And I have several endpoints which gets called from the above lambda function, do their job and return the response accordingly like this:

@router.get("/index")
def sample_endpoint(request: Request):
   try:
       query_params= request.query_params
       body = request.body
       # ....
       return Response(
           status_code = 200,
           content=json.dumps(response_body)
       )
   except Exception as ex:
        # ... process exception ...

Instead of accepting generic Request object and extract query_params and body data myself, I would like to use more explicit parameters such as item_id: int, customer_name: str, and so on for each endpoints. Since I am using middleware decorator for the lambda function to forward the request to path provided, I am not sure how to do it other than passing in the whole Request object from lambda function. Would this be possible?

Everyting works fine when installing with pip -r ..., BUT when tha package is built as wheel, then

ERROR: Could not find a version that satisfies the requirement keras-contrib (from superduperpack==0.3.5) (from versions: none)

Help appreciated!

Hi everyone, how is everyone doing?

I have a question, it will be nice if some one can point me in the right direction.

How can share some global variable among different workers of the fastapi

I have lot of CPUs in my machine and I need multiple workers to utilize all the CPUs efficiently.

However when I am using multiple workers, I am not able to share the globals variables among different workers..

Thanks for your help.

RES

@madkote

@Max2ben_twitter redis?

Akhilesh Kumar

@Max2ben_twitter

Thanks @madkote I have not tried redis but I can give it a try.

is there any other solution for sharing the variables?

Nicolas Gilles

@ngilles

redis will work, and as a bonus, even if you launch further instances (even on different machines)

RES

@madkote

@Max2ben_twitter google -> "python sharing the variables"

Nicolas Gilles

@ngilles

@Max2ben_twitter depends on what kind of global variable you're looking for.... a constant? or mutable?

Akhilesh Kumar

@Max2ben_twitter

its a mutable

Nicolas Gilles

@ngilles

I'm not sure how workers are isolated ... I'm assuming different processes... so maybe the solution is shared memory or something like that, in which case, redis might actually be an easier solution

if they are just threads, well, an object and lock and you should be fine

Akhilesh Kumar

@Max2ben_twitter

ok. Thanks @ngilles and @madkote

Workers are processes

Nicolas Gilles

@ngilles

though not sure how to mix that with the async nature actually :D

@alecgerona

Anyone has an idea how to make mypy happy in this instance?

Marcelo Trylesinski

@Kludex

can I see the two classes involved on that union? @alecgerona

Valon Januzaj

@vjanz

@alecgerona I also had similar issues

What you have to do is to look at the infered return types, and then to do some checking or assertion ( not recommended) because it can cause problems in prod.
Do some "strict" type checking yourself and then mypy knows that it had passed that kind of check, and the error will dissapear

Yarn build is creating the files inside /dist but my fastapi is trying to access "GET /js/app.2e733260.js HTTP/1.1" 404 and getting 404

I did app.mount("/dist", StaticFiles(directory="dist"))

Hi all, using openapi_url and proxy my fastapi docker container behind a nginx server my apis are correctly available and openapi.json is also available at https://address/subaddress/api/v1/openapi.json. https://address/subaddress/docs give me following error:

Fetch error
NetworkError when attempting to fetch resource. /api/v1/openapi.json

What's wrong ?

Solved using openapi_prefix="/subaddress", docs is available.
Perhaps I've another issue: when trying to use autheticate to access to protected routes in /docs page i've the following error: auth errorTypeError: NetworkError when attempting to fetch resource.
Any advice? Thanks in advance!

I was wondering if anyone solved how to convert sqlalchemy records into pydantic models.

thank you @eseglem , did conda install uvicorn.

Hi guys, beginner here, I am wondering if anyone can help me with this:

I am getting this:

@carlomazzaferro

Hi all, QQ: the /openapi.json endpoint does not contain the example section https://swagger.io/docs/specification/adding-examples/ in the ['endpoint_name']['schema']['requestBody'], however my FastAPI endpoint clearly has a generated one in the Swagger. How can I get it? Need to programmatically fetch it

@phaltoe85_twitter Tuples are not supported by the OpenAPI spec: tiangolo/fastapi#466 , ran into this recently as well :)

Pedro

@phaltoe85_twitter

thanks @carlomazzaferro!

Carlo Mazzaferro

@carlomazzaferro

@Cleptomania not sure if it fits your needs but https://fastapi.tiangolo.com/advanced/path-operation-advanced-configuration/#exclude-from-openapi you can exclude a certain path

Just to note, my models are dynamically generated so I can't manually set the schema_extra in my pydantic models

Guys, how do you ignore alembic directory from mypy?

Andreas Franzén

@triptec

@vjanz ```

[mypy-app.tests.*]
ignore_errors = True

but change the .tests. to .alembic. perhaps

Valon Januzaj

@vjanz

So the tests in this case refers to the directory right
