How to filter resources in Rails?

Question

Currently, I'm building a blog in Rails and I am being curious is there a right way to display resources in the following manner?

In this case you may be able to list all the posts, and if needed, separate category posts.

You'd normally say - use scopes, however I'm not sure scopes are gonna produce the following adressess: /blog/features, /blog/releases.

So, how can I do this?

Answer 1

#config/routes.rb
resources :blogs, path: "blog" do 
   get ":category", to: :index, on: :collection #-> url.com/blog/:category
end

#app/controllers/blogs_controller.rb
class BlogsController < ApplicationController
   def index
       @posts = params[:category] ? Post.joins(:category).where(category: {name: params[:category]}) : Post.all
   end
end

#app/views/posts/index.html.erb
<% @posts.each do |post| %>
   ...
<% end %>
