Introducing the Django ORM Series: Mastering Django ORM from Beginner to Advanced
Greetings, fellow developers and Django enthusiasts! Today, I’m thrilled to announce the launch of a brand new blog series that will take you on a comprehensive journey through Django’s Object-Relational Mapping (ORM) system. Whether you’re just starting your Django adventure or you’re an experienced developer looking to deepen your Django knowledge, this series is tailor-made for you.
Why Django ORM?
Django, the popular Python web framework, has garnered immense praise for its simplicity, flexibility, and robustness. At the heart of its power lies the ORM system, which transforms the way we interact with databases. Instead of wrestling with raw SQL queries, Django ORM allows us to manipulate and query databases using Python objects and methods.
