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!
