sea-orm Fails to Apply Default Value for 'created_at' Field in SQLite about sea-orm

[Ethan1225]

the error comes from create_table_from_entity:

    let db = Database::connect("sqlite::memory:").await?; 
    let schema = Schema::new(DbBackend::Sqlite); 
    let stmt: TableCreateStatement = schema.create_table_from_entity(meetings::Entity);

the ddl created from create_table_from_entity:

   CREATE TABLE "meetings" ( "id" integer NOT NULL PRIMARY KEY AUTOINCREMENT, "name" text NOT NULL, "meeting_guid" text NOT NULL, "meeting_datetime" text, "created_at" text NOT NULL, "updated_at" text NOT NULL )

Marking a column as Option<T> only means it is nullable, it does not specify that it should have a default value.

You can add an attribute:

• Supporting default_expr in DeriveEntityModel #1474

#[derive(DeriveEntityModel)]
#[sea_orm(table_name = "hello")]
pub struct Model {
    #[sea_orm(default_expr = "Expr::current_timestamp()")]
    pub timestamp: DateTimeUtc,
}
