Routed paths must always start with /

Hi

Let’s say I have the following API:

GET /accounts  - list of accounts
POST /accounts  - create account
GET /accounts/{id} - get account by id
DELETE  /accounts/{id} - delete account

then I would make a module accounts with APIRouter

in main.py

app.include_router(accounts.router, prefix="/accounts")

and in accounts.py

router = APIRouter()

@router.get("")
def list_accounts():
    ...

@router.post("")
def list_accounts():
    ...

@router.get("/{id}")
def get_account(id:str):
    ...

but I’m getting an error “Routed paths must always start with /”

if I add to router “/” - then my resources will look like GET /accounts/ , POST /accounts/ (but I do not want slash at the end…)

Basically the idea is to put 5-10 methods inside module and all should start with /accounts

how should i solve this ?

Thank you, everyone, for the discussion here!

Thanks @vitalik for the PR! More comments on the PR itself: https://github.com/tiangolo/fastapi/pull/415#issuecomment-524591290

You can now use this in FastAPI 0.36.0 with an empty path (""). 🎉 🚀

I’ll close this now, but feel free to add more comments or create new issues.

It does seem sort of awkward that using prefix prevents ‘trailing slash’ naked endpoints, as OP mentioned.

Good: /cats Bad: /cats/

(subjectively speaking)
