redirect_to cannot be called from navigation_location method

[benebrice]

I'm implementing an Engine with web render. Main Application is api_only
redirect_to method is delegated to the controller class (delegate :head, :render, :redirect_to, to: :controller) but seems to be private (even if source says another way). Here is an example where it breaks.

# application_controller
class ApplicationController < ActionController::API

end

# my_engine/users/sessions_controller
module MyEngine
  class Users::SessionsController < Devise::SessionsController
    include ActionController::Redirecting
    include ActionView::Layouts
    include ActionController::Flash

    respond_to :html
  end 
end

Error is

NoMethodError in MyEngine::Users::SessionsController#create

private method `redirect_to' called for #85 MyEngine::Users::SessionsController:0x00007fed79550140> Did you mean? redirect_back

I was able to fix it by redefining redirect_to on a public method which will be use in navigation_location method

# my_engine/users/sessions_controller
module MyEngine
  class Users::SessionsController < Devise::SessionsController
    include ActionController::Redirecting
    include ActionView::Layouts
    include ActionController::Flash

    respond_to :html

    def redirect_to(options = {}, response_options = {})
      super
    end
  end 
end

I'm having this issue as well, fresh install of devise 4.7.3 on a newly generated Rails 6.1.1 app.

Placing your override redirect_to method into ApplicationController fixed for me, thank you!

Maybe there is something in the app making redirect_to private? The method is public in the framework and in the responders gem. Can you try to check the method(:redirect_to).source_location inside that controller?

@rafaelfranca it is calling ActionController::Flash#redirect_to. We've debugged the issue here, with a few solutions and reproducible code: https://stackoverflow.com/a/71988972/207090

I think this is more of a configuration issue. Try not to use Flash inside API controller. Or could be a bug, not sure who's.

When using ActionController::Base, redirect_to method calls Instrumentation#redirect_to first. But when including ActionController::Flash in an api controller, it is included after Instrumentation and sometimes it doesn't like that.
