## 0.12.0 - Pending

### New Features

* 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 without throwing an error. https://github.com/SeaQL/sea-orm/pull/1513
```rs
customer::ActiveModel {
    name: Set("Alice".to_owned()),
    notes: Set(Some("Want to communicate with Bob".to_owned())),
    ..Default::default()
}
.save(db)
.await?;

// The `notes` field was intentionally leaved out
let customer = Customer::find()
    .select_only()
    .column(customer::Column::Id)
    .column(customer::Column::Name)
    .one(db)
    .await
    .unwrap();

// The select result does not contain `notes` field.
// Since it's of type `Option<String>`, it'll be `None` and no error will be thrown.
assert_eq!(customers.notes, None);
```
* Added `sea_orm_macros::EnumIter` to implement `strum::IntoEnumIterator` trait for the derived enum (source code adapted from https://github.com/Peternator7/strum)
* [sea-orm-cli] the `migrate init` command will create a `.gitignore` file when the migration folder reside in a Git repository https://github.com/SeaQL/sea-orm/pull/1334

### Enhancements

* Added `Migration::name()` and `Migration::status()` getters for the name and status of `sea_orm_migration::Migration` https://github.com/SeaQL/sea-orm/pull/1519
```rs
let migrations = Migrator::get_pending_migrations(db).await?;
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);
```

### Upgrades

* Upgrade `heck` dependency in `sea-orm-macros` and `sea-orm-codegen` to 0.4 https://github.com/SeaQL/sea-orm/pull/1520, https://github.com/SeaQL/sea-orm/pull/1544
* Upgrade `strum` to 0.24
* Upgrade `sea-query` to `0.29` https://github.com/SeaQL/sea-orm/pull/1562
* Upgrade `sea-query-binder` to `0.4` https://github.com/SeaQL/sea-orm/pull/1562
* Upgrade `sea-schema` to `0.12` https://github.com/SeaQL/sea-orm/pull/1562

### Bug Fixes

* Fixed `DeriveActiveEnum` throwing errors because `string_value` consists non-UAX#31 compliant characters https://github.com/SeaQL/sea-orm/pull/1374

For example,
```rust
#[derive(Clone, Debug, PartialEq, EnumIter, DeriveActiveEnum)]
#[sea_orm(rs_type = "String", db_type = "String(None)")]
pub enum StringValue {
    #[sea_orm(string_value = "")]
    Member1,
    #[sea_orm(string_value = "$")]
    Member2,
    #[sea_orm(string_value = "$$")]
    Member3,
    #[sea_orm(string_value = "AB")]
    Member4,
    #[sea_orm(string_value = "A_B")]
    Member5,
    #[sea_orm(string_value = "A$B")]
    Member6,
    #[sea_orm(string_value = "0 123")]
    Member7,
}
```
will now produce the following Variant Enum:
```rust
pub enum StringValueVariant {
    __Empty,
    _0x24,
    _0x240x24,
    Ab,
    A0x5Fb,
    A0x24B,
    _0x300x20123,
}
```

### 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 without throwing an error. https://github.com/SeaQL/sea-orm/pull/1513
* Added `derive` and `strum` features to `sea-orm-macros`
* Replaced `sea-strum` dependency with `strum` in `sea-orm`
* Re-exported `sea_orm_macros::EnumIter` instead of `strum::EnumIter` on the root of `sea-orm`
* The Variant Enum generated by `DeriveActiveEnum` will properly escape non-UAX#31 compliant characters

