Variable In Flask Static Files Routing [url_for('static', Filename='')]

I'm making a simple music app. I want to allow users upload their audio files and I have a page where I'm planning to show all songs. I've created a template, and the structure loo

Solution 1:

I don't believe you can nest template tags like that. But you also shouldn't need to.

<imgsrc="{{ url_for('static', filename='uploads/users/') }}{{ song['artistName'] }}/{{ song['pathToCover'] }}">

You can see why this works from the following example:

>>>from flask import Flask, url_for>>>app = Flask(__name__)>>>with app.test_request_context():...print url_for('static', filename='uploads/users/')
/static/uploads/users/

So then you just need to add the artistName, /, pathToCover

Solution 2:

I think you can do

<imgsrc="{{ url_for('static', filename='uploads/users/'+ song['artistName']+'/'+ song['pathToCover'])}}">

It works for me :)
