Django Admin - Change field model and automatically update another model

Well, I have a VagasUsuarios model and a Questionario model. I would like that when I updated the Questionario.pontuacao_questionario field via django admin, my other VagaUsuarios.pontuacao_vaga field would be updated as well. Is there a way to do this?

thanks for listening =)

My Models:

class Questionario(models.Model):
    usuario                 = models.ForeignKey(Contas, on_delete=models.CASCADE)
    [...]
    pontuacao_questionario  = models.DecimalField(max_digits=5, decimal_places=2, null=True, blank=True,verbose_name="Pontuacao do Questionário")

class VagasUsuarios(models.Model):
    usuario                 = models.ForeignKey(Contas, on_delete=models.CASCADE)
    [...]
    pontuacao_vaga          = models.DecimalField(max_digits=5, decimal_places=2, verbose_name="Pontuacao da Vaga")

You could do this with signals.

Example:

from django.db.models.signals import post_save
from django.dispatch import receiver
from myapp.models import Questionario, VagasUsuarios


@receiver(post_save, sender=Questionario)
def my_handler(sender, instance, **kwargs):
    obj = VagasUsuarios.objects.get(...)
    obj.pontuacao_vaga = instance.pontuacao_questionario
    obj.save()

Another is to override the save() (or rather clean()) method of your model and when it gets updated to fetch all the relevant VagasUsuarios-objects you want to update and update them.

Note on clean(): You got to call the clean-method yourself unless you are using the Django admin.
