Thank you Collin, I tried that before posting in this group but the
same thing happened: I get no errors when saving but Tags still remain
not asociated with Receta.
class Receta(models.Model):
....
def save(self):
from django.template.defaultfilters import slugify
tags = self.etiquetas_text.split(',')
super(Receta, self).save()
for tag in tags:
etiq, created =
Tag.objects.get_or_create(nombre=tag,slug=slugify(tag))
self.etiquetas.add(etiq)
Anyone knows where the problem is?
Thanks.
