Rails路由多个可选参数

Question

I have a question, how can you make multiple optional params. Fe in my variant, I need similar thing to "/(:first_name || :last_name || middle_name || all_names)". How can I achieve and can I achieve such thing in routes?

Btw, it'd be nice if I can do a lot of multiple params fe:

/(:a || :b || :c)/(:d || :e)/(:n || :m)

Thanks for answering.

You'll have to do all the conditional work in the controller - the routes are there to capture request URLs & direct them to specific functionality (controller/actions).

Thus, your question of using

/(:a || :b || :c)/(:d || :e)/(:n || :m)

... is fundamentally flawed (you can't have condition "or" in Routes).

What you can have is bound parameters :

These are optional params which a route can take, but doesn't have to.

In your case, you'll need to use them to denote the name as passed:

#config/routes.rb
resources :users, path: "" do
   get :first_name(/:middle_name(/:last_name)), action: :show, on: :collection
end

This is the best you're going to get without doing something custom in the routing system... like having slugs or something.
