40. How to override save behaviour for Django admin?

ModelAdmin has a save_model method, which is used for creating and updating model objects. By overriding this, you can customize the save behaviour for admin.

The Hero model has the following field.:

added_by = models.ForeignKey(settings.AUTH_USER_MODEL,
        null=True, blank=True, on_delete=models.SET_NULL)

If you want to always save the current user whenever the Hero is updated, you can do.:

def save_model(self, request, obj, form, change):
    obj.added_by = request.user
    super().save_model(request, obj, form, change)
