[bobwatcherx]

I want to ask . how to copy the resulting file that I uploaded to the uploads folder
code

import shutil
from nicegui import ui

def on_upload(event):
    # Mendapatkan nama file yang diunggah
    print(x)


    file_name = event.name
    print(e)
    # Menyalin file ke direktori uploads
    src_path = event.path
    dst_path = './uploads/' + file_name
    shutil.copy(src_path, dst_path)
    
    ui.notify(f'{file_name} uploaded and saved to uploads folder')
    
ui.upload(on_upload=on_upload).classes('max-w-full')

ui.run()

thanks

Please see #283 for a related discussion.
There is no path in the upload event. So you can't copy the file but need to write a new one with the data from event.content.
Or you use something like the local file picker.

I'm still confused why the upload file is useless for uploading. instead use something else namely local file picker . Then what is the function of the upload file if u can't do it Upload files

Local file picker is a special solution for when NiceGUI is running on the client's machine (where your browser runs) and needs access to the file path, e.g. for analyzing the file without loading it into memory all at once. This is not possibly by "uploading" the file via normal web tools like Quasar's uploader.

In most cases, however, uploading (i.e. transmitting the raw file data) is just fine. The original file path gets lost, but usually the server is interested in the content rather than its original location. A major benefit is that the server (NiceGUI) can run on a different machine than the client (the browser). If you, e.g., implement an online image conversion service with NiceGUI, you can conveniently use ui.upload. The file needs to be sent to the server anyway and you don't want to get information about the client's file system.

@falkoschindler Since we have now implemented the standalone mode (coming with next release 1.2.0), running the frontend on the same machine as the backend will become a more common use-case.
