I try to chain material and categorie with django smart select but it does not work
What is wrong in my code ?
class Demande_Expertise(models.Model):
user = models.ForeignKey(User)
material = models.ForeignKey("Material")
categorie = ChainedForeignKey("material.Category",
chained_field="material",
chained_model_field="name",
show_all=False,
auto_choose=True)
droits_acces = models.CharField(_('val_champ'), max_length=150, choices = DROITS)
groupe = models.ForeignKey(Group, blank = True, null= True, default = None)
etat = models.CharField(_('val_champ'), max_length=150, choices = ETAT, default = '2')
class Category(models.Model):
name = models.CharField(_('name'), max_length=50)
slug = models.SlugField()
class Material(models.Model):
name = models.CharField(_('name'), max_length=50)
description = models.TextField(_('description'), blank=True)
slug = models.SlugField()
category = ChainedForeignKey(Category, verbose_name=_('category'),
chained_field="name",
chained_model_field="name",
show_all=False,
auto_choose=True)
created = models.DateField(_("creation date"), auto_now_add=True)
Try Django Clever Selects

I use it in my Django 1.6 project
Your structure is incorrect I am giving you an example that works
class Continent(models.Model):
name = models.CharField(max_length=255)
def __str__(self):
return self.name
class Country(models.Model):
continent= models.ForeignKey(Continent)
name = models.CharField(max_length=255)
def __str__(self):
return self.name
class City(models.Model):
continent= models.ForeignKey(Continent)
country= ChainedForeignKey(Country, chained_field="continent", chained_model_field="continent", show_all=False, auto_choose=True, sort=True)
name = models.CharField(max_length=255)
def __str__(self):
return self.name
class Neighborhood(models.Model):
continent= models.ForeignKey(Continent)
country= ChainedForeignKey(Country, chained_field="continent", chained_model_field="continent", show_all=False, auto_choose=True, sort=True)
name = models.CharField(max_length=255)
city= ChainedForeignKey(City, chained_field="country", chained_model_field="country", show_all=False, auto_choose=True, sort=True)
name = models.CharField(max_length=255)

I want to display the trainer for a course date. A course can have several dates and a different trainer can be used on each date. A trainer can have a different role on each course date. (Instructor, helper...)
How do I make the correct query? Are the models correct for this?

There are models, why after python manage.py makemigrations is created only by 1 field in migrations, how to fix it? I tried doing manage.py migrate --fake zero, and doing the migrations again, but nothing.The app is registered in settings.

Your fields should not end with a comma (,). If you add a trailing comma, it will wrap the field in a singleton tuple, and thus Django is then not able to detect the field:

please Guys Help me how auto select Patient Name IN Wardconfig when assign bed
Sorry for English
You can give the view you are using to add a WardConfig record a get_initial method. This assumes you are passing a patient_id kwarg in the URL:
def get_initial(self):
patient = get_object_or_404(Patient, pk=self.kwargs.get('patient_id'))
return {
'patient': patient,
}
