Question

I have the following hook in BottlePy:

@bottle_app.hook('before_request')
def update_session():
    # do stuff
    return

And some routes:

@bottle_app.route('/')
def index():
    return render('index')

@bottle_app.route('/example')
def example():
    return render('example')

From within update_session(), how can I determine which route is being called?

I have looked through the documentation to no avail, but surely this is possible?

Answer 1

The request has both a bottle.route and a route.handle entry, both contain the same value:

from bottle import request

print request['bottle.route']

This isn’t documented; I had to find it in the bottle.py source. The value is a Route instance; it has both a .name and a .rule attribute you could inspect to determine which route was matched.

if request['bottle.route'].rule == '/':
    # matched the `/` route.

For your specific example this is perhaps overkill, since you are only matching simple paths, but for more complex rules with regular expression rules this would work better than trying to match the request.path attribute (but it’d be a good idea to give your routes a name value).
