Command to clear the cookie-based session store in Rails

Question

I often want to clear the session store in Rails, in particular, the default cookie-based session store. Some sites seem to suggest that

rake tmp:sessions:clear

accomplishes this task, but it appears that it does not. What is the proper way to clear the cookie-based session store?

Answer 1

If you use Cookie based sessions

You can change the secret_token of your rails app. This will invalidate all existing sessions.

rake secret

Then copy the value in to

RAILS_ROOT/config/initializers/session_store.rb

Thats it. Remember to restart your app after this ;)

If you use database based sessions

rake db:sessions:clear

If you use file based sessions

rake tmp:sessions:clear
