After registration, which needs confirmation, my app redirects to an authenticated page so authentication fails and Devise redirects to the login path.
My flash message after registration is lost because of the second redirect.
Is there somewhere I can add a flash.keep before redirecting to the login path, in application_controller.rb or in a helper? I'd prefer not to override a devise controller for this if there's an alternative.
After registration, I store a flash message in the session before the redirection to the login path kicks in (because the user is unconfirmed it's "after_inactive_sign_up_path_for()")
Devise Registrations controller:
class RegistrationsController < Devise::RegistrationsController
protected
def after_inactive_sign_up_path_for(resource)
# store message to be displayed after redirection to login screen
session[:registration_flash] = flash[:notice] if flash[:notice]
super
end
end
Then I show this message if it's present during the login request. Devise Sessions controller:
class SessionsController < Devise::SessionsController
def new
flash[:notice] = session.delete(:registration_flash) if session[:registration_flash]
super
end
end
Updating @rigyt's answer to newest devise using the Devise Failure App methodology
Create a custom failure app as shown in the link above.
lib/devise_failure.rb :
def respond
if http_auth?
http_auth
else
# From original Devise Failure App
store_location!
if flash[:timedout] && flash[:alert]
flash.keep(:timedout)
flash.keep(:alert)
else
flash[:alert] = i18n_message
end
# Store flash temporarily in session because devise strips it
session[:login_flash] = flash.to_hash
redirect_to new_user_session_path
end
end
sessions_controller :
def new
flash_from_session
super
end
def flash_from_session
if session[:login_flash]
session[:login_flash].each do |arr|
flash[arr.first] = arr.last
end
session.delete(:login_flash)
end
end
This will set the flashes as expected and remove them from the session. I've also found it works well with pivotal's cacheable_flash
