ORM

IN PROGRESS

Seriously, it's in progress - we don't even have foreign key support in here yet. But it's a nice start.

Note: Use ipython to try this from the console, since it supports await.

import databases
import orm
import sqlalchemy

database = databases.Database("sqlite:///db.sqlite")
metadata = sqlalchemy.MetaData()


class Note(orm.Model):
    __tablename__ = "notes"
    __database__ = database
    __metadata__ = metadata

    id = orm.Integer(primary_key=True)
    text = orm.String(max_length=100)
    completed = orm.Boolean(default=False)

# Create the database
engine = sqlalchemy.create_engine(str(database.url))
metadata.create_all(engine)

# .create()
await Note.objects.create(text="Buy the groceries.", completed=False)
await Note.objects.create(text="Call Mum.", completed=True)
await Note.objects.create(text="Send invoices.", completed=True)

# .all()
notes = await Note.objects.all()

# .filter()
notes = await Note.objects.filter(completed=True).all()

# exact, iexact, contains, icontains, lt, lte, gt, gte, in
notes = await Note.objects.filter(text__icontains="mum").all()

# .get()
note = await Note.objects.get(id=1)

# .update()
await note.update(completed=True)

# .delete()
await note.delete()
