Get route value from inside a decorator

In Flask, how do you get a route value (eg. '/admin') inside a decorator? I need to pass certain string to the DB depending on which route was used (and they all use the same decorator).

@app.route('/admin')
@decorator
def admin(data):
     do_something(data)

I couldn't find information about how to do it in Python. Is it possible?

You can define a new decorator which get the current route path then do something with it:

from functools import wraps
from flask import request

def do_st_with_path(f):
    @wraps(f)
    def decorated_function(*args, **kwargs):
        path = request.path
        do_anything_with_path(path)
        return f(*args, **kwargs)
    return decorated_function

And for every route, add this decorator as the second one:

@app.route('/admin')
@decorator
def admin(data):
     do_something(data)

Another solution without adding a new decorator: use before_request. Before each request, you can also check the route path:

@app.before_request
def before_request():
    path = request.path
    do_anything_with_path(path)
