def atomic(self):
return atomic(self.database)<EOL>
Similar to `peewee.Database.atomic()` method, but returns
        **asynchronous** context manager.

        Example::

            async with objects.atomic():
                await objects.create(
                    PageBlock, key='intro',
                    text="There are more things in heaven and earth, "
                         "Horatio, than are dreamt of in your philosophy.")
                await objects.create(
                    PageBlock, key='signature', text="William Shakespeare")
