Is Django and ftplib connection posible?

Question

I am trying to upload a file from a Django server to another FTP Server using ftplib

This is what I am trying to do in views.py

@background(schedule=1)
def uploadToFTP(folder):
    """
    Async function to upload the images to FTP Server. 
    """
    print("-------------------Start FTP ----------------------------")
    #establish ftp connection

    ftp = FTP(conf_settings.FTP_DOMAIN,conf_settings.FTP_USER, conf_settings.FTP_PASSWORD)

    file = os.path.join(folder, filename)
    
                
    ftp.storbinary('STOR ' + filename, file,102400)     # send the file

I am getting all sorts of errors like this:

ftp.storbinary('STOR ' + filename, file,102400)
  File "/opt/anaconda3/lib/python3.8/ftplib.py", line 489, in storbinary
    buf = fp.read(blocksize)
AttributeError: 'str' object has no attribute 'read'

So I have tried many methods, but nothing works. Is this even posible.

I also tried like this:

with Image.open(os.path.join(folder, i)) as file:
                
                b = io.BytesIO()
                file.save(b, "JPEG")
                b.seek(0)
                #upload activity
                
                ftp.storbinary('STOR ' + i, file,102400) 

Still not successful

1. Here is a manual that you should check first

2. Here is a same question that you should check second

3. Here is an example of correct code:

   from ftplib import FTP
   
   with FTP(
     conf_settings.FTP_DOMAIN,
     conf_settings.FTP_USER,
     conf_settings.FTP_PASSWORD
   ) as ftp:
     with open(os.path.join(folder, filename), 'rb') as file:
       ftp.storbinary(f'STOR {filename}', file)
