, I'm learning django. I am in the official documentation of django link: *https://docs.djangoproject.com/en/2.0/intro/overview/* After creating the model and doing the migrate I go to the section called *Enjoy the free API* to test in the python terminal and I get an error when executing the *import*, it says that it can not find the module. *The only difference with the documentation* is that I am executing it from a *virtualenv*. it can be fixed ?
