Performance & Optimization
Snippets for optimizing Django applications, covering caching, query optimization, database indexing, and performance tuning for scalable projects.
Enable Query Debugging
Log SQL queries executed by Django ORM for optimization.
Use select_related for Optimization
Reduce queries for foreign key relationships using select_related.
Database Indexing Example
Add indexes to model fields for faster queries.
Use prefetch_related for Many-to-Many
Optimize many-to-many queries using prefetch_related.
Using cache_page Decorator

Database Query Optimization with only()
Retrieve only specific fields from the database with only().
Bulk Create for Performance
Insert multiple objects efficiently using bulk_create().
Bulk Update for Performance
Update multiple objects efficiently using bulk_update().
Optimize Query Counts with count()
