How to use parquet alongside with auto_increment = false?

[sagoez]

#[sea_orm::model]
#[derive(Clone, Debug, PartialEq, DeriveEntityModel, Eq, Serialize, Deserialize)]
#[sea_orm(table_name = "my_table", arrow_schema)]
pub struct Model {
    #[sea_orm(primary_key)]
    #[sea_orm(auto_increment = false)]
    pub id:            Uuid,
..
}

I get a syntax error: expected ','. Not sure what can be done or if I can just remove the auto_increment since I guess my db should understand that it is not autoincrement since is UUID

thank for reporting, let me check. fixed in 6b3edde

Looks like this was a macro parsing bug around combining arrow_schema with auto_increment = false.

Since it was fixed in 6b3edde, I’d try updating SeaORM / sea-orm-macros to a version that includes that commit.

I would not remove auto_increment = false for a UUID primary key. For UUID ids it’s still better to keep it explicit:

#[sea_orm(primary_key, auto_increment = false)]
pub id: Uuid,

So the expected fix is probably:

• update to the latest SeaORM version / git revision
• keep auto_increment = false
• rerun the derive

If it still fails on latest, then it’s worth opening a small repro with arrow_schema + Uuid primary key.
