### DB migration:
|
|
|
|
Alembic is used for database migrations.
|
|
|
|
To change any database model, follow these steps.
|
|
|
|
- Make sure that you have an up-to-date squeaknode with a sqlite database.
|
|
- Make a note of the path to the ".db" sqlite database file. (Usually `~/.sqk/data/testnet/data.db` by default)
|
|
- 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:
|
|
```
|
|
$ virtuelenv venv
|
|
$ pip install -r requirements.txt
|
|
$ pip install -e .
|
|
$ alembic revision --autogenerate -m "<YOUR_MESSAGE>"
|
|
```
