Dynamically generate Flask routes

Question

I am trying to dynamically generate routes in Flask from a list. I want to dynamically generate view functions and endpoints and add them with add_url_rule.

Answer 1

Not too familiar with Flask, so it is possible that there is a cleaner way to do this. (If someone who is knowledgeable about Flask thinks that my method is inherently wrong, I'll gladly delete my answer if they explain why in a comment.) Now that I got that disclaimer out of the way, here are my thoughts:

app.route("/") is a decorator function. The @ notation is just syntactic sugar for something like index = app.route("/")(index). Therefore, you should be able to do something like this...

routes = [
    ("/", index),
    ("/about", about)
]
for route, view_func in routes:
    view_func = app.route(route)(view_func)

which would allow you to create the Flask routes from dynamically created routes and functions.
