How do i link to images not in Static folder in flask

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') }}
