An example of an AI chatbot conversation about handling relationships in Django queries.
How do I handle relationships in Django queries?
In Django, you can handle relationships using the ORM. You can use methods like select_related and prefetch_related to optimize your queries.
Can you explain the difference between select_related and prefetch_related?
Sure! select_related is used for single-valued relationships (like ForeignKey) and performs a SQL join, while prefetch_related is used for multi-valued relationships (like ManyToMany) and executes separate queries.
When should I use each of them?
Use select_related when you need to access related objects in a single query, and prefetch_related when dealing with many-to-many relationships or when you want to minimize the number of queries.
