Passing kwargs into get_or_create method in Django

Question

I have a model with a custom save function, where I want to perform certain functions based on a condition like this:

class ClassName(models.Model):

    def save(self, *args, **kwargs):
        reindex =  **kwargs.pop("reindex")

        super().save(*args, **kwargs)

        if reindex:
            People.objects.create()

Now inside a task I want to call the following:

kwargs = { "reindex": False}
ClassName.objects.get_or_create(**kwargs)

When it does a create, it obviously runs the save function, but it's giving me an error saying reindex is not a field . I have been researching it for a while now and can't figure out what to do. Maybe someone can point me in the right direction.

I just want to pass in an argument into the get_or_create , so that I can conditionally perform a certain function in the save method.

Answer 1

When you do

kwargs = { "reindex": False}
ClassName.objects.get_or_create(**kwargs)

it is actually equivalent to

ClassName.objects.get_or_create(reindex=False)

Thus, since reindex appears not to be a field defined in the model ClassName , you get an error.

BTW, beyond things which appear erroneous, eg reindex = **kwargs.pop("reindex") , you should define reindex as one of the fields of your model. But I admit that I answer blindly, because to me, your class definition cannot work like so. If one assumes that reindex is an integer field, you could do

 class ClassName(models.Model): reindex = models.IntegerField(null=True) def save(self, *args, **kwargs): super(ClassName, self).save(*args, **kwargs) if "reindex" in kwargs: People.objects.create()