## 0.11.2 - 2023-03-25

### Bug Fixes

* Fixes `DeriveActiveEnum` (by qualifying `ColumnTypeTrait::def`) https://github.com/SeaQL/sea-orm/issues/1478
* The CLI command `sea-orm-cli generate entity -u '<DB-URL>'` will now generate the following code for each `Binary` or `VarBinary` columns in compact format https://github.com/SeaQL/sea-orm/pull/1529
```rs
#[derive(Clone, Debug, PartialEq, DeriveEntityModel, Eq)]
#[sea_orm(table_name = "binary")]
pub struct Model {
    #[sea_orm(primary_key)]
    pub id: i32,
    #[sea_orm(column_type = "Binary(BlobSize::Blob(None))")]
    pub binary: Vec<u8>,
    #[sea_orm(column_type = "Binary(BlobSize::Blob(Some(10)))")]
    pub binary_10: Vec<u8>,
    #[sea_orm(column_type = "Binary(BlobSize::Tiny)")]
    pub binary_tiny: Vec<u8>,
    #[sea_orm(column_type = "Binary(BlobSize::Medium)")]
    pub binary_medium: Vec<u8>,
    #[sea_orm(column_type = "Binary(BlobSize::Long)")]
    pub binary_long: Vec<u8>,
    #[sea_orm(column_type = "VarBinary(10)")]
    pub var_binary: Vec<u8>,
}
```
* The CLI command `sea-orm-cli generate entity -u '<DB-URL>' --expanded-format` will now generate the following code for each `Binary` or `VarBinary` columns in expanded format https://github.com/SeaQL/sea-orm/pull/1529
```rs
impl ColumnTrait for Column {
    type EntityName = Entity;
    fn def(&self) -> ColumnDef {
        match self {
            Self::Id => ColumnType::Integer.def(),
            Self::Binary => ColumnType::Binary(sea_orm::sea_query::BlobSize::Blob(None)).def(),
            Self::Binary10 => {
                ColumnType::Binary(sea_orm::sea_query::BlobSize::Blob(Some(10u32))).def()
            }
            Self::BinaryTiny => ColumnType::Binary(sea_orm::sea_query::BlobSize::Tiny).def(),
            Self::BinaryMedium => ColumnType::Binary(sea_orm::sea_query::BlobSize::Medium).def(),
            Self::BinaryLong => ColumnType::Binary(sea_orm::sea_query::BlobSize::Long).def(),
            Self::VarBinary => ColumnType::VarBinary(10u32).def(),
        }
    }
}

    * Fixes Syntax Error when saving active model that sets nothing https://github.com/SeaQL/sea-orm/pull/1376

### Breaking Changes

* [sea-orm-cli] Enable --universal-time by default https://github.com/SeaQL/sea-orm/pull/1420
* Added `RecordNotInserted` and `RecordNotUpdated` to `DbErr` 
* Added `ConnectionTrait::execute_unprepared` method https://github.com/SeaQL/sea-orm/pull/1327
* As part of https://github.com/SeaQL/sea-orm/pull/1311, the required method of `TryGetable` changed:
```rust
// then
fn try_get(res: &QueryResult, pre: &str, col: &str) -> Result<Self, TryGetError>;
// now; ColIdx can be `&str` or `usize`
fn try_get_by<I: ColIdx>(res: &QueryResult, index: I) -> Result<Self, TryGetError>;
```
So if you implemented it yourself:
```patch
impl TryGetable for XXX {
-   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)?;
+       let value: YYY = res.try_get_by(idx).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(),
        }
    }
}
```

#[derive(Iden)]
enum TeaEnum {
    #[iden = "tea"]
    Enum,
    #[iden = "EverydayTea"]
    EverydayTea,
    #[iden = "BreakfastTea"]
    BreakfastTea,
}

// then
ColumnDef::new(active_enum_child::Column::Tea)
    .enumeration("tea", vec!["EverydayTea", "BreakfastTea"])

// now
ColumnDef::new(active_enum_child::Column::Tea)
    .enumeration(TeaEnum::Enum, [TeaEnum::EverydayTea, TeaEnum::BreakfastTea])
```

* A new method `array_type` was added to `ValueType`:
```rust
impl sea_orm::sea_query::ValueType for MyType {
    fn array_type() -> sea_orm::sea_query::ArrayType {
        sea_orm::sea_query::ArrayType::TypeName
    }
    ...
}
```

* `ActiveEnum::name()` changed return type to `DynIden`:
```rust
#[derive(Debug, Iden)]
#[iden = "category"]
pub struct CategoryEnum;

impl ActiveEnum for Category {
    // then
    fn name() -> String {
        "category".to_owned()
    }

    // now
    fn name() -> DynIden {
        SeaRc::new(CategoryEnum)
    }
    ...
}
```

### Breaking Changes

* `SelectTwoMany::one()` has been dropped https://github.com/SeaQL/sea-orm/pull/813, you can get `(Entity, Vec<RelatedEntity>)` by first querying a single model from Entity, then use [`ModelTrait::find_related`] on the model.
* #### 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`.

### 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};

    .exec(&db)
    .await,
    Err(DbErr::RecordNotFound(
        "None of the database rows are affected".to_owned()
    ))
);

// update many remains the same
assert_eq!(
    Update::many(cake::Entity)
        .col_expr(cake::Column::Name, Expr::value("Cheese Cake".to_owned()))
        .filter(cake::Column::Id.eq(2))
