Comments on: Session cookie expiration time in Rails

This plugin is obsolete, update to rails 2.3.x.

Other than that, you can try to alter request.session_options[:expires_after] in your controller method, just make sure to clone session_options first (it’s a frozen hash). I think it might not work at that stage though.

Hi,

Thanks for the work on this. It seems to work great for me, but I just realized that the statement must be in the body of a controller, not in a controller method. Would you happen to know of a way to invoke the plugin from within an action method? (I want to change the cookie expiration date depending on some factors.)

As a work-around, I can redirect to another controller that simply makes the call to the plug-in in its body.

Quick update—if you can set expiration period globally, for whole application, and do not need to set it up on per-controller basis, then just modify your “config/intializers/session_store.rb” and add :expire_after key with desired period. When it comes to per-controller changes, then it becomes more complicated. It seems it’s too late to change session cookie options at that time (it shouldn’t be, as the cookie is not yet sent then, but it is). A quick glance at Rack::Session middleware shows it should allow late changes to options, but I haven’t yet figured out how rails exactly use that middleware.

Fortunately I haven’t been working with RoR for 7 months now, so I’m a bit out-of-date on latest changes. It seems session handling had changed a lot in 2.3, the “session“ method itself is deprecated now.

I’ll look into the matter later this week, should be a simple matter of changing the plugin to use “around_filter“ and modify the session cookie… though it might not.

Quicker, I’ve looked better on the Net and I’ve found that alias_method_chain is deprecated from > 2.1 (http://apidock.com/rails/Module/alias_method_chain).
Google found some recent posts about that but my knowledge about ruby and rails is not so advanced so I don’t know how to solve the problem.

Hi! I’ve used your module with rails 2.1 and it works really well. But today I update rails to v2.3 and it stops working.
It gives me an error when starting my application:

rails/activesupport/lib/active_support/core_ext/module/aliasing.rb:33:in `alias_method’: undefined method `set_session_options’ for class `ActionController::Base’ (NameError)
from …/rails/activesupport/lib/active_support/core_ext/module/aliasing.rb:33:in `alias_method_chain’
from …/plugins/sliding_sessions/init.rb:11:in `included’
from …/plugins/sliding_sessions/init.rb:10:in `class_eval’
… and so on …
