# Database Migration
|
|
|
|
### DB migration:
|
|
|
|
Alembic is used for database migrations.
|
|
|
|
To change any database model, follow these steps.
|
|
|
|
- Make sure that squeaknode on your local machine is running with the most up-to-date database migration.
|
|
- Make a note of the path to the ".db" sqlite database file. (Usually `~/.sqk/data/testnet/data.db` by default). If this is an initial migration, then create an empty file at this location.
|
|
- Make the changes to database models in `squeaknode/db/models.py`
|
|
- Update the `alembic.ini` file to point to the sqlite file from before:
|
|
```
|
|
sqlalchemy.url = sqlite://///home/<USER>/.sqk/data/testnet/data.db
|
|
```
|
|
- Run the command to generate a new alembic migration:
|
|
```
|
|
python3 -m venv venv
|
|
source venv/bin/activate
|
|
pip install -e .
|
|
alembic -c squeaknode/db/alembic.ini revision --autogenerate -m "<YOUR_MESSAGE>"
|
|
```
|
|
- To generate a new initial version revision, follow the same steps as above, but the `/home/<USER>/.sqk/data/testnet/data.db` file should be an empty file.
