There are 2 functions or views located in the same file version.py, one for upload the other for downloading that file. The issue is that the send_file function keeps changing directories while opening the file.
Code 1:
File Upload function:
binfile = form.binfile.data
filename = secure_filename("arduino.bin")
#without the app folder
binfile.save(os.path.join(
app.config['UPLOAD_FOLDER'],
device_names.farm_id,
device_names.mqtt_id,
filename))
flash('File Uploaded', 'success')
File Download Function:
file_path = os.path.join(
app.config['UPLOAD_FOLDER'],
farm_id,
device_id,
'arduino.bin')
print(file_path)
response = make_response(send_file(
file_path,
mimetype='application/octet-stream',
as_attachment=True
))
response.headers['x-MD5'] = md5(file_path)
print(response.headers)
return response, 200
Here the file gets uploaded to the project root folder. When I send a request for this file, I get this error:
[Errno 2] No such file or directory: ‘/home/maxwell/Desktop/python/aquaponics-monitor/app/firmware-manager/FARM0/node2/arduino.bin’
When I manually move the file to the 'app' folder I get no errors and a 200 response code while requesting. So I assume that the function is looking for the file inside the 'app' folder. I changed the upload location by adding 'app' to the path while uploading.
Code 2: File Upload Function:
binfile = form.binfile.data
filename = secure_filename("arduino.bin")
#app folder included
binfile.save(os.path.join(
'app',
app.config['UPLOAD_FOLDER'],
device_names.farm_id,
device_names.mqtt_id,
filename))
flash('File Uploaded', 'success')
The file download function is the same as code 1. For this code I get this error:
[Errno 2] No such file or directory: ‘firmware-manager/FARM0/node2/arduino.bin’
The file download function now looks in the project root folder. I manually moved the file to the root folder this time and I again get a status code 200 and no errors when I send a request for it. The only code change I made in the entire application is adding 'app' to the path in the File Upload function. Why is this happening?
