app_template_url_foris a little helper function that takes into account the deployment target when building urls. It inserts the project's slug/path prefix when building for staging or prod.Note that I'm overriding Flask's
url_forwithapp_template_url_forin app.py.Also added
static_folder='www/assets'to the Flask instance so that{{ url_for('static', filename="some_file.png") }}works properly when some_file.png is in www/assets/.I wrote this because I couldn't find a way to configure the Flask object to do this for me. Maybe I'm missing something. Let me know what you think!
