expiring an action cache

[mzaragoza]

I added this to my project and its working fine but I am having a problem expiring the cache

my controller looks like

class PostsController < ApplicationController
  caches_action :show

   def show 
     @post = Post.find(params[:id])
   end
end

it works fine when I visit different post but when a post gets updated it does not reflect that

Thanks

@mzaragoza you are right, the documentation of this gem is not complete. You have to use a so called Sweeper.

Have a look at the rails-observers README.

Можно обновлять так:
expire_action controller: "posts", action: "show"
Но данный метод не работает из другого контроллера!
Может кто подскажет как его вызвать из другого контроллера?

@zedtux
rails-observers is not working for rails 5.. end mongoid

👍 It would be nice to have a cache_key type of control over the expiration of the cache at the controller level.
