I tried to run the app on my machine, but it did not work. Opening an issue here to (1) ask for tips for how to proceed and (2) document progress.

What I did

nix-shell
cargo run

Output

All the logs are warnings, so those can be ignored for the purposes of running the app. The core here is:

thread 'main' panicked at src/lib.rs:29:10:
Failed to create pool: Error(Some("Can't connect to server on '127.0.0.1' (36)"))

This refers to src/lib.rs line 29, which handles database connections. Can you verify mysql is running when you do cargo run? It looks like I only added the mysql client to nix, and it currently assumes it is running in the system beforehand. 😊 If you're on macOS it probably needs something like brew install mysql and the instructions it provides to get up and running.

Thanks for the tip!

I installed mysql and started the service. And now I'm getting an error that the database called "diesel_dev" is not found.

thread 'main' panicked at src/lib.rs:29:10:
Failed to create pool: Error(Some("Unknown database 'diesel_dev'"))
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

Perhaps a step to initialize the database is needed?

Ah yes - diesel migration run I believe. 👍 Does that do the trick?

If not, diesel database reset may also work.
