## 1.0.1 - 2024-08-26

### New Features

* Added `ConnectOptions::connect_lazy` for creating DB connection pools without establishing connections up front https://github.com/SeaQL/sea-orm/pull/2268

### Breaking Changes

* Changed `ProxyDatabaseTrait` methods to async. It's a breaking change, but it should have been part of the 1.0 release.
    The feature is behind the feature guard `proxy`, and we believe it shouldn't impact majority of users.

#[derive(DerivePartialModel, FromQueryResult)]
#[sea_orm(entity = "Cake")]
struct PartialCake {
    name: String,
    #[sea_orm(
        from_expr = r#"SimpleExpr::FunctionCall(Func::upper(Expr::col((Cake, cake::Column::Name))))"#
    )]
    name_upper: String,
}

assert_eq!(

        .to_string(),
    r#"SELECT "cake"."name", UPPER("cake"."name") AS "name_upper" FROM "cake""#
);
```

    cake.into_active_model().insert(db).await
        .expect_err("Insert a row with duplicated primary key")
        .sql_err(),
    Some(SqlErr::UniqueConstraintViolation(_))
));

assert!(matches!(
    fk_cake.insert(db).await
        .expect_err("Insert a row with invalid foreign key")
        .sql_err(),
    Some(SqlErr::ForeignKeyConstraintViolation(_))
));
```
* Added `Select::find_with_linked`, similar to `find_with_related`: https://github.com/SeaQL/sea-orm/pull/1728, https://github.com/SeaQL/sea-orm/pull/1743
```rust
fn find_with_related<R>(self, r: R) -> SelectTwoMany<E, R>
    where R: EntityTrait, E: Related<R>;
fn find_with_linked<L, T>(self, l: L) -> SelectTwoMany<E, T>
    where L: Linked<FromEntity = E, ToEntity = T>, T: EntityTrait;

// boths yields `Vec<(E::Model, Vec<F::Model>)>`
```
* Added `DeriveValueType` derive macro for custom wrapper types, implementations of the required traits will be provided, you can customize the `column_type` and `array_type` if needed https://github.com/SeaQL/sea-orm/pull/1720
```rust
#[derive(DeriveValueType)]
#[sea_orm(array_type = "Int")]
pub struct Integer(i32);

#[derive(DeriveValueType)]
#[sea_orm(column_type = "Boolean", array_type = "Bool")]
pub struct Boolbean(pub String);

#[derive(DeriveValueType)]
pub struct StringVec(pub Vec<String>);
```

```rust
#[derive(DeriveDisplay)]
enum DisplayTea {
    EverydayTea,
    #[sea_orm(display_value = "Breakfast Tea")]
    BreakfastTea,
}
assert_eq!(format!("{}", DisplayTea::EverydayTea), "EverydayTea");
assert_eq!(format!("{}", DisplayTea::BreakfastTea), "Breakfast Tea");
```
* Added `UpdateMany::exec_with_returning()` https://github.com/SeaQL/sea-orm/pull/1677
```rust
let models: Vec<Model> = Entity::update_many()
    .col_expr(Column::Values, Expr::expr(..))
    .exec_with_returning(db)
    .await?;
```
* Supporting `default_expr` in `DeriveEntityModel` https://github.com/SeaQL/sea-orm/pull/1474
```rust
#[derive(DeriveEntityModel)]
#[sea_orm(table_name = "hello")]
pub struct Model {
    #[sea_orm(default_expr = "Expr::current_timestamp()")]
    pub timestamp: DateTimeUtc,
}

    CakeBaker,
    #[sea_orm(entity = "super::cake::Entity")]
    Cake,
}
```
* Added [`seaography_example`](https://github.com/SeaQL/sea-orm/tree/master/examples/seaography_example)

assert_eq!(migrations.len(), 5);

