Piccolo
A fast, user friendly ORM and query builder which supports asyncio. Read the docs.
Features
Some of it’s stand out features are:
- Support for sync and async.
- A builtin playground, which makes learning a breeze.
- Tab completion support - works great with iPython and VSCode.
- Batteries included - a User model, authentication, migrations, an admin GUI, and more.
- Modern Python - fully type annotated.
- Make your codebase modular and scalable with Piccolo apps (similar to Django apps).
Syntax
The syntax is clean and expressive.
You can use it as a query builder:
# Select:
await Band.select(
Band.name
).where(
Band.popularity > 100
).run()
# Join:
await Band.select(
Band.name,
Band.manager.name
).run()
# Delete:
await Band.delete().where(
Band.popularity < 1000
).run()
# Update:
await Band.update({Band.popularity: 10000}).where(
Band.name == 'Pythonistas'
).run()
Or like a typical ORM:
# To create a new object:
b = Band(name='C-Sharps', popularity=100)
await b.save().run()
# To fetch an object from the database, and update it:
b = await Band.objects().get(Band.name == 'Pythonistas').run()
b.popularity = 10000
await b.save().run()
# To delete:
await b.remove().run()
