I want to route to the specific post like this /knowledge/:of_type/:id . get '/knowledge/:of_type/:id', to: 'posts#show', as: 'post' but the :of_type isnt enforced i can literally put anything on there . how can i make it that it adds whatever is in of_type into the url structure?

foo.rb

here is the schema of my post model
