Rails 4-路径中的哈希被错误地渲染

Question

I have this line of code in routes.rb

get 'products#:id' => 'products#index', as: :products_hash

It works, but the problem is that the hash symbol (#) gets rendered as %23.

http://localhost:3000/products%2368

This is what it should be:

http://localhost:3000/products#68

How can I achieve this? Thanks!

Rails

I feel you're missing the point of Rails' routing system , which is that you are meant to construct it around objects (hence why you call resources :controller etc).

Although I don't understand why you're defining the route you are, I'll give you some ideas. There is a "wildcard" setting for your routes in Rails, which allows you to define & pass parameters to your application out of the scope of the typical "CRUD" based applications:

#config/routes.rb
get 'products#*id' => 'products#index', as: :products_hash

This will give you the ability to send requests to the following route:

<%= link_to "Product", products_hash_path("68") %>

You'd then be able to call the param in the controller:

#app/controllers/products_controller.rb
class ProductsController < ApplicationController
   def index
      id = params[:id]
   end
end
