Admin : Select category -> show subcategory

[martyn]

Hi,

I've created a simple product model :

class Produit(models.Model):
        nom = models.CharField(maxlength=200)
        slug = models.SlugField(prepopulate_from=('nom',))
        description = models.TextField(blank=True)
        published = models.BooleanField(default=True)
        prix_ht = models.DecimalField(max_digits=30, decimal_places=2)
        famille = models.ForeignKey('Famille')
        sous_categorie = models.ForeignKey('SousCategorie')
        clic

    class Admin:
        pass

I've got also Category and SubCategory :


class Categorie(models.Model):
        nom = models.CharField(maxlength=200)
        slug = models.SlugField(prepopulate_from=('nom',))
    class Admin:
        pass

    def __str__(self):
        return self.nom

class SousCategorie(models.Model):
        nom = models.CharField(maxlength=200)
        slug = models.SlugField(prepopulate_from=('nom',))
        categorie = models.ForeignKey('Categorie')
    class Admin:
        pass

    def __str__(self):
        return self.nom



Is there a way in django admin, in the Product form, to select the
category, then the subcategories of this category only are shown in
the select list.

Thanks a lot
