Tardis macro creates index with "if_not_exists"

[gudaoxuri]

Example

Domain

#[derive(Clone, Debug, PartialEq, DeriveEntityModel, TardisCreateEntity, TardisEmptyBehavior, TardisEmptyRelation)]
#[sea_orm(table_name = "tt_table")]
pub struct Model {
    #[sea_orm(primary_key, auto_increment = false)]
    pub id: String,
    pub pk_column_name: String,
    pub parent_pk_column_name: Option<String>,
    pub columns: Json,
    pub layouts: Option<Json>,
    pub styles: Option<Json>,

    #[index]
    #[sea_orm(extra = "DEFAULT CURRENT_TIMESTAMP")]
    pub create_time: chrono::DateTime<Utc>,
    #[index]
    #[sea_orm(extra = "DEFAULT CURRENT_TIMESTAMP")]
    pub update_time: chrono::DateTime<Utc>,

    #[fill_ctx(owner)]
    pub owner: String,
}

Initializer

    let db_kind = TardisFuns::reldb_by_module_or_default("").backend();
    let mut tx = TardisFuns::reldb_by_module_or_default("").conn();
    let compatible_type = TardisFuns::reldb_by_module_or_default("").compatible_type();
    tx.begin().await?;
    tx.init(tt_table::ActiveModel::init(db_kind, Some("update_time"), compatible_type)).await?;
    tx.commit().await?;

Error

ERROR tardis::db::reldb_client: [Tardis.RelDBClient] DbErr: Execution Error: error returned from database: relation "idx-tt_table_18uz" already exists

Macro code needs to add if_not_exists like this: Index::create().if_not_exists()
