Create Objects in Django

This article explains what a model is and how to create objects using the create() method. We will see how to work the save() method in Django.

Create Objects Using the create() Method in Django

A model in Django is a class that represents a single table in a database. We could have each type of data in our application represented by its model.

Each model then maps to a single table in a database.

For example, if we have four models, articles, users, authors, and books, we would have four tables in a database. A single model maps each table.

Let’s see how to create objects of a model in the database.

We are going to use the Python shell to create new objects. We need to use the admin to ensure that we are at the root of our Django project.

Now, we are going to run another command. So when we run this command, all of the Django project stuff will work inside a Python interpreter.

We will see a normal Python interpreter when we hit Enter, but it is not because we can run the following command.

python shell

We have imported the Product model from the file. We can use our Product model in the current shell if we hit Enter.

from products.models import Product

We have built-in Django command to retrieve all objects from the defined model.


Now, we can see there is only one item, and that is because we only saved one.

<QuerySet[<Product: Product object (1)>]>

If we want to see more objects, we only need to create more objects using the following command.


Suppose our Product model has four fields. These four fields must pass in the create() method to create a new object.

Django Create Object - Example 1

Let’s create a new object by writing the following command.

Product.objects.create(title="New product",description="Another one", price=1222,summary="The best product")

After writing this command, when we hit the Enter, it will create a new object.

<Product: Product object (2)>

So now, if we try to retrieve all objects, we will see another newly created item.


Now, we can see the second item of the query list.

<QuerySet[<Product: Product object (1)>,<Product: Product object (2)>]>

When we go to the admin panel, we will see new objects there.

Now, we will look at using the save() method. Suppose we have the following code, and we need to save all fields of the defined model.

We need to pass all fields in our model class and create an object to save this using the save() method.

Django Create Object - Example 2

We defined the product_id in the above code, so now we can access the product using its ID. In the product_id, we set the primary_key equal to True.

The save() method works for two conditions meaning if the given product_id already exists in the database, the object will be updated with different field values.

If the save() method does not find the primary_key attribute set to True in product_id, or if the given ID does not exist in the database, it will produce an error. Using the Product.objects.create(), we will only be able to insert new objects.
