Is Actix Multipart Not Yet Implemented ?

[sutantodadang]

in the server function i got this code

use leptos::*;
use server_fn::codec::{MultipartFormData,MultipartData};
use crate::models::animal_model::{Animal, RegisterAnimal};
use server_fn::codec::GetUrl;

#[cfg(feature = "ssr")]
use crate::database::db::{get_animals_by_id,get_all_animals};

#[server(name = CreateAnimal, prefix = "/api/v1",input=MultipartFormData)]
pub async fn register_animal(form_data: MultipartData) -> Result<(), ServerFnError> {
    #[cfg(feature = "ssr")]
    {
             
     
        logging::log!("Form Data: {:?}", form_data);
        let mut data = form_data.into_inner().unwrap();

   
         let mut count = 0;
         while let Ok(Some(mut field)) = data.next_field().await {
             let name = field.name().unwrap_or_default().to_string();
             while let Ok(Some(chunk)) = field.chunk().await {
                let len = chunk.len();
                count += len;
             
         }
        }

        logging::log!("Total bytes uploaded: {count}");
        Ok(())
    }
    #[cfg(not(feature = "ssr"))]
    {
        Err(ServerFnError::ServerError("Server function called from client-side.".into()))
    }
}

and client code like this

let on_file_change = move |ev: web_sys::Event| {
        let input = event_target::<web_sys::HtmlInputElement>(&ev); 

        let files = input.files();
        
        if let Some(files_list) = files {
                let mut files_vec = Vec::new();
                for i in 0..files_list.length() {
                    if let Some(file) = files_list.item(i) {
                        files_vec.push(file);
                    }
                }
                set_selected_files.set(files_vec);
            }
        
    };

    let animal_action = create_action(|data: &web_sys::FormData| {
        let data = data.to_owned();
        async move {
         let multipart_data = MultipartData::from(data);
         register_animal(multipart_data).await
        }
    });

    // Handle form submission
    let on_submit = move |ev: ev::SubmitEvent| {
        ev.prevent_default();
        set_pending.set(true);

        let form_data = web_sys::FormData::new().unwrap();
        for file in selected_files.get().iter() {
            form_data.append_with_blob("images[]", file).unwrap();
        }

        let _ = form_data.append_with_str("animal_name", animal_name.get().as_str());
        let _ = form_data.append_with_str("animal_status", animal_status.get().as_str());
        let _ = form_data.append_with_str("animal_type", animal_type.get().as_str());
        let _ = form_data.append_with_str("description", description.get().as_str());
        let _ = form_data.append_with_str("expected", expected.get().as_str());

        animal_action.dispatch(form_data);

        set_pending.set(false);
    };

but when try to upload images it get error on console like this

Total bytes uploaded: Server(Multipart { state: Mutex { data: MultipartState { buffer: StreamBuffer, boundary: "----WebKitFormBoundaryVNmRVgbdoFQeV0tP", stage: FindingFirstBoundary, next_field_idx: 0, curr_field_name: None, curr_field_size_limit: 18446744073709551615, curr_field_size_counter: 0, constraints: Constraints { size_limit: SizeLimit { whole_stream: 18446744073709551615, per_field: 18446744073709551615, field_map: {} }, allowed_fields: None } }} })

The not yet implemented points to this line in server_fn
https://github.com/leptos-rs/leptos/blob/main/server_fn/src/request/actix.rs#L94

So yes, apparently it is not yet implemented.

Any interest in making a PR?

[sutantodadang]

sure, i will create the PR
