hey all I have a model which is as such: *in models.py*
class ConditionSet(models.Model): model_name = models.CharField(max_length= 50) model_attribute = models.CharField(max_length=50) operator = models.CharField(max_length=50, choices=OPERATORS) val = models.CharField(max_length=50,null=True,blank=True) evaluation = models.NullBooleanField(null=True, blank=True) def __str__(self): return self.model_attribute *in admin.py :* def get_all_models(): return [('.'.join([each._meta.app_label,each.__name__]),each.__name__) for each in [each.model_class() for each in ContentType.objects.filter(app_label__in=['products','productoptions','shoppingcart']) if each is not None] if each is not None] def get_attributes(): model_class = ContentType.objects.filter(app_label__in=['products','productoptions','shoppingcart'])[0].model_class() return [ (each.name,each.name) for each in model_class._meta.fields ] class ConditionSetAdminForm(forms.ModelForm): def __init__(self,*args,**kwargs): super(ConditionSetAdminForm, self).__init__(*args,**kwargs) self.fields['model_name'] = forms.ChoiceField(required=True, label='Model Name', choices=get_all_models()) self.fields['model_attribute'] = forms.ChoiceField(required=True, label='Model Attribute', choices=get_attributes()) class Meta: model = ConditionSet class ConditionSetAdmin(admin.ModelAdmin): form = ConditionSetAdminForm admin.site.register(ConditionSet, ConditionSetAdmin ) model_attribute has an initial set of choices, populated by get_attributes(). When a user selects model_name in admin, i make a json call to get options and populate model_attribute options , but when i try to save it, i get "select a valid choice. xyz_attribute_name is not one of the available choices." I understand the problem is the choices for this field are still the one assigned to it in beginning, how should I fix it ? -- You received this message because you are subscribed to the Google Groups "Django users" group.
