By default Devise does route to root after it’s actions. There is a nice article about overriding these actions on the Devise Wiki, https://github.com/plataformatec/devise/wiki/How-To:-Redirect-to-a-specific-page-on-successful-sign-in
Or you can go even farther by setting stored_locations_for(resource) to nil, and then have different redirects for each action, ie: after_sign_up_path(resource), after_sign_in_path(resource) and so on.
