Soy nuevo con s3 e intento cargar algunos archivos, pero The system cannot find the file specified: <hashed_file_name>.jpg Entiendo el problema. Cuando el archivo se guarda en la raíz, todo está bien. Pero no quiero guardar el archivo. Quiero subirlo directamente después de la action en el form .

 def upload_to_s3(file_to_upload, s3_upload_folder): s3 = boto3.resource('s3', aws_access_key_id=app.config['ACCESS_KEY_ID'], aws_secret_access_key=app.config['SECRET_ACCESS_KEY']) s3.meta.client.upload_file(file_to_upload, app.config['BUCKET_NAME'], s3_upload_folder) def _user_img_folder(form, file_name): username = session['name'] vacation_name = slugify(form.test_name.data) directory = os.path.join(username, test_name) directory = os.path.join(UPLOAD_FOLDER, directory) return directory + '/' + file_name @app.route('/post', methods=['GET', 'POST']) def test(): if _is_image(): uploaded_images = request.files.getlist('photo') for image in uploaded_images: processed_image_name = _hash_image_name(image) # Returns hashed filename with extension directory = _user_img_folder(form, processed_image_name) upload_to_s3(str(processed_image_name), str(directory)) return render_template('test.html', form=form, error=error)

Gracias por tu ayuda.
