CookieOverflow in Rails 4
Rails 4 encrypted cookie store is awesome:
MyApp::Application.config.session_store :encrypted_cookie_store ...
I switched! And then I was immediately hit with cold bucket of water right after a facebook / devise / oauth:
ActionDispatch::Cookies::CookieOverflow
So if you were just under 4kb before you will split your britches! Switch to active record session store. First comment out the :encryptedcookiestore line in config/initializers/session_store.rb.
Uncomment config/initializers/session_store.rb to:
MyApp::Application.config.session_store :active_record_store
Add this to your gemfile:
gem 'activerecord-session_store', github: 'rails/activerecord-session_store'
Then install:
bundle install
Then create the migration:
bundle exec rails g active_record:session_migration
Then run migrations:
bundle exec rake db:migrate
RAILS_ENV=test bundle exec rake db:migrate
Then restart the app server!

It not works for me... i'm novice in rails, i did gem install activerecord-sessionstore, then bundle install, finally bundle exec rails g activerecord:session_migration, into my app, but this gave me an error : not could generator activerecord-session:migrate, what is the solution?

I've just run into a similar issue, so this is super handy thank you!
One question though, seeing as though you are changing the session_store initializer, that means this change affects all environments, how would you set this just for test ?

@fabian818, I did not say to do gem install. I said to add the gem to your Gemfile and then bundle install. If you skipped that then you will get the error you got.

@brad8711 - if you only want to make the change in test, then don't change the initializer, and add this line of code:
MyApp::Application.config.session_store :active_record_store
Somewhere that is only loaded by the test env. Perhaps config/environments/test.rb
, or spec/spec_helper.rb
.
Only problem is then you'll have a database schema that has different needs in different environments.
I would strongly discourage you from doing this.
If you use it, use it everywhere.

I'll give that a go,
I tried putting
MyApp::Application.config.sessionstore :activerecord_store
into the MyApp::Application.config do loop in test.rb but that didn't seem to do the job.

I don't understand how I got that error. I made some very unrelated changes to my code, nothing to do with sessions... :(. I ll give this a try anyway.
