Rails 3.2 friendly url routing by date

Question

I want to implement blog\\news application with ability to:

1. show all posts at root: example.com/
2. show all posts answering some year:

Answer 1

The problem was in post's path helper usage as post_path(post), because first parameter must be year since I use :as => :post in parametrized match in routes.rb.

Nevertheless, to make the entire solution clear here are some actions needed to make that all work proper:

1. You must add proper path helpers names for each match, e.g.

   # Get /posts/2012/07/slug-of-the-post
   match "/posts/:year/:month/:slug", <...>,
     :as => :post_date
   

   Now you can use post_date_path("2012","12","end-of-the-world-is-near") in views.

   Same for posts_path, posts_year_path("2012"), posts_month_path("2012","12") if properly named.

   I advice not to use neither :as => :post in that match nor creating to_param in model file as it can break something you don't expect (as active_admin for me).

2. Controller file posts-controller.rb should be filled with posts that needed extraction and checking of date's correctness before slug. Nevertheless in this state it is OK and breaks nothing.

3. Model file posts.rb should be filled with year and month extraciton in proper format, e.g.:

   def year
     created_at.year
   end
   
   def month
     created_at.strftime("%m")
   end
   

   There is no to_param method really needed as I've noticed already.
