• Upgrade sea-query-binder to 0.3 #1366
• Upgrade sea-schema to 0.11 #1366

House Keeping

• Fixed all clippy warnings as of 1.67.0 #1426
• Removed dependency where not needed #1213
• Disabled default features and enabled only the needed ones #1300
• Cleanup panic and unwrap #1231
• Cleanup the use of vec! macro #1367

Bug Fixes

• [sea-orm-cli] Propagate error on the spawned child processes #1402
  • Fixes sea-orm-cli errors exit with error code 0 #1342
• Fixes DeriveColumn (by qualifying IdenStatic::as_str) #1280
• Prevent returning connections to pool with a positive transaction depth #1283
• Postgres insert many will throw RecordNotInserted error if non of them are being inserted #1021
  • Fixes inserting active models by insert_many with on_conflict and do_nothing panics if no rows are inserted on Postgres #899
• Don't call last_insert_id if not needed #1403
  • Fixes hitting 'negative last_insert_rowid' panic with Sqlite #1357
• Noop when update without providing any values #1384
  • Fixes Syntax Error when saving active model that sets nothing #1376

Breaking changes

• [sea-orm-cli] Enable --universal-time by default #1420
• Added RecordNotInserted and RecordNotUpdated to DbErr
• Added ConnectionTrait::execute_unprepared method #1327
• As part of #1311, the required method of TryGetable changed:

// 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:

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 ActiveModelBehaviour trait becomes async trait #1328.
  If you overridden the default ActiveModelBehaviour implementation:

#[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 #1425

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 #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)

// 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,
}

// 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(),
        }
    }
}

Miscellaneous

• Fixed a small typo #1391
• axum example should use tokio runtime #1428
