I want to get app instance in my router file , what should I do ?
My main.py is
...
app = FastAPI()
app.machine_learning_model = joblib.load(some_path)
app.include_router(some_router)
...
Now I want to use app.machine_learning_model in some_router's file , what should I do ?
You could access the app instance using request.app, as shown below:
from fastapi import Request
@router.get("/some_route")
async def some_router_function(request: Request):
model = request.app.machine_learning_model