let migration = migrations.get(0).unwrap();
assert_eq!(migration.name(), "m20220118_000002_create_fruit_table");
assert_eq!(migration.status(), MigrationStatus::Pending);
```
* The `postgres-array` feature will be enabled when `sqlx-postgres` backend is selected https://github.com/SeaQL/sea-orm/pull/1565
* Replace `String` parameters in API with `Into<String>` https://github.com/SeaQL/sea-orm/pull/1439
    * Implements `IntoMockRow` for any `BTreeMap` that is indexed by string `impl IntoMockRow for BTreeMap<T, Value> where T: Into<String>`
    * Converts any string value into `ConnectOptions` - `impl From<T> for ConnectOptions where T: Into<String>`
    * Changed the parameter of method `ConnectOptions::new(T) where T: Into<String>` to takes any string SQL
    * Changed the parameter of method `Statement::from_string(DbBackend, T) where T: Into<String>` to takes any string SQL
    * Changed the parameter of method `Statement::from_sql_and_values(DbBackend, T, I) where I: IntoIterator<Item = Value>, T: Into<String>` to takes any string SQL
    * Changed the parameter of method `Transaction::from_sql_and_values(DbBackend, T, I) where I: IntoIterator<Item = Value>, T: Into<String>` to takes any string SQL
    * Changed the parameter of method `ConnectOptions::set_schema_search_path(T) where T: Into<String>` to takes any string
    * Changed the parameter of method `ColumnTrait::like()`, `ColumnTrait::not_like()`, `ColumnTrait::starts_with()`, `ColumnTrait::ends_with()` and `ColumnTrait::contains()` to takes any string
* Added `sea_query::{DynIden, RcOrArc, SeaRc}` to entity prelude https://github.com/SeaQL/sea-orm/pull/1661
* Added `expr`, `exprs` and `expr_as` methods to `QuerySelect` trait https://github.com/SeaQL/sea-orm/pull/1702
* Added `DatabaseConnection::ping` https://github.com/SeaQL/sea-orm/pull/1627
```rust
|db: DatabaseConnection| {
    assert!(db.ping().await.is_ok());
    db.clone().close().await;
    assert!(matches!(db.ping().await, Err(DbErr::ConnectionAcquire)));
}
```
* Added `TryInsert` that does not panic on empty inserts https://github.com/SeaQL/sea-orm/pull/1708
```rust
// now, you can do:
let res = Bakery::insert_many(std::iter::empty())
    .on_empty_do_nothing()
    .exec(db)
    .await;

assert!(matches!(res, Ok(TryInsertResult::Empty)));
```
* Insert on conflict do nothing to return Ok https://github.com/SeaQL/sea-orm/pull/1712
```rust
let on = OnConflict::column(Column::Id).do_nothing().to_owned();

// Existing behaviour
let res = Entity::insert_many([..]).on_conflict(on).exec(db).await;
assert!(matches!(res, Err(DbErr::RecordNotInserted)));

