I sometimes have a class based view which has a GET and a POST method, for
example a ListView which shows some objects with a POST form to create
something out of it.
In the documentation
(https://docs.djangoproject.com/en/5.0/topics/http/urls/) I did not find a
simple way of doing that. Asking GitHub Copilot suggested me adding a
question mark at the end to mark a parameter as optional which does not
work.
**I found myself 2 solutions:**
1. using regex which looks cumbersome just for marking something as
optional:
{{{#!div style="font-size: 80%"
Code highlighting:
{{{#!python
re_path(
r"^activate/(?P<activation_token>[^/]+)?$",
views.UserActivationView.as_view(),
name="user_activation",
)
}}}
}}}
2. using 2 paths: one without a parameter and one with a parameter:
{{{#!div style="font-size: 80%"
Code highlighting:
{{{#!python
path(
"activate/",
views.UserActivationView.as_view(),
name="user_activation",
),
path(
"activate/<str:activation_token>/",
views.UserActivationView.as_view(),
name="user_activation",
)
}}}
}}}
For this ticket, I want to suggest a) improve the documentation with a
simple example how to do that and/or b) can this be simplified in django
by adding for example a question mark at the end like "/<int:some_id?>/"
or "/<int?:some_id>/":
{{{#!div style="font-size: 80%"
Code highlighting:
{{{#!python
path(
"activate/<str:activation_token?>/",
views.UserActivationView.as_view(),
name="user_activation",
)
}}}
}}}
