Introduction

FastAPI-Query-Conditions is a dependency that parses a query string into conditions using operators enclosed in square brackets. For example, if you send a request to /orders?amount[gte]=1000&amount[lt]=2000, you can use the query string as parsed conditions like this:

{"gte":1000,"lt":2000}

Install

> pip install fastapi-query-conditions

Quick Start

from typing import Dict

from fastapi import Depends, FastAPI
from fastapi_query_conditions import query_conditions

app = FastAPI()

@app.get("/items")
def read_root(amount: Dict[str, int] = Depends(query_conditions(field='amount', factory=int))):
    print(amount)
    return amount

Then, if you send a request to /items?amount[gte]=1000&amount[lt]=2000, you can check the following results.

{'gte': 1000, 'lt': 2000}

Also, you can use various factory functions for your query parameter.

from typing import Dict

from fastapi import Depends, FastAPI
from fastapi_query_conditions import query_conditions
from datetime import datetime

app = FastAPI()

@app.get("/orders")
def read_root(time: Dict[str, int] = Depends(query_conditions(field='time', factory=datetime.fromisoformat))):
    print(time)
    return time

Then, if you send a request to /orders?time[gte]=2022-10-18T12:00&time[lt]=2022-10-18T12:30, you can check the following results.

{'gte': datetime.datetime(2022, 10, 18, 12, 0), 'lt': datetime.datetime(2022, 10, 18, 12, 30)}