// New API; now you can:
let res =
Entity::insert_many([..]).on_conflict(on).do_nothing().exec(db).await;
assert!(matches!(res, Ok(TryInsertResult::Conflicted)));
```

### Bug Fixes

* Fixed `DeriveActiveEnum` throwing errors because `string_value` consists non-UAX#31 compliant characters https://github.com/SeaQL/sea-orm/pull/1374
```rust
#[derive(EnumIter, DeriveActiveEnum)]
#[sea_orm(rs_type = "String", db_type = "String(None)")]
pub enum StringValue {
    #[sea_orm(string_value = "")]
    Member1,
    #[sea_orm(string_value = "$$")]
    Member2,
}
// will now produce the following enum:
pub enum StringValueVariant {
    __Empty,
    _0x240x24,
}
```
* [sea-orm-cli] Fix Postgres enum arrays https://github.com/SeaQL/sea-orm/pull/1678
* [sea-orm-cli] The implementation of `Related<R>` with `via` and `to` methods will not be generated if there exists multiple paths via an intermediate table https://github.com/SeaQL/sea-orm/pull/1435
* [sea-orm-cli] fixed entity generation includes partitioned tables https://github.com/SeaQL/sea-orm/issues/1582, https://github.com/SeaQL/sea-schema/pull/105
* Fixed `ActiveEnum::db_type()` return type does not implement `ColumnTypeTrait` https://github.com/SeaQL/sea-orm/pull/1576
* Resolved `insert_many` failing if the models iterator is empty https://github.com/SeaQL/sea-orm/issues/873

### Breaking changes

* Supports for partial select of `Option<T>` model field. A `None` value will be filled when the select result does not contain the `Option<T>` field instead of throwing an error. https://github.com/SeaQL/sea-orm/pull/1513
* Replaced `sea-strum` dependency with upstream `strum` in `sea-orm` https://github.com/SeaQL/sea-orm/pull/1535
    * Added `derive` and `strum` features to `sea-orm-macros`

* Added a new variant `Many` to `Identity` https://github.com/SeaQL/sea-orm/pull/1508
* Enabled `hashable-value` feature in SeaQuery, thus `Value::Float(NaN) == Value::Float(NaN)` would be true https://github.com/SeaQL/sea-orm/pull/1728, https://github.com/SeaQL/sea-orm/pull/1743
* The `DeriveActiveEnum` derive macro no longer implement `std::fmt::Display`. You can use the new `DeriveDisplay` macro https://github.com/SeaQL/sea-orm/pull/1726
* `sea-query/derive` is no longer enabled by `sea-orm`, as such, `Iden` no longer works as a derive macro (it's still a trait). Instead, we are shipping a new macro `DeriveIden` https://github.com/SeaQL/sea-orm/pull/1740 https://github.com/SeaQL/sea-orm/pull/1755
```rust
// then:

#[derive(Iden)]
#[iden = "category"]
pub struct CategoryEnum;

#[derive(Iden)]
pub enum Tea {
    Table,
    #[iden = "EverydayTea"]
    EverydayTea,
}

// now:

#[derive(DeriveIden)]
#[sea_orm(iden = "category")]
pub struct CategoryEnum;

#[derive(DeriveIden)]
pub enum Tea {
    Table,
    #[sea_orm(iden = "EverydayTea")]
    EverydayTea,
}

-   fn try_get(res: &QueryResult, pre: &str, col: &str) -> Result<Self, TryGetError> {
+   fn try_get_by<I: sea_orm::ColIdx>(res: &QueryResult, idx: I) -> Result<Self, TryGetError> {
-       let value: YYY = res.try_get(pre, col).map_err(TryGetError::DbErr)?;

}
```
* The `ActiveModelBehavior` trait becomes async trait https://github.com/SeaQL/sea-orm/pull/1328.
If you overridden the default `ActiveModelBehavior` implementation:
```rust
#[async_trait::async_trait]
impl ActiveModelBehavior for ActiveModel {
    async fn before_save<C>(self, db: &C, insert: bool) -> Result<Self, DbErr>
    where
        C: ConnectionTrait,
    {
        // ...
    }

    // ...
}
```
* `DbErr::RecordNotFound("None of the database rows are affected")` is moved to a dedicated error variant `DbErr::RecordNotUpdated` https://github.com/SeaQL/sea-orm/pull/1425
```rust
let res = Update::one(cake::ActiveModel {
        name: Set("Cheese Cake".to_owned()),
        ..model.into_active_model()
    })
    .exec(&db)
    .await;

// then
assert_eq!(
    res,
    Err(DbErr::RecordNotFound(
        "None of the database rows are affected".to_owned()
    ))
);

