In flask, how do I serve images that are not in the static folder?
I currently save the user uploaded photos on a directory that is outside the flask folder (On openshift
, image currently saving in the data folder under app-root/data
and the flask files are in app-root/repo/
).
In my templates, how do i serve the image files ?
Using url_for
, how do i reference these image files that are outside the flask folder?
- data/
|
-- uploads/
- repo/
|
-- app/
|
-- __init__.py
As you can see the data folder outside the flask app folder. How do i generate links to files stored in data/uploads
(one level up) from the flask app directory is the question ?
You have the send_from_directory function that does what you want, what I would do is declare a constant called MEDIA_FOLDER with the path where the media files are located and then, the only thing you need to do is to call the function like this:
from config import MEDIA_FOLDER
@app.route('/uploads/<path:filename>')
def download_file(filename):
return send_from_directory(MEDIA_FOLDER, filename, as_attachment=True)
Then, to invoke it, you just do this:
{{ url_for('download_file', filename='dogs.jpg') }}
