Example Code

from typing import Optional, List

from fastapi import FastAPI, Depends, Query
from pydantic import BaseModel

app = FastAPI()


class Item(BaseModel):
    name: str
    description: Optional[str] = None
    price: float
    tax: Optional[float] = None
    relates_to: List[int] = Query(...)


@app.get("/items/")
async def sample_get_items(
    item: Item = Depends()
):
    return "ok"

Description

This code is based on the samples in the fastapi site.

The problem is in the parameter relates_to . This parameter not appears in the /docs as a parameter because this is of the tytpe List[int]

I need, by this way, declaring parameters for a endpoint thought a pydantic.BaseModel, that have possibility to receive multiple values.

But the way it’s written in the example, it doesn’t work, either by sending /item/?relates_to=10&relates_to=11&relates_to=12 or /item/?relates_to=[10,11,12] or other way…

How this #question can be transformed in a #issue ?

You are not supposed to have a Query inside the Pydantic model.

I undertand, but is the only way that this works in a Pydantic model (see image) to be simple
