Oxidetalis database migrations

This crate contains the database migrations for the Oxidetalis homeserver, using SeaORM.

How to run the migrations

The migrations are run when the server starts. The server will check if the database is up-to-date and run the migrations if needed. So, you don't need to run the migrations manually.

How to create a new migration

The migrations will saved in the database, so SeaORM will track the migrations, and you don't need to worry about the migration files, just write the migration and SeaORM will take care of the rest.

To create a new migration, you need to create a new migration file in the src directory. You can name the file anything you want, for example, create_users_table.rs. The file should contain the migration code, you can take this as a template:

use sea_orm_migration::prelude::*;

#[derive(DeriveMigrationName)]
pub struct Migration;

#[async_trait::async_trait]
impl MigrationTrait for Migration {
    async fn up(&self, manager: &SchemaManager) -> Result<(), DbErr> {
        // Here you can write the migration code, the `manager` can do anything you want.
        
        // When the homeserver starts, it will run the `up` function for each migration that is not run yet.
    }
}

#[derive(DeriveIden)]
enum TableName {
    Table, // Required for the table name
    Id, // Required for the primary key
    // Add more columns here
d}

[!NOTE] Don't write the down function, I prefer to do each migration in a separate migration file, so you don't need to write the down function. If you want to delete a table later, you can create a new migration file that deletes the table.

After you write the migration code, you need to add the migration to the src/lib.rs file.
