What is CRUD in Django?

CRUD in the context of Django, a popular Python web framework, refers to the four fundamental operations that can be performed on a database or a data model. These operations are Create, Read, Update, and Delete, and they correspond to the basic functionalities needed to manage data in a web application.

Here's what each of the CRUD operations represents in Django:

Create (C):

Create operation involves adding new records or data entries to a database. In Django, this is typically achieved through the use of model forms and the create() method or the save() method on a model instance.

Read (R):

Read operation is about retrieving and displaying data from the database. In Django, you can use the Django Object-Relational Mapping (ORM) to perform queries and retrieve data from the database, often using the all(), filter(), and get() methods on model classes.

Update (U):

Update operation allows you to modify or edit existing data in the database. In Django, this is done by fetching an existing record from the database, making changes, and then saving it back to the database using the save() method.

Delete (D):

Delete operation is used to remove data records from the database. In Django, you can delete records by calling the delete() method on a model instance or using the delete() method on a QuerySet.

Conclusion

Django simplifies the implementation of these CRUD operations by providing a powerful and high-level Python ORM, making it easier for developers to work with databases and data models. In addition to this, Django's built-in forms and views also facilitate the creation and manipulation of data, enabling developers to quickly build robust web applications with database functionality. Django-related interviews, it's essential to be well-versed in Django's ORM and to anticipate and answer Django interview questions confidently and effectively. This knowledge is a valuable asset for aspiring web developers and those looking to strengthen their careers in the field.
