I've been trying doing this:
class ArticuloTallaInline(admin.TabularInline):
model = Articulo_Talla
extra = 0
def get_formset(self, request, obj=None, **kwargs):
self.padre = obj
return super(ArticuloTallaInline, self).get_formset(request,
obj,
**kwargs)
def formfield_for_foreignkey(self, db_field, request, **kwargs):
print self.padre.tallaje
if db_field.name == "talla":
kwargs["queryset"] = Talla.objects.filter(tallaje=1)
return super(ArticuloTallaInline,
self).formfield_for_foreignkey(db_field, request, **kwargs)
It shows me value of tallaje in parent form but I got an Exception
Value: 'NoneType' object has no attribute 'tallaje'
My idea is do something like this: kwargs["queryset"] =
Talla.objects.filter(tallaje=self.padre.tallaje) but it doesn't work.
Thanks.
