Rendering unique cached page per user in Fragment Caching

[Ankur Kumar]

Hi,

My app has devise authentication for every user. I integrated fragment caching for one of my views which is accessible only on sign-in. 

The cached page saved by one user is accessible by another user. How can I implement a unique key based caching so that cached pages are unique for every user?

I read about some caching methods below but not sure how to create/retrieve a unique cached page.

http://api.rubyonrails.org/classes/ActionController/Caching/Fragments.html

Thanks.

Include the user id in the key string.

Thanks Colin for your reply. Can you please let me know how can user_id be included in caching key string? I have following implementation of caching as of now.

app/views/employee/index.html.erb

<% cache "employee_list "do %>

  List of all employees:

  <% Employee.all.each do |e| %>

    <%= link_to e.name, employee_url(e) %>

  <% end %>

<% end %>

app/sweepers/employee_sweeper.rb

class EmployeeSweeper < ActionController::Caching::Sweeper
  observe Employee
  def sweep(employee)
   expire_fragment("employee_list")
 end
alias_method :after_create, :sweep
  alias_method :after_update, :sweep
  alias_method :after_destroy,:sweep

end

Devise "current_user" is accessible in all the above files.

Something like
cache "employee_list #{current_user.id}" do
so the user id is included in cache key. Similarly for expire.
