What are the best practices for using Django ORM?
Some best practices include using select_related and prefetch_related for optimization, avoiding raw SQL when possible, and using model managers for custom queries.
Can you explain how select_related and prefetch_related work?
Sure! select_related is used for single-valued relationships and performs a SQL join, while prefetch_related is for multi-valued relationships and executes separate queries.
How can I improve query performance in Django ORM?
You can improve performance by using indexing, limiting the number of fields retrieved, and caching query results.
Are there any common pitfalls to avoid with Django ORM?
Yes, common pitfalls include N+1 query problems, not using transactions for bulk operations, and overusing raw SQL.
