In this course, you are going to learn various concepts related to Django ORM. Django ORM is a core and powerful component of the Django Framework. Using this ORM, we can simplify the database-related operations in an object-oriented way. In this course, you are going to learn how to model for a Blogging project. The agenda is not to make a blogging site, but to teach you about what can you do with the Django ORM and what Django ORM has to offer, to make your project performant. Then, we will deep dive into querying the database which is the most important section of this course. Without knowing how to query the database, you are never going to feel confident as a Django developer. So, you will be taught different things about queryset API provided by Django ORM in order to interact with the databases. You are going to learn various methods which are used in CRUD operations. Like order_by, values, only, defer, select_related, prefetch_related, Q objects, F expressions, raw SQL query, and many more.