// now
assert_eq!(res, Err(DbErr::RecordNotUpdated));
```
* `sea_orm::ColumnType` was replaced by `sea_query::ColumnType` https://github.com/SeaQL/sea-orm/pull/1395
    * Method `ColumnType::def` was moved to `ColumnTypeTrait`
    * `ColumnType::Binary` becomes a tuple variant which takes in additional option `sea_query::BlobSize`
    * `ColumnType::Custom` takes a `sea_query::DynIden` instead of `String` and thus a new method `custom` is added (note the lowercase)
```diff
// Compact Entity
#[derive(Clone, Debug, PartialEq, Eq, DeriveEntityModel)]
#[sea_orm(table_name = "fruit")]
pub struct Model {
-   #[sea_orm(column_type = r#"Custom("citext".to_owned())"#)]
+   #[sea_orm(column_type = r#"custom("citext")"#)]
    pub column: String,
}
```
```diff
// Expanded Entity
impl ColumnTrait for Column {
    type EntityName = Entity;

    fn def(&self) -> ColumnDef {
        match self {
-           Self::Column => ColumnType::Custom("citext".to_owned()).def(),
+           Self::Column => ColumnType::custom("citext").def(),
        }
    }
}
```

* #### Feature flag revamp
    We now adopt the [weak dependency](https://blog.rust-lang.org/2022/04/07/Rust-1.60.0.html#new-syntax-for-cargo-features) syntax in Cargo. That means the flags `["sqlx-json", "sqlx-chrono", "sqlx-decimal", "sqlx-uuid", "sqlx-time"]` are not needed and now removed. Instead, `with-time` will enable `sqlx?/time` only if `sqlx` is already enabled. As a consequence, now the features `with-json`, `with-chrono`, `with-rust_decimal`, `with-uuid`, `with-time` will not be enabled as a side-effect of enabling `sqlx`.

* Returning by @billy1624 in https://github.com/SeaQL/sea-orm/pull/292

### Breaking Changes
* Refactor `paginate()` & `count()` utilities into `PaginatorTrait`. You can use the paginator as usual but you might need to import `PaginatorTrait` manually when upgrading from the previous version.
    ```rust
    use futures::TryStreamExt;
    use sea_orm::{entity::*, query::*, tests_cfg::cake};

    let mut cake_stream = cake::Entity::find()
        .order_by_asc(cake::Column::Id)
        .paginate(db, 50)
        .into_stream();

    while let Some(cakes) = cake_stream.try_next().await? {
        // Do something on cakes: Vec<cake::Model>
    }
    ```
* The helper struct `Schema` converting `EntityTrait` into different `sea-query` statements now has to be initialized with `DbBackend`.
    ```rust
    use sea_orm::{tests_cfg::*, DbBackend, Schema};
    use sea_orm::sea_query::TableCreateStatement;

    // 0.3.x
    let _: TableCreateStatement = Schema::create_table_from_entity(cake::Entity);

    // 0.4.x
    let schema: Schema = Schema::new(DbBackend::MySql);
    let _: TableCreateStatement = schema.create_table_from_entity(cake::Entity);
    ```
* When performing insert or update operation on `ActiveModel` against PostgreSQL, `RETURNING` clause will be used to perform select in a single SQL statement.
    ```rust
    // For PostgreSQL
    cake::ActiveModel {
        name: Set("Apple Pie".to_owned()),
        ..Default::default()
    }
    .insert(&postgres_db)
    .await?;

    assert_eq!(
        postgres_db.into_transaction_log(),
        vec![Transaction::from_sql_and_values(
            DbBackend::Postgres,
            r#"INSERT INTO "cake" ("name") VALUES ($1) RETURNING "id", "name""#,
            vec!["Apple Pie".into()]
        )]);
    ```
    ```rust
    // For MySQL & SQLite
    cake::ActiveModel {
        name: Set("Apple Pie".to_owned()),
        ..Default::default()
    }
    .insert(&other_db)
    .await?;

    assert_eq!(
        other_db.into_transaction_log(),
        vec![
            Transaction::from_sql_and_values(
                DbBackend::MySql,
                r#"INSERT INTO `cake` (`name`) VALUES (?)"#,
                vec!["Apple Pie".into()]
            ),
            Transaction::from_sql_and_values(
                DbBackend::MySql,
                r#"SELECT `cake`.`id`, `cake`.`name` FROM `cake` WHERE `cake`.`id` = ? LIMIT ?"#,
                vec![15.into(), 1u64.into()]
            )]);
    ```
