# 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:
|
|
```rust
|
|
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.
