fastapi-query-tools 1.0.0

A package to simplify filtering and sorting in FastAPI

Introduction

fastapi-query-tools is a Python library designed to simplify filtering and sorting in FastAPI applications. It provides a set of utility functions and data models to help you filter, sort, and order your data to be returned to your clients.

fastapi-query-tools is built on top of the popular fastapi library. It is currently designed to work with SQLAlchemy, but support for other databases may be added in the future. It is compatible with Python 3.10 and higher.

Features:

• Simplifies filtering and sorting in FastAPI applications.
• Supports a query, a sort by, and an order by system.
• Works with SQLAlchemy.
• Compatible with Python 3.10 and higher.

Installation

pip install fastapi-query-tools

Quickstart

All you need to do is to add the Filter dependency to the endpoint params and call filter_and_sort function on data you want to filter and/or sort.

from fastapi import FastAPI, Depends
from sqlalchemy import select

# import all you need from fastapi-query-tools
from fastapi_query_tools import Filter, filter_and_sort

app = FastAPI()  # create FastAPI app


@app.get('/items')
async def get_items(*, db: Session = Depends(get_db), filter: Filter) -> List[ItemOut]:
    stmt = select(Item)
    query = filter_and_sort(stmt, filter)
    return db.execute(query).scalars().all() # filter and sort data and return

Example Request

curl -X 'GET' \
  'http://localhost:8000/api/items?q=item&sort_by=name&order=desc' \
  -H 'accept: application/json' \

Where q is a query, sort_by is a field (column) to sort by, and order (asc, desc) is an order of sorting.
