# SeaORM

Inspired by ActiveRecord, Eloquent and TypeORM, SeaORM aims to provide you an intuitive and ergonomic
API to make working with databases in Rust a first-class experience.

```markdown
This is a preview of SeaORM, and is not yet released.
```

## Features

1. Async

Relying on SQLx, SeaORM is a new library with async support from day 1.

2. Dynamic

Built upon SeaQuery, 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

### Select
```rust
// find all models
let cakes: Vec<cake::Model> = Cake::find().all(db).await?;

// find and filter
let chocolate: Vec<cake::Model> = Cake::find()
    .filter(cake::Column::Name.contains("chocolate"))
    .all(db)
    .await?;

// find one model
let cheese: Option<cake::Model> = Cake::find_by_id(1).one(db).await?;
let cheese: cake::Model = cheese.unwrap();

// find related models (lazy)
let fruits: Vec<fruit::Model> = cheese.find_related(Fruit).all(db).await?;

// find related models (eager)
let cake_with_fruits: Vec<(cake::Model, Vec<fruit::Model>)> = 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 res: InsertResult = Fruit::insert(pear).exec(db).await?;

println!("InsertResult: {}", res.last_insert_id);

// insert many
Fruit::insert_many(vec![apple, pear]).exec(db).await?;
```
### Update
```rust
use sea_orm::sea_query::{Expr, Value};

let pear: Option<fruit::Model> = 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::ActiveModel = Fruit::update(pear).exec(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::Null))
    .filter(fruit::Column::Name.contains("Apple"))
    .exec(db)
    .await?;

```
### Save
```rust
let banana = fruit::ActiveModel {
    id: Unset(None),
    name: Set("Banana".to_owned()),
    ..Default::default()
};

// create, because primary key `id` is `Unset`
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
let orange: Option<fruit::Model> = Fruit::find_by_id(1).one(db).await?;
let orange: fruit::ActiveModel = orange.unwrap().into();

// delete one
fruit::Entity::delete(orange).exec(db).await?;
// or simply
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?;
