Preloading associations in GORM prevents the N+1 query problem by loading related records in bulk, reducing database round‑trips and improving performance.

To fix the N+1 query problem in GORM, use the Preload method to eagerly load associated records in bulk. This reduces database round-trips by fetching related data through minimal queries instead of executing a separate query for each parent record.
Loading nested associations in GORM requires using dot notation within the Preload method to fetch deep relationships. This approach allows you to specify paths to nested entities, ensuring all levels of related records are eagerly loaded.
You can filter associated records during GORM preloading by passing optional conditional functions to the Preload method. This allows you to apply specific query constraints to the related data being eagerly loaded, narrowing the result set.
You should switch to Joins instead of Preload for one-to-one relationships in GORM when you need to filter parent records based on related data. Joins combines the tables in a single query, which is more efficient for this specific filtering scenario.
Using clause.Associations in GORM triggers the bulk loading of all direct associations for a given model. It serves as an optional parameter in the Preload method to eagerly fetch all related records without manually specifying each relationship.
