piccolo 1.31.0

A fast, user friendly ORM and query builder which supports asyncio.

Piccolo is 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
)

# Join:
await Band.select(
    Band.name,
    Band.manager.name
)

# Delete:
await Band.delete().where(
    Band.popularity < 1000
)

# Update:
await Band.update({Band.popularity: 10000}).where(
    Band.name == 'Pythonistas'
)

Or like a typical ORM:

# To create a new object:
b = Band(name='C-Sharps', popularity=100)
await b.save()

# To fetch an object from the database, and update it:
b = await Band.objects().get(Band.name == 'Pythonistas')
b.popularity = 10000
await b.save()

# To delete:
await b.remove()

Piccolo Admin

Piccolo Admin is a powerful admin interface / content management system for Python, built on top of Piccolo.

It was created at a design agency to serve the needs of customers who demand a high quality, beautiful admin interface for their websites. It's a modern alternative to tools like Wordpress and Django Admin.

Some of it's standout features:

• Powerful data filtering
• Builtin security
• Multi-factor Authentication
• Media support, both locally and in S3 compatible services
• Dark mode support
• CSV exports
• Easily create custom forms
• Works on mobile and desktop
• Use standalone, or integrate with several supported ASGI frameworks
• Multilingual out of box
• Bulk actions, like updating and deleting data
• Flexible UI - only show the columns you want your users to see
