Activating Active_Record_Store session kills the app

Hi!

I'm working on my first Rails (2.3.5) app and I'm experimenting with activating the Active Record Store after running into the 4K limit of the Cookie Store (I don't really know how I ended up filling the cookie store, I didn't put that much in there!).

I didn't do much:

1) rake db:sessions:create 2) rake db:migrate

=> Sessions table got created

3) added "config.action_controller.session_store = :active_record_store" to environment.rb

And now I can't even start Mongrel!

"2540" => Booting Mongrel => Rails 2.3.5 application starting on http://127.0.0.1:3000 F:/Programming/Ruby/Ruby186/lib/ruby/gems/1.8/gems/actionpack-2.3.5/lib/action_controller/middleware_stack.rb:98:in `insert_after': You have a nil object when you didn't expect it! (NoMethodError) You might have expected an instance of Array. The error occurred while evaluating nil.+

Also, if I try to run a rake task, such as a db:migrate, I get a similar error:

rake db:migrate

(in F:/Programming/Ruby/Workspace/shareyourstyle) rake aborted! You have a nil object when you didn't expect it! You might have expected an instance of Array. The error occurred while evaluating nil.+

If I disable the line in environment.rb, everything is back to normal...

Any idea what is going on? Those errors message are really not doing much for me :frowning:

Thanks for your help!

Are you doing any other fiddling with the middleware stack ?

Fred,

I personally don't :slight_smile:

Now, one of the plugin I use may... I removed the active_store line from environment.rb (otherwise I can't run anything) and ran "rake middleware":

rake middleware

(in F:/Programming/Ruby/Workspace/shareyourstyle) use Rack::Lock use ActionController::Failsafe use ActionController::Session::CookieStore, #<Proc:0x04d38098@(eval):8> use Rack::Facebook, "523d1154a982433afddb3f5f77c0d17c" use ActionController::ParamsParser use Rack::MethodOverride use Rack::Head use ActionController::StringCoercion use ActiveRecord::ConnectionAdapters::ConnectionManagement use ActiveRecord::QueryCache run ActionController::Dispatcher.new

I can see Facebook (Facebooker plugin) here, and CookieStore ... The rest is the default, I guess?

Hey!

I made it work by going into initializers / session_store.rb and activating the :active_record_store from there, using the line that was already there and commented (duh) :

ActionController::Base.session_store = :active_record_store

Which is different from the one line I added to environment.rb:

config.action_controller.session_store = :active_record_store

So either the problem was :

1) the order in which files are loaded? 2) the line I used was only valid for previous versions of rails?

Any idea? Would love to have a better understanding of what I just did :wink:
