How can I set the 'key' for the 'page_template' inside the views ( not using the decorator)?

[albardn2]

I need to specify the 'key' for the page_template according to the url: /posts/(?P\d+)/.

I am using the same 'page_template' for multiple keys.

is there a way to specify the 'key' according to the pk in /posts/(?P\d+)/.

Thank you:)
