Get current path with name of query params in the path - ruby-on-rails

Question

In a Rails controller, how can I access my current path, but with the query params in the same format as what we have in rails routes ?
So for example, in www.test.com/record/3 the helper I'm looking for would return record/:id.
I've tried request.path but it does not return the name of the param in the URL. It returns the actual path, which is not what I want.

What you're looking for are called dynamic segments (or sometimes named placeholders).
You can get the them programatically for a given request with request.path_parameters.except(:action, :controller).
# route is defined as 'get /:foo/:bar'
irb(main):013:0> app.get '/a/b?x=2'
Started GET "/a/b?x=2" for 127.0.0.1 at 2023-01-11 01:08:53 +0100
Processing by PagesController#home as HTML
Parameters: {"x"=>"2", "foo"=>"a", "bar"=>"b"}
Rendering layout layouts/application.html.erb
Rendering pages/home.html.erb within layouts/application
Rendered pages/home.html.erb within layouts/application (Duration: 0.1ms | Allocations: 7)
Rendered layout layouts/application.html.erb (Duration: 2.7ms | Allocations: 2363)
Completed 200 OK in 4ms (Views: 3.3ms | Allocations: 2675)
=> 200
irb(main):014:0> app.request.path_parameters
=> {:controller=>"pages", :action=>"home", :foo=>"a", :bar=>"b"}
Unlike the params object this doesn't contain parameters from the query string or request body.
