custom_derive! + HasMany! not working for me

[bahlo]

I have a setup similar to your getting started guide and want to add the HasMany! macro with custom_derive.

Crate list in main.rs:

#![feature(custom_derive, custom_attribute, plugin)]
#![plugin(diesel_codegen, dotenv_macros)]

#[macro_use] extern crate diesel;
extern crate dotenv;
#[macro_use] extern crate custom_derive;

My user model:

custom_derive! {
    #[derive(Identifiable, HasMany(items, foreign_key = user_id))]
    #[table_name(users)]
    pub struct User {
        pub id: i32,
        // Other fields
    }
}

Cargo.toml excerpt

diesel = "0.6.2"
diesel_codegen = { version = "0.6.2", default-features = false, features = ["nightly", "postgres"] }
dotenv = "0.8.0"
dotenv_macros = "0.8.0"
custom_derive = "0.1.5"

When I run the code, I get the following output:

   Compiling my-app v0.1.0 (file:///Users/arne/Developer/my-app)
<custom_derive macros>:114:32: 114:33 error: macro undefined: 'Identifiable!'
<custom_derive macros>:114 $ ( $ user_drvs ) * $ new_user (  ) , ) } } ; (
                                                          ^

                                                          ^
error: aborting due to 2 previous errors
error: Could not compile `my-app`.

To learn more, run the command again with --verbose.

I'm thankful for any help 😊

Thanks for the detailed report!

HasMany! is not available in version 0.6.2, as it was introduced just 2 days ago in #386. The docs are rendered for the master branch. While there should be a new release 0.7 soon, you can track master in the meantime.

@killercup: Thanks for your help, didn't think of that. 🙈
