SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Applications often need to guarantee that data stored in the database obeys business rules. Without constraints, invalid or inconsistent records can be inserted, leading to bugs and data corruption.

Core Features & Use Cases

  • Define CHECK constraints directly in GORM model tags to validate column values.
  • Configure foreign key actions (ON UPDATE, ON DELETE) using the constraint tag.
  • Optionally disable automatic foreign‑key creation during migration for bulk data loads or legacy databases.

Quick Start

Use the gorm-constraints skill to add a CHECK constraint on the age field of the User model.

FAQPage Schema
How do I add a CHECK constraint in GORM to validate column values?

Add a CHECK constraint in GORM by defining validation rules directly in your model tags. This enforces data integrity during auto-migration by ensuring column values meet specified business rules before records are inserted.

Can I configure foreign key actions like ON DELETE in GORM models?

Configure foreign key actions in GORM using the constraint tag to specify ON UPDATE and ON DELETE rules. This manages relational actions automatically during auto-migration to maintain referential integrity across your database tables.

How do I disable foreign key creation during GORM auto-migration?

Disable foreign key creation during GORM auto-migration through optional configuration settings. This supports bulk data loads and legacy database integration by preventing the automatic generation of foreign key constraints.

What is the best way to enforce data integrity in a Go application using GORM?

Enforce data integrity in Go applications using GORM by defining database constraints like CHECK and foreign key rules within model tags. This validates column values and manages relational actions directly during database migration.

Why use database constraints instead of application-level validation in GORM?

Database constraints in GORM prevent invalid or inconsistent records from being inserted at the database level. This guarantees data integrity and avoids data corruption bugs that application-level validation alone might miss.

When should I disable foreign key constraints in GORM?

Disable foreign key constraints in GORM when migrating large datasets or working with legacy databases. This optional configuration prevents automatic foreign key generation, facilitating bulk data loads without relational enforcement overhead.
