nevesdb 0.1.4

A simple to use database abstraction layer

NevesDB

NevesDB is a lightweight, easy-to-use asynchronous database ORM for Python. It simplifies database interactions by providing an intuitive interface for defining models, adding data, and retrieving records.

Features

• Asynchronous support
• Simple model definition
• Easy database initialization
• Automatic table creation
• Built-in CRUD operations

Installation

Ensure you have Python installed. Then, install NevesDB via pip:

pip install nevesdb  # Replace with actual package name if different

Usage

1. Initialize the Database

Create an instance of NevesDB and connect to your database:

from nevesdb import NevesDB

# Initialize the database (MySQL example)
db = NevesDB(db_type="mysql", db_user="root", db_password="password", db_name="test_db", db_url="localhost:3306")

2. Define a Model

Models define the structure of your database tables:

from nevesdb import Model


class User(Model):
    id: int = 1
    name: str = "John Doe"
    password: str = "password"

3. Register Models

Register the model to create the corresponding table in the database:

db.register_models([User])

4. Perform CRUD Operations

Add a User

import asyncio

async def add_user(user: User):
    await db.add(user)

user1 = User(id=1, name="Alice")
asyncio.run(add_user(user1))

Retrieve a User

async def get_user(user_id: int):
    return await db.get(User, {"id": user_id})

users = asyncio.run(get_user(1))
print(users)  # [{'id': 1, 'name': 'Alice', 'password': 'password'}]

Running the Example

To run the full example:

async def main():
    await add_user(user1)
    users = await get_user(1)
    print(users)

asyncio.run(main())
