💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill provides expert guidance for using SeaORM 2.0, helping developers navigate its new patterns and avoid common pitfalls inherited from SeaORM 1.0, ensuring efficient and correct database interactions in Rust applications.

Core Features & Use Cases

  • New Entity Format: Understand the #[sea_orm::model] macro and relation definitions directly on structs.
  • Strongly-Typed Columns: Leverage COLUMN constants for compile-time safety.
  • Entity Loader API: Efficiently fetch related data to prevent N+1 query problems.
  • Nested ActiveModel: Persist complex object graphs with ease.
  • Use Case: When defining new entities, setting up relationships, or optimizing database queries in a Rust project using SeaORM 2.0, this skill provides the necessary patterns and best practices.

Quick Start

Use the sea-orm-2 skill to define a new user entity with a one-to-many relationship to posts.

FAQPage Schema
How do I define entities with the new SeaORM 2.0 model macro?

SeaORM 2.0 introduces the `#[sea_orm::model]` macro to define entities and relations directly on structs. This new format shifts to an entity-first workflow, replacing older SeaORM 1.0 patterns and integrating with the Schema Registry.

What's the best way to prevent N+1 queries when fetching related data in SeaORM?

Use the Entity Loader API in SeaORM 2.0 to efficiently fetch related data and prevent N+1 query problems. This API optimizes database interactions by batching related entity loads during async workflows.

How do I persist complex object graphs with nested ActiveModel in Rust?

Use the nested ActiveModel builder in SeaORM 2.0 to persist complex object graphs with ease. This pattern simplifies saving related entities together within async Rust database interactions.

Does SeaORM 2.0 support strongly-typed columns for compile-time safety?

Yes, SeaORM 2.0 supports strongly-typed columns via `COLUMN` constants for compile-time safety. This feature ensures type correctness in database queries and prevents runtime type errors during async operations.

What SeaORM 1.0 anti-patterns should I avoid when upgrading to Rust async ORM 2.0?

SeaORM 2.0 addresses anti-patterns from SeaORM 1.0 by introducing the `#[sea_orm::model]` macro, strongly-typed `COLUMN` constants, and the Entity Loader API. Adopt these new patterns to avoid common pitfalls and ensure efficient database interactions.

Why use the Entity Loader API for async database queries in Rust?

The Entity Loader API in SeaORM 2.0 optimizes async database queries by efficiently fetching related data. This prevents N+1 query problems and streamlines complex data retrieval workflows in Rust applications.
