How to automatically fill an empty model field with a link?

Question

Django

There is this model:

class Vote(models.Model):


  record = models.OneToOneField(Record)

  voted_by = models.ForeignKey(UserProfile)

How to automatically populate the record field? It is necessary that the record field be filled in automatically by already created objects of the Record class.

Answer 1

default=1
Or write a signal

Answer 2

If you need to add a connection when creating a model Vote, then you can overload the methodsave()

class Vote(models.Model):
    
    def save(self, *args, **kwargs):
        #Проверяем, что объекта еще нет в базе
        if self.pk is None:
            record = Record.objects.create(#заполняете нужные поля)
            self.record = record
        super(Vote, self).save(*args, **kwargs)

It is not entirely clear from the question what exactly is needed, if you need an already created object Record, you can simply take it from the database, and not create a new one.
