cannot find derive macro `Selectable` in this scope

when I added the Selectable in rust diesel diesel = { version = "1.4.8", features = ["postgres","64-column-tables","chrono","serde_json"] } code like this:

#[derive(Insertable,Queryable,QueryableByName,Debug,Serialize,Deserialize,Default,Clone,Selectable)]
#[table_name = "bill_record"]
pub struct BillRecord {
    pub id: i64,
    pub created_time: i64,
    pub updated_time: i64,
    pub deleted: i32,
    pub user_id: i64,
    pub bill_book_id: i64,
    pub remark: Option<String>,
    pub amount: i64,
    pub bill_book_contents_id: i64,
    pub account_id: i32,
}

the compiler shows error cannot find derive macro Selectable in this scope. I have tried to add the micro driver like this in main.rs:

#[macro_use]
extern crate diesel;
#[macro_use]
extern crate diesel_drivers;

could not fixed this error, I also read the diesel source code and found the Selectable come from diesel_drivers. why could not fixed this problem even add the drivers macro? what should I do to fix it? I also tried to add use diesel::*; in the model, still not work.

Solution

  • Please try rectifying the typo - it is "derives" instead of "drivers"

    #[macro_use]
extern crate diesel;
#[macro_use]
extern crate diesel_derives;
