How do I make an auto increment integer field in Django?

Question

I am making an Order model for a shopping cart and I need to make a field that auto increments when the order is made:

class Order(models.Model)         


        

Answer 1

In django with every model you will get the by default id field that is auto increament. But still if you manually want to use auto increment. You just need to specify in your Model AutoField.

class Author(models.Model):
    author_id = models.AutoField(primary_key=True)

you can read more about the auto field in django in Django Documentation for AutoField
