Original: GORM: Dev's Guide to Go's Most Popular ORM

Short summary

A walkthrough of GORM, Go's most popular ORM, covering setup, struct-based models, auto-migrations, CRUD operations, associations, and common gotchas. Key topics include connection pooling via db.DB(), soft deletes with gorm.DeletedAt, field-level constraint tags, and the limitation that AutoMigrate won't drop columns or change types, making it unsuitable as a sole production migration tool.

  • GORM wraps database/sql with struct models, auto-migrations, and a chainable query builder
  • AutoMigrate is safe for dev but teams should use golang-migrate or atlas for production schema changes
  • Connection pool settings must be configured via the underlying *sql.DB obtained through db.DB()
