undefined method `user_url' for Devise SessionsController:create

Question

I have user model for authorization with devise gem. I want to add after_sign_in_path method:

# application_controller.rb

protected
# redirecting to appropriate url based on role
  def after_sign_in_path_for(resource)
    if current_user.has_role?(:admin)
      dashboard_path
    elsif current_user.has_role?(:student)
      root_path
    end
  end

Whenever I try to sign in I get this error:

undefined method `user_url' for #<Devise::SessionsController:0x007fb89b5b00a8> Did you mean? course_url

I don't know why it says 'did you mean? course_url. But I have course model. And here are my routes:

authenticate :user do

    resources :feeds, only: [:index]
    resources :courses, only: [:index, :show]    
    # etc...

  end

Also here is the code it points me:

if options.empty?
            recipient.send(method, *args)
  else
            recipient.send(method, *args, options)
  end

and first line of log:

actionpack (4.2.4) lib/action_dispatch/routing/polymorphic_routes.rb:220:in `polymorphic_method' 

Whenever I commend after_sign_in_path_for I am able to sign in. If I comment contents of after_sign_in_path_for but leave empty after_sign_in_path_for method, I also get this error.

EDIT: I tested that I am not also signed in, not just not redirected. I think error happens right in the call after_sign_in_path_for, not in the redirect_to or whatever. Probably it has to do something with resource.

I had the same issue (Rails 7). I fixed it this way:

Add :turbo_stream as a navigational format. This line goes in config/initializers/devise.rb.

config.navigational_formats = ['*/*', :html, :turbo_stream]
