为在 Django 管理面板中创建的对象保存创建者

Question

I want to create a few objects directly in Django's admin panel, and in that object automatically save the username of the administrator that have been creating it.

Any suggestions of how to do this in the easiest way?

Cheers,

Peter

class UserMessage(models.Model):
    reciever_id = models.OneToOneField(
        User,
        on_delete=models.CASCADE,
        primary_key=True,
    )
    heading = models.CharField(max_length=60)
    message = models.TextField(blank=True)
    time_created = models.DateTimeField(auto_now_add=True)

    creator_id = models.ForeignKey(User)

Answer 1

You need to add a save_model method to your model admin:

def save_model(self, request, obj, form, change):
    if not obj.creator_id:  # if obj does not have a creator
        obj.creator_id = request.user
    super().save_model(request, obj, form, change)
