# Database Migrations
|
||
|
|
|
||
|
|
This directory contains all the database migrations for the web app.
|
||
|
|
Migrations are done using the [`peewee-migrate`](https://github.com/klen/peewee_migrate) library.
|
||
|
|
|
||
|
|
Migrations are automatically ran at app startup.
|
||
|
|
|
||
|
|
## Creating a migration
|
||
|
|
|
||
|
|
Have you made a change to the schema of an existing model?
|
||
|
|
You will need to create a migration file to ensure that existing databases are updated for backwards compatibility.
|
||
|
|
|
||
|
|
1. Have a database file (`webui.db`) that has the old schema prior to any of your changes.
|
||
|
|
2. Make your changes to the models.
|
||
|
|
3. From the `backend` directory, run the following command:
|
||
|
|
```bash
|
||
|
|
pw_migrate create --auto --auto-source apps.web.models --database sqlite:///${SQLITE_DB} --directory apps/web/internal/migrations ${MIGRATION_NAME}
|
||
|
|
```
|
||
|
|
- `$SQLITE_DB` should be the path to the database file.
|
||
|
|
- `$MIGRATION_NAME` should be a descriptive name for the migration.
|
||
|
|
4. The migration file will be created in the `apps/web/internal/migrations` directory.
