A pure python library inspired by the NuGet library dapper.
pydapper is built on top of the dbapi 2.0 spec to provide more convenient methods for working with databases in python.
See the documentation for more details.
It is recommended to only install the database apis you need for your use case. Example below is for psycopg2!
pip install pydapper[psycopg2]poetry add pydapper -E psycopg2from psycopg2 import connect
@dataclass
class Task:
id: int
description: str
due_date: datetime.date
with connect("postgresql://pydapper:pydapper@localhost/pydapper") as conn:
with conn.cursor() as cursor:
cursor.execute("select id, description, due_date from task")
headers = [i[0] for i in cursor.description]
data = cursor.fetchall()
list_data = [Task(**dict(zip(headers, row))) for row in data]from dataclasses import dataclass
import datetime
import pydapper
@dataclass
class Task:
id: int
description: str
due_date: datetime.date
with pydapper.connect("postgresql psycopg2://pydapper:pydapper@locahost/pydapper") as commands:
tasks = commands.query("select id, description, due_date from task;", model=Task)(This script is complete, it should run "as is")
