Reversing fastapi routes

[devxpy]

Whenever you want to refer to a server url in code, reverse route fn to URLs / Paths using get_route_url() and get_path_url()

Avoid hardcoding the url paths

# bad
ACCOUNT_URL = str(furl(settings.APP_BASE_URL) / "account" / "")

# good
from daras_ai_v2.fastapi_tricks import get_route_url 
from routers.account import account_route

account_url = get_route_url(account_route)

[devxpy]

PS we use this extensively to build recipe URLs https://github.com/dara-network/ddgai/blob/e7b69bc815eb0ea79dcd9db7bf1262d3b1bb422f/routers/root.py#L729

do you have something in mind for when this will run into a circular import?

e.g. when we define the routes in a parent routes/orgs.py but the actual view logic lives in daras_ai_v2/orgs.py or orgs/views.py.

a common use case would be to redirect to another route.

correction: routers/account.py, not routes/orgs.py

[devxpy]

just import locally inside the function
