hqo can i make a correct regex in dajngo? : I need to make regex to make a button witch put me on other website

this is my re_path:
re_path (r'^detaletournament(?P<turnament_id>[0-9]+)/$',detaletournament)

Using the URLconf defined in projekt.urls, Django tried these URL patterns, in this order:

admin/
tir
login
register
usertournaments
turnament
addturnament
takepart
deletetournament
quittournament
mytournaments
webturnament
profile
^detaletournament(?P<turnament_id>[0-9]+)/$
The current path, detaletournament, didn't match any of these.
