Fastapi: Class issues, registering Self as a query string.

[TobiWtf]

from fastapi import FastAPI
from fastapi.responses import HTMLResponse, JSONResponse, PlainTextResponse, Response
import uvicorn

class App:

    Server: FastAPI = FastAPI()

    def __init__(self):
        pass

    @Server.get("/home", response_class=PlainTextResponse)
    async def Home(self):
        return "e"

    def Run(self, *args, **kwargs):
        try:
            uvicorn.run(self.Server, **kwargs)
        except:
            return self


App().Run(host="0.0.0.0", port=42069)

Using this code, when i attempt to run it, and make a request to GET/home/ i get this error client side.

{
    "detail": [
        {
            "loc": [
                "query",
                "self"
            ],
            "msg": "field required",
            "type": "value_error.missing"
        }
    ]
}

and this error server side

INFO: 192.168.1.88:58374 - "GET /home HTTP/1.1" 422 Unprocessable Entity

I know the reason im getting this error is because its recognizing the variable self as a missing query, however im not sure how to fix this without removing it from the class (which i dont want to do) Thanks for any help yall can provide :)).

Hi,
self = None can fix your problem.
i mean:

    async def Home(self=None):
        return "e"

I didn't understand what you were doing

but I don't understand what you're doing :)

It's just returning the letter e, as a test.

However that likely won't fix the issue, because, it won't be able to call on the rest of the class, as it will be a bull value rather than the class object.

I know,
but in your way, you should initial the self (your Object) or hide it(Null). [i think]

Do you need an optional parameter?

[langengel]

Your definition of home is a routing annotation. It's not a member of your App object. So there is no self.

Is it possible to add the app object on top of it?

We don't recommend doing this.

@langengel why is it not recommended?

I found multiple solutions, this one is definitely the most helpful. I also found that, if I don't need the class I can make it a static method and stack the decorators.
