Absolute file path detail in file_upload function

[ashish-kamboj]

When I'm running an application and do the file upload from some other path then it shows only the file name, not the absolute path (it expects that the file should be present in the same directory of application run). So, If I have to read the csv file from some other directory it will give an error through file_upload.

Can you please me how to solve this (How the get the absolute file path)?

You cann't get the full path when uploading a file, it is a browser limitation for security reasons.

When you use file_upload(), you actually don't care about the file path, because you can use the file['content'] to get the file bytes content directly:

import StringIO, csv
file = file_upload('Upload csv', accept='.csv')
csv_fo = StringIO.StringIO(file['content'])  # covert bytes to file object
csv_reader  = csv.reader(csv_fo, )

I can try converting bytes to file object. I think import StringIO is deprecated (it's from io import StringIO). Let me try, actually I have to parse the pdf and docx

If you run your PyWebIO app in a cloud server like ec2, you can't read files from the user machine. That's when you need the file_upload().

If you write a script PyWebIO app, and it only run in your own machine. You can use input() to get the file path by text.
