Creating a prefix route in rails

Question

I want to create URLs of the form /suffix-<slug> with rails but I can't see how to map that on the routes.rb, how can I do that?

Answer 1

Well, one way to achieve that is to consider the prefix as part of the id and then handle removing it in the controller:

routes.js

# Only for one place
post '/:id' , to: 'books#create', id: /prefix-.*/

# Same format in multiple places
constraints(id: /prefix-.*/) do
  post '/:id' , to: 'books#create'
  ...
  # Works with resources as well
  resources 'objects'
end 

Controller

def create
  params[:id].slice! "prefix-"
  ...
end
