There are a few differences:

* `table=True` tells SQLModel that this is a *table model*, it should represent a **table** in the SQL database, it's not just a *data model* (as would be any other regular Pydantic class).

* `Field(primary_key=True)` tells SQLModel that the `id` is the **primary key** in the SQL database (you can learn more about SQL primary keys in the SQLModel docs).

If you see a warning message like `gpg: WARNING: This key is not certified with a trusted signature!`, you can locally sign the Gradle key after importing it.
This tells your GPG installation that you trust this key and will prevent the warning from appearing again.

To do this, run the following command:

```bash
gpg --sign-key 1BD97A6A154E7810EE0BC832E2F38302C8075E3D
```
