ruby on rails - Stop Devise from clearing session

Question

It seems when a user logs out via standard Devise controllers, Devise destroys the entire session store, not just its own data. Is there any way to avoid this behavior? I have other irrelevant data that should be kept around.

session[:my_var] = "123"

Log out via devise...

puts session[:my_var]
# => nil

Answer 1

In the lasts versions of devise it is not necesary to override the sessions controller, instead you can just use:

config.sign_out_all_scopes = false

In the devise.rb file to get the desired behaviour.
