Flask change value route returns

Question

If I have a route:

@app.route("/api")
def api():
    return some_val

And then some_val changes, I need to restart the server for the route to display the new value (I read/write it to a file). How do I make routes dynamically update their content? Is it even possible? Thanks!

How you get `some_val`? Try to calculate it inside of the function `api` — Ramon Medeiros, Feb 03 '20 at 10:08
`some_val` is a list of dicts, and when the user adds one from the frontend, and reloads the page, now each dict is duplicated inside the list. — PG Cubing, Feb 03 '20 at 10:12

this might do the trick!

import random
@app.route("/api")
def api():
    return str(random.random())

or this might be fun! don't forget to install fortune in linux!

import subprocess
@app.route("/api")
def api():
    return subprocess.check_output('fortune')

Not quite, because I want to return a variable, is there a function that forces the route to reload? – PG Cubing Feb 03 '20 at 10:17
I guessing mean debug mode `FLASK_DEBUG=1 flask run`, when code auto reloads. – rho Feb 03 '20 at 11:09
