Hey there, is there a way to error if there are additional keys in the json body which are not contained inside the struct wrapped around web::Json?

Currently we have the problem that a typo or whatever confusion results in a silent fail

because all our fields are optional

I just try to write a handle with Result = ResponseActFuture, and return a Box::pin, but idk how can i send an actor Request and wait its result to operate a return value in async block. Anyone know?

I posted a little trait I made for error handling in actix-web that some of you might find helpful: https://old.reddit.com/r/rust/comments/ozc0m8/an_actixanyhow_compatible_error_helper_i_found/

Looking for an examples how to use query extractors and customising its errors messages. We need to capture query validation errors and translate it to our custom Error response.
Found this: https://docs.rs/actix-web/4.0.0-beta.8/actix_web/web/struct.QueryConfig.html but some examples would definitely help as still in learning mode -> rust and actix.

is there any easy way to make custom session stores in actix_session?

Actix files are working in development. Tested in target folder it is working. But some how not working inside docker. I m literally out of ideas. Any help?

Fabio

@f4bio:matrix.org

Probably need way more information...

Works for me

Do you have a sample application?

Kunjan Dalal

@kunjee17

It works for me out side of docker.

But 404 inside docker.

SS is from docker image it self.

server and open_api both are at same locaiton

location

Fabio

404 should give you some direction where to look at

also, put ENV RUST_LOG=debug in your Dockerfile and run with docker run -it --rm yourimage:latest

like I said, it works fine for me. has to be somewhere at your implementation

without demo/sample project with your code its quite hard to help you much further

there is also a working example in official actix-examples

The container probably doesn't have access to the files. They are not compiled into the binary.

Kunjan Dalal

@kunjee17

They are not . I m copying seperately

Code is pretty simple.

use actix_files::Files;
use actix_web::web;

pub fn config(cfg: &mut web::ServiceConfig) {
    // cfg.service(docs).service(spec);
    cfg.service(Files::new("", "./open_api").index_file("index.html"));
}

I m not doing anything fancy

And open_api folder is at root level

out side of src

Fabio

@f4bio:matrix.org

[m]

maybe try:

    cfg.service(Files::new("/", "./open_api").index_file("index.html"));

I'm not sure what happens if mount path is empty

Also wasn't there something like show_file_listing() to list content of folders?

Files::new probably expects a file as second param?

I'm on mobile right now, can't check. Sorry

Kunjan Dalal

@kunjee17

Thanks for help @f4bio:matrix.org . No hurries. I m returning json as hardcoded string for now. I ll check out your solution as well.

Is actix actors still a way to run long running tasks? I have a heay duty process which requires some parallel processing. The API endpoint is actix-web and once I receive a request I need to run parallel jobs to get the data. The data is then sent back as a result to API end point. I was thinking to create an actor which can then run in parallel with main thread. Is it right way of going about it?

uh. I hope somebody with deeper knowledge than me (than I? :D) can answer that

I tried something similar a while ago

used something similar to this (first google result ;D)

kind of worked. ultimately I switched to schedule based tasks

Hi, how can I serve static files without the html extension. aka clean URLs? This is required for some web frameworks, I'm trying to serve nextjs after exporting the build. I already have

.service(fs::Files::new("/", "frontend/dist").index_file("index.html").prefer_utf8(true)

Basically I want the behaviour as if the /foo.html was served from /foo/index.html

Hey there! I'm trying to learn about websockets, and I've been referring to the docs but the example code is out of date!

https://github.com/actix/examples/tree/master/websockets/websocket

Uses actix v0.10 instead of the latest, and there is seemingly a breaking change to the example code when trying to run with 0.12

Hi there! Is there anyone know how or the scripts to deploy a latest beta version actix server to Google Cloud Run? I've tried a simple hello world server, works well on the local, but the deployment was timed out.

Hi, I am rather new with Rust and actix.
I have an actor under test an it sents a message to an other actor which is mocked with the Mocker.

let mocker = Mocker::<RgbSensor>::mock(
                Box::new(move |_msg: Box<dyn Any>, _ctx| {
                   let res = match _msg.downcast::<Start>() {
                        Ok(_) => {Some(())},
                        Err(_) => {
                            //Error should fail the test
                          None::<()>
                        }
                    };

                    Box::new(res)
                })
            );

When None is returned the Mocker produce a panic, this panic don't let the test fail.
How can it achieved that the test get fail, when the actor under test sends a wrong message or the message is never sent. Hope somebody can point me to the right direction.
