Hello! I'm wondering if it is possible to let the user download a directory/folder using send_file. When I try to pass in a directory instead of a file to send_file, I get a permission error in Visual Studio Code.

Edit: Solved! Here's how I did it in case anyone ever has this issue.

If you make the folder into a zip file (using shutil.make_archive for example) then you can pass in the zip file to flask.send_file() and it'll work.

Thank you u/weebsnore for your help!

Hi everyone,

For a project, I architectured my Flask app as a package. So at the root, I'm having a config.py
file where I declare the uploads folder like this:

UPLOAD_FOLDER = 'myapp/uploads'

Now from myapp/routes.py, I manage to upload files in the right folder when creating a post, but then I try to declare a route to retrieve these files with:

@app.route('/uploads/')  

def upload(filename): return send_from_directory(app.config['UPLOAD_FOLDER'], filename)

But when displaying the html page where I call url_for('upload', filename=post.picture) I get a 404 on the image... like if Flask was trying to access /myapp/uploads from /myapp

Does someone have an idea?

I tried to hardcode "uploads" into the first parameter of send_from_directory with success. like this:

@app.route('/uploads/<filename>')
def upload(filename):
    return send_from_directory('uploads', filename)

But it's dirty and will break if I ever change the UPLOAD_FOLDER value in config.py. So I'm looking for a clean solution to this.
