After struggling to get dependencies inside of middleware I learned that you can make global dependencies at the app level. I used this to set the user on every single route of the application without needing Depend on getting the user on each route.
``` python
from fastapi import Depends, FastAPI, Request
def get_db_session():
print("Calling 'get_db_session(...)'")
return "Some Value"
def get_current_user(session=Depends(get_db_session)):
print("Calling 'get_current_user(...)'")
return session
def recalculate_resources(request: Request, current_user=Depends(get_current_user)):
print("calling 'recalculate_resources(...)'")
request.state.foo = current_user
app = FastAPI(dependencies=[Depends(recalculate_resources)])
@app.get("/")
async def root(request: Request):
return {"foo_from_dependency": request.state.foo}
```
