fastapi-filters
Project description
Introduction
fastapi-filters
is a library that provides filtering/sorting feature for FastAPI
applications.
Installation
pip install fastapi-filters
Quickstart
To create filters you need either define them manually using create_filters
function or automatically generate them
based on model using create_filters_from_model
function.
from typing import List
from fastapi import FastAPI, Depends
from pydantic import BaseModel, Field
# import all you need from fastapi-filters
from fastapi_filters import create_filters, create_filters_from_model, FilterValues
app = FastAPI() # create FastAPI app
class UserOut(BaseModel): # define your model
name: str = Field(..., example="Steve")
surname: str = Field(..., example="Rogers")
age: int = Field(..., example=102)
@app.get("/users")
async def get_users_manual_filters(
# manually define filters
filters: FilterValues = Depends(create_filters(name=str, surname=str, age=int)),
) -> List[UserOut]:
pass
@app.get("/users")
async def get_users_auto_filters(
# or automatically generate filters from pydantic model
filters: FilterValues = Depends(create_filters_from_model(UserOut)),
) -> List[UserOut]:
pass
Currently, fastapi-filters
supports SQLAlchemy
integration.
from fastapi_filters.ext.sqlalchemy import apply_filters
@app.get("/users")
async def get_users(
db: AsyncSession = Depends(get_db),
filters: FilterValues = Depends(create_filters_from_model(UserOut)),
) -> List[UserOut]:
query = apply_filters(select(UserOut), filters)
return (await db.scalars(query)).all()
