[BUG]/[FEATURE] multiple path's on the same method results in errors #16
Description
Not quite clear to me if this is a bug or a feature request as I may be doing something out of the ordinary.
Using class based views, my tests return errors using methods (inside cbv) that have multiple path decorators attached to them. When using vanilla FastAPI without cbv the tests pass.
To Reproduce
Credit to @smparekh for the demo below, which I modified slightly to show the issue.
Simple main.py app:
from fastapi import FastAPI, APIRouter
from fastapi_utils.cbv import cbv
router = APIRouter()
fake_items_db = [{"item_name": "Foo"}, {"item_name": "Bar"}, {"item_name": "Baz"}]
@cbv(router)
class RootHandler:
@router.get("/items/?")
@router.get("/items/{item_path:path}")
@router.get("/database/{item_path:path}")
def root(self, item_path: str = None, item_query: str = None):
if item_path:
return {"item_path": item_path}
elif item_query:
return {"item_query": item_query}
else:
return fake_items_db
app = FastAPI()
app.include_router(router)simple test_main.py
from .main import router
from starlette.testclient import TestClient
from .main import fake_items_db
client = TestClient(router)
def test_item_path():
resp = client.get("items/Bar")
assert resp.status_code == 200
assert resp.json() == {"item_path": "Bar"}
def test_item_query():
resp = client.get("items/?item_query=Bar")
assert resp.status_code == 200
assert resp.json() == {"item_query": "Bar"}
def test_list():
resp = client.get("items/")
assert resp.status_code == 200
assert resp.json() == fake_items_db
def test_database():
resp = client.get("database/")
assert resp.status_code == 200
assert resp.json() == fake_items_dbtraceback

Ideally tests work as in vanilla FastAPI without cbv.
