Async Relying on [SQLx](https://github.com/launchbadge/sqlx), SeaORM is a new library with async support from day 1. 2. Dynamic Built upon [SeaQuery](https://github.com/SeaQL/sea-query), SeaORM allows you to build complex queries without 'fighting the ORM'. 3. Testable Use mock connections to write unit tests for your logic. 4. Service Oriented Quickly build services that join, filter, sort and paginate data in APIs. ## A quick taste of SeaORM ### Entity ```rust use sea_orm::entity::prelude::*; #[derive(Clone, Debug, PartialEq, DeriveEntityModel)] #[sea_orm(table_name = "cake")] pub struct Model { #[sea_orm(primary_key)] pub id: i32, pub name: String, } #[derive(Copy, Clone, Debug, EnumIter, DeriveRelation)] pub enum Relation { #[sea_orm(has_many = "super::fruit::Entity")] Fruit, } impl Related for Entity { fn to() -> RelationDef { Relation::Fruit.def() } } ``` ### Select ```rust // find all models let cakes: Vec = Cake::find().all(db).await?; // find and filter let chocolate: Vec = Cake::find() .filter(cake::Column::Name.contains("chocolate")) .all(db) .await?; // find one model let cheese: Option = Cake::find_by_id(1).one(db).await?; let cheese: cake::Model = cheese.unwrap(); // find related models (lazy) let fruits: Vec = cheese.find_related(Fruit).all(db).await?; // find related models (eager) let cake_with_fruits: Vec<(cake::Model, Vec)> = Cake::find().find_with_related(Fruit).all(db).await?; ``` ### Insert ```rust let apple = fruit::ActiveModel { name: Set("Apple".to_owned()), ..Default::default() // no need to set primary key }; let pear = fruit::ActiveModel { name: Set("Pear".to_owned()), ..Default::default() }; // insert one let pear = pear.insert(db).await?; // insert many Fruit::insert_many([apple, pear]).exec(db).await?; ``` ### Update ```rust use sea_orm::sea_query::{Expr, Value}; let pear: Option = Fruit::find_by_id(1).one(db).await?; let mut pear: fruit::ActiveModel = pear.unwrap().into(); pear.name = Set("Sweet pear".to_owned()); // update one let pear: fruit::Model = pear.update(db).await?; // update many: UPDATE "fruit" SET "cake_id" = NULL WHERE "fruit"."name" LIKE '%Apple%' Fruit::update_many() .col_expr(fruit::Column::CakeId, Expr::value(Value::Int(None))) .filter(fruit::Column::Name.contains("Apple")) .exec(db) .await?; ``` ### Save ```rust let banana = fruit::ActiveModel { id: NotSet, name: Set("Banana".to_owned()), ..Default::default() }; // create, because primary key `id` is `NotSet` let mut banana = banana.save(db).await?; banana.name = Set("Banana Mongo".to_owned()); // update, because primary key `id` is `Set` let banana = banana.save(db).await?; ``` ### Delete ```rust // delete one let orange: Option = Fruit::find_by_id(1).one(db).await?; let orange: fruit::Model = orange.unwrap(); fruit::Entity::delete(orange.into_active_model()) .exec(db) .await?; // or simply let orange: Option = Fruit::find_by_id(1).one(db).await?; let orange: fruit::Model = orange.unwrap(); orange.delete(db).await?; // delete many: DELETE FROM "fruit" WHERE "fruit"."name" LIKE 'Orange' fruit::Entity::delete_many() .filter(fruit::Column::Name.contains("Orange")) .exec(db) .await?; ``` ## Learn More 1.
