There is a little problem with third-level(?) models (or many times related models) in admin area with django-smart-selects plugin. I don't know what does matter :)

This my colors models

from django.db import models

class Colors(models.Model):
color_name = models.CharField(max_length=50)

def __unicode__(self):
    return self.color_name

This my Cars models

from django.db import models

class Cars(models.Model):
car_model = models.CharField(max_length=50)
car_colors = models.ManytoManyField(Colors, related_name='Car Colors')

def __unicode__(self):
    return self.car_model

O.K. Let's see my CarsData Model.

This my CarsData models

from django.db import models

class CarsData(models.Model):
car_barcode= models.CharField(max_length=50)
available_color = ChainedForeignKey(

def __unicode__(self):
    return self.car_barcode

My looks like that:

from django.contrib import admin
from django import forms
from myapp.models import *

class CarsDataAdminForm(forms.ModelForm):

class Meta:
    model = CarsData
def __init__(self, *arg, **kwargs):
    super(CarsDataAdminForm, self).__init__(*arg, **kwargs)
    self.fields['available_color'].choices =  [(,csc.car_colors) for csc in Cars.objects.all()]

class CarsDataAdmin(admin.ModelAdmin):
form = CarsDataAdminForm,CarsDataAdmi
Is there anyway to show in the ChoiceField 'just' color_name field datas? I see just car_model because i have to set it :

def unicode(self):
return self.car_model
Can you please give me an example?

Many thanks!

Please next time if you write something don't give it. Because who uses this plugin also waiting a support. No support, sucks!

I have this error too.
I would put a report that problem, but it seems no help.
Well, i will put.

Here too.

My code in models is :

class Person(models.Model):
    name = models.CharField(max_length=20, help_text="Tipo de Persona que se inscribe", verbose_name="Nombre del Tipo")

    class Meta:
        verbose_name = "Tipo de Persona"

    def __str__(self):

class MemberShip(models.Model):
    title = models.CharField(max_length=255, help_text="Nombre del tipo de afiliación.",verbose_name="Título")
    #type_person = models.CharField(max_length=255, choices=AFFILIATION_PERSON_TYPE, verbose_name='Tipo de Persona',)
    type_person = models.ForeignKey(Person, verbose_name="Tipo de Persona", related_name="membership")
    descript = models.CharField(max_length=500, help_text="Descripción del tipo de afiliación.", verbose_name="Descripción")
    value = models.DecimalField(decimal_places=2, max_digits=10, verbose_name='Cuota', help_text="Cuota de afiliación.")

    class Meta:
        #description = 'Modelo Membresía'
        verbose_name = "Membresía"

    def __str__(self):
        return self.title

class Affilliation(models.Model):
    person = models.ForeignKey(Person, verbose_name="Tipo de Persona", related_name="persona")
    affiliation = ChainedForeignKey(

And my admin code is very simple:

class AffilliationAdmin(admin.ModelAdmin):
    fieldsets = [
        ('Afiliación', {
            'fields': ['person', 'affiliation', 'affiliates', 'is_active'],
        ('Fechas', {
            'fields': ['date_in', 'date_renew'],
    list_display = ('affiliation', 'affiliates', 'is_active', 'date_prein', 'date_in', 'date_renew', 'date_end')
    list_filter = ('affiliation', 'affiliates', 'is_active')
    list_editable = ('affiliation',)
    search_fields = ('affiliation', 'affiliates', 'is_active', 'date_in',)

    def date_end(self):
        return self.date_in + timedelta(days=365)

    date_end.short_description = "Fecha de Expiración"
    date_end.allow_tags = True, AffilliationAdmin)

As you can see all is well, but, if i try use ChainedField, well, in the django-admin i give this:

In Juridica i have four MemberShips child's, but in this select box they aren't.

In a form this field works?
