  1. Whoa. Can’t believe I’ve been doing this the wrong way. Thank you for this guide – it’s timely indeed.

  2. Please stop recommending Rocket. It should be considered depreciated. It is no longer actively maintained. I would recommend using something like Axum since it is very well maintained.

    1. Hi Elliot,

      We already have an article about using Actix-web framework here: https://blog.logrocket.com/building-rest-api-rust-rhai-actix-web/. However, based on high requests from developers, this one had to be addressed.

      Refer to this report on Stackshare to confirm how Rocket is more used before now: https://stackshare.io/stackups/actix-vs-rocket#:~:text=Rocket%20and%20Actix%20can%20be,stars%20and%20216%20GitHub%20forks.

      But your point and recommendations are very valid, we only hope you understand ours too.

  3. Hey! I am a beginner with the rust programming language and I find this tutorial great. I followed all the steps, but after I run the “cargo run” command, I get the following error:

    error with configuration: unrecognized database url: “test_data.db”
    –> src/database.rs:20:14
    |
    20 | let id = sqlx::query_as!(
    | ______________^
    21 | | Profile,
    22 | | r#”
    23 | | INSERT INTO profiles (name, humidity_min, humidity_max, light) VALUES (?, ?, ?, ?);
    … |
    28 | | light
    29 | | )
    | |_____^
    |
    = note: this error originates in the macro `$crate::sqlx_macros::expand_query` which comes from the expansion of the macro `sqlx::query_as` (in Nightly builds, run with -Z macro-backtrace for more info)

    1. sorry my personal changed were applied, it is rather this error:

      error: error with configuration: unrecognized database url: “data.db”
      –> src/database.rs:18:14
      |
      18 | let id = sqlx::query_as!(
      | ______________^
      19 | | Task,
      20 | | r#”
      21 | | INSERT INTO tasks (name, description) VALUES (?, ?);
      … |
      24 | | description
      25 | | )
      | |_____^

      1. change your .env file to
        “`
        DATABASE_URL=sqlite://data.db
        “`
        and the start of your main function to
        “`
        let mut config = sqlx::sqlite::SqliteConnectOptions::new();
        config = config.filename(“data.db”);

        let pool = SqlitePool::connect_with(config)
        .await
        .expect(“Couldn’t connect to sqlite database”);
        “`
        and ofc you can modify the config as you want

        1. Hi — Thank you for that ‘obvious’ tip, that I didn’t see. I used the `env` file to set my DB to use a relative path as: “sqlite://../data/data.db”. It just works. Gotta love Rust (sometimes).
