I have integrated django-storages in Django Project. for large file sizes, I have used a pre-signed URL to upload files from externally without taking a load on my server.

by pre-signed URL, Files uploaded successfully in the s3 bucket AWS, after uploading the file in s3 I need to update the name of the file in FileField.

Probably you need something like, using the boto3 library to retrieve the file from S3 and os library to rename the file.


import boto3
import os

s3 = boto3.client('s3')

uploaded_file = s3.get_object(Bucket='your-bucket-name', Key='object-key')

new_filename = 'new_file_name.txt'
os.rename(uploaded_file['Body'].name, new_filename)

...

with open(new_filename, 'rb') as f:
    file_obj = File(f, name=new_filename)

    my_model.file_field_name = file_obj
    my_model.save()
