URL 在 Django 中使用参数和不使用参数

Question

I am using Django for my project, and I want to render thank-you page. But it should be with or without parameters.

urls.py

urlpatterns = [
    ....
    path(r'thank-you?t=<type>?n=<name>', thank_you_view, name='thank-you'),
    ....
]

it is working fine for urls like: http://127.0.0.1:8080/thank-you%3Ft=teacher%3Fn=Ajay,%20Gaikwad Template make use of parameters.

but not working for url without parameters like: http://127.0.0.1:8080/thank-you Default template will be rendered here.

also I tried some regex

path(r'thank-you(?t=<type>?n=<name>|'')', thank_you_view, name='thank-you'), But it not working.

If you use below view and render context with template then it will work.

views.py

def thank_you_view(request, *args, **kwargs):
    context = {kwargs['type']: kwargs['name']}
    return render(request, "light/thank-you.html", context=context)

Edit:

• Is it any way to use regex in url so it will work for both ways?
• Or can we make parameters as optional?

Once you define path parameters, Django is expecting it in the URL. Else you can get it as query parameters. You're mixing up query and path parameters.
