storyteller-web

This is our main user account monolith that we'll also bake other pieces into.

Local development

Setup

Install diesel,

sudo apt-get install libmysqlclient-dev
cargo install diesel_cli --no-default-features --features mysql

If MySql in local dev can't be connected to, reset the accounts:

https://linuxconfig.org/how-to-reset-root-mysql-mariadb-password-on-ubuntu-20-04-focal-fossa-linux

Database migrations

To reset the entire database (drop, migrate), run:

diesel database reset

To migrate at the current step and beyond:

diesel migration run

To undo migrations at the current step:

diesel migration redo

To save sqlx database state to cache file (necessary for builds):

SQLX_OFFLINE=true cargo sqlx prepare

Now that we have multiple binaries, it's required to include all the queries in the main binary so we can generate the cached queries as a single target. That's then executed with:

SQLX_OFFLINE=true cargo sqlx prepare -- --bin storyteller-web

Production

Database migrations

1. Set DATABASE_URL in .env
2. Run diesel migration run

Actix notes

json request

async fn handler(request: web::Json<Mytype>) -> impl Responder { "whatever" }

form-multipart request

async fn handler(request: web::Form<Mytype>) -> impl Responder { "whatever" }

route parameters

#[get("/{name}")]
async fn hello(name: web::Path<String>) -> impl Responder { format!("Hi {}", name) }

TODO

• Make all "token" types correct
• Use correct collation for all tables
• Install indexes on all foreign keys
• Make sure unique indexes are correct

Notes / TODOs:

• Examples for good Actix+Sqlx Tests: https://stackoverflow.com/questions/65370752/how-do-i-create-an-actix-web-server-that-accepts-both-sqlx-database-pools-and-tr

• Actix/sqlx runtime compat: https://github.com/launchbadge/sqlx/issues/1117#issuecomment-801237734

Docker builds

The repository needs to be given read access to the base docker image:

Local Nginx Proxy

Set up a local nginx to proxy to the frontend and backend so cookie issues aren't annoying

Edit, /etc/nginx/sites-enabled/storyteller

server {
    listen 80;
    server_name api.jungle.horse;
    location / {
        proxy_set_header Host $host;
        proxy_pass http://127.0.0.1:12345;
        proxy_redirect off;
    }
}
server {
    listen 80;
    server_name jungle.horse;
    location / {
        proxy_set_header Host $host;
        proxy_pass http://127.0.0.1:7000;
        proxy_redirect off;
    }
}

Fixing dev MySql on Ubuntu 20.04

For some reason, the MySql default install on 20.04 gave me a bunch of trouble.

In retrospect, I think this is because 'root@localhost' requires sudo to access, but if this gives any trouble in the future, here's how I got around it (two full hours of distraction!)

sudo apt-get install mysql-server

# But for some reason the default password doesn't work and diesel/sqlx can't connect?

# Kill everything

sudo apt purge mysql-server mysql-client mysql-common
sudo apt autoremove
sudo mv -iv /var/lib/mysql /var/tmp/mysql-backup
sudo rm -rf /var/lib/mysql*

sudo /usr/bin/mysql_secure_installation

# still no work...

sudo systemctl stop mysql.service

# ugh, it wasn't chowned or created (both states observed in different installs)…
sudo mkdir -p /var/run/mysqld
sudo chown mysql:mysql /var/run/mysqld

sudo mysqld_safe --skip-grant-tables --skip-networking &

mysql -u root

flush privileges;
USE mysql;
ALTER USER 'root'@'localhost' IDENTIFIED BY 'root';

sudo killall -u mysql
sudo systemctl restart mysql.service

# now it works
sudo mysql -u root -p

# but now I have to use "sudo" !?!?

CREATE USER 'storyteller'@'localhost' IDENTIFIED BY 'password';
GRANT ALL PRIVILEGES ON storyteller.* TO 'storyteller'@'localhost';
