This ORM doesn't seem to work anymore.
I want to apologize. This worked like a charm. My database tool however is completely fucked. Sorry for the inconvenience.
I'm using Python 3.9.6, and the example provided in the readme is broken:

```
import datetime

import peewee

db = peewee.SqliteDatabase('my_database.db')


class BaseModel(peewee.Model):
    class Meta:
        database = db


class User(BaseModel):
    username = peewee.CharField(unique=True)


class Tweet(BaseModel):
    user = peewee.ForeignKeyField(User, backref='tweets')
    message = peewee.TextField()
    created_date = peewee.DateTimeField(default=datetime.datetime.now)
    is_published = peewee.BooleanField(default=True)


db.connect()
db.create_tables([User, Tweet])
charlie = User.create(username='charlie')
huey = User(username='huey')
huey.save()

# No need to set `is_published` or `created_date` since they
# will just use the default values we specified.
Tweet.create(user=charlie, message='My first tweet')
```

Accourding to the readme this code should be working? I would expect a database with 2 tables and some data in it. The db is created but empty.
