Async support for a range of databases
Project description
Muffin-Databases – Async support for a range of databases for Muffin Framework
Requirements
python >= 3.7
Installation
Muffin-Databases should be installed using pip:
$ pip install muffin-databases
Optionally you can install the required database drivers with:
$ pip install muffin-databases[sqlite] $ pip install muffin-databases[postgres] $ pip install muffin-databases[mysql]
Driver support is provided using one of asyncpg, aiomysql, or aiosqlite.
Usage
Setup the plugin and connect it into your app:
from muffin import Application
from muffin_databases import Plugin as DB
# Create Muffin Application
app = Application('example')
# Initialize the plugin
# As alternative: db = DB(app, **options)
db = DB(url='sqlite:///db.sqlite')
db.setup(app)That’s it now you are able to use the plugin inside your views:
@app.route('/items', methods=['GET'])
async def get_items(request):
"""Return a JSON with items from database."""
rows = await db.fetch_all('SELECT * from items')
return [dict(row.items()) for row in rows]
@app.route('/items', methods=['POST'])
async def insert_item(request):
"""Store an item into database."""
data = await request.data() # parse formdata/json from the request
await db.execute_many('INSERT INTO items (name, value) VALUES (:name, :value)', values=data)
return 'OK'The Muffin-Databases plugin is based on databases. See the databases’s docs for further references.
