django smart-select

Hi all,

I'm so sorry for this e-mail. May be you answered similar questions
many times. But I really need your help to learn how it's works.

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 model

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=5
0)
available_color = ChainedForeignKey(
Cars,
chained_field="car_model",
chained_model_field="car_colors",
show_all=False,
auto_choose=True
)

def __unicode__(self):
return self.car_barcode
My admin.py 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.id,csc.car_colors) for csc in Cars.objects.all()]

class CarsDataAdmin(admin.ModelAdmin):
form = CarsDataAdminForm

admin.site.register(CarsData,CarsDataAdmin)

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!
