Username field in the flag report is blank

[gsachdev-adeptia]

Describe the bug

The flag log file created from Gradio is having username column but value is empty.

Is there an existing issue for this?

Reproduction

#login function
def same_auth(username, password):
return username == password

#setup gradio interface
iface = gr.Interface(fn=chatbot,
inputs=gr.components.Textbox(lines=7, label="Enter your text"),
outputs="text",
title="testing", allow_flagging="manual",flagging_options=["correct","wrong","ambiguous"])

#launch gradio
iface.launch(share=True ,auth=same_auth)

Thanks @gsachdev-adeptia for reporting! This is indeed broken, though we have a fix here: #4135

[gsachdev-adeptia]

Thanks @abidlabs. Do you know when it will be available for revalidation?

[abidlabs]

I think we'll merge in main soon (in the next day or so). I'm not sure when we'll release to pypi but you can install gradio from main by following the instructions here: https://gradio.app/docs/main

[abidlabs]

The fix is on main if you'd like to test it out.

I uninstall the gradio and installed it from the main branch as you indicated. Still not seeing any value filled in for the username in the flagged file. Do I need to do anything additional to have that written in the flagged file?

[abidlabs]

I tested with this code and it's working for me on main:

import gradio as gr
#login function
def same_auth(username, password):
    return username == password

#setup gradio interface
iface = gr.Interface(fn=lambda x:x,
    inputs=gr.components.Textbox(lines=7, label="Enter your text"),
    outputs="text",
    title="testing", allow_flagging="manual",flagging_options=["correct","wrong","ambiguous"])

#launch gradio
iface.launch(auth=same_auth)

Can you try it and see if it works for you? You might need to delete the log.csv file

I am still getting blank user name. Is the below pip to get from main branch correct
pip install https://gradio-main-build.s3.amazonaws.com/2cf13a1c698afed7f4418bc705902fa7868c6890/gradio-3.29.0-py3-none-any.whl

I suspect the above link is not correct.

[abidlabs]

Please try:

pip install https://gradio-main-build.s3.amazonaws.com/ccdaac1395238eb9c11dacb5710e78de19c1c70e/gradio-3.29.0-py3-none-any.whl

[gsachdev-adeptia]

It works now. I validated. Thanks for the quick fix.

This is not working with Blocks. User Name is still blank.

code to reproduce:

import numpy as np
import gradio as gr

def sepia(input_img, strength):
    sepia_filter = strength * np.array(
        [[0.393, 0.769, 0.189], [0.349, 0.686, 0.168], [0.272, 0.534, 0.131]]
    ) + (1-strength) * np.identity(3)
    sepia_img = input_img.dot(sepia_filter.T)
    sepia_img /= sepia_img.max()
    return sepia_img

callback = gr.CSVLogger()

with gr.Blocks() as demo:
    with gr.Row():
        with gr.Column():
            img_input = gr.Image()
            strength = gr.Slider(0, 1, 0.5)
        img_output = gr.Image()
    with gr.Row():
        btn = gr.Button("Flag")
        
    # This needs to be called at some point prior to the first call to callback.flag()
    callback.setup([img_input, strength, img_output], "flagged_data_points")

    img_input.change(sepia, [img_input, strength], img_output)
    strength.change(sepia, [img_input, strength], img_output)
    
    # We can choose which components to flag -- in this case, we'll flag all of them
    btn.click(lambda *args: callback.flag(args), [img_input, strength, img_output], None, preprocess=False)

demo.launch()

Gradio version: gradio-3.37.0

Can someone please help.
Basically we need to capture the user accessing the app in backend db.

@RNBharath One year later, I suspect you've already sorted this out, but I was running into a similar problem today.

For anyone encountering this problem in the future, it looks like you need to explicitly pass the username/request to CSVLogger, similar to the code below:

flagger = gr.CSVLogger()

def flag(
    component_field_1,
    component_field_2,
    request: gr.Request  # <-- IMPORTANT
):
    flagger.flag(
        [component_field_1, component_field_2], 
        username=request.username  # <-- IMPORTANT
)

with gr.Blocks() as demo:

    # UI goes here

    flagger.setup( # components # )
    component_1.click(
        flag,    # <-- IMPORTANT
        # components go here
    )

@abidlabs, when following the documentation for the first time, it's very easy to just copy & paste btn.click(lambda *args: callback.flag(list(args)) ... from the example code at the bottom without realizing the need to pass the username as well. Explaining this there may save future developers some trouble.

Hope this helps!
