Stack Overflow uses routes with the format /:id/:title for questions like this one, which I find to be more memorable than simply a terse ID. I’ve decided that I want this for my new project, a rewrite of this blog in Ruby on Rails 5. Small changes to a model and its routes are required to permit this:
Routes
A post on Stack Overflow led me to a GitHub issue which outlined breaking changes in the to_param object method and a need to glob the route.
get '/ponies/*id', to: 'ponies#show', as: :pony
Model
Add your custom slug:
class Pony < ApplicationRecord
def to_param
"#{id}/#{name.parameterize}"
end
end
And that’s it, simple as.

This is a really helpful post!
I have since discovered a slightly different way to generate Stack Overflow URLs that has a few benefits:
idout from the sluggedtitleresolvemethod which can construct even more complicated urls (if necessary)updateanddeleteroutes still work by maintainingDELETE ponies/:idHere’s the method I’m now using:
# routes.rb resources :ponies do get '(/:name)', action: :show, as: '', on: :member, constraints: -> (req) { req.params[:name] != 'edit' } end direct :ponies do |model| { action: :show, id: model.id, slug: model.name.parameterize } end…which generate these routes:
pony GET /ponies/:id(/:name)(.:format) ponies#show ponies GET /ponies(.:format) ponies#index POST /ponies(.:format) ponies#create new_pony GET /ponies/new(.:format) ponies#new edit_pony GET /ponies/:id/edit(.:format) ponies#edit GET /ponies/:id(.:format) ponies#show PATCH /ponies/:id(.:format) ponies#update PUT /ponies/:id(.:format) ponies#update DELETE /ponies/:id(.:format) ponies#destroyMark Grealish #
Ben I edited your comment slightly for formatting. That looks like a pretty awesome solution for the problem! Shows there’s more than way to climb a cliff.
