Hi, I'm Chris. I'm the creator of GoRails, Hatchbox.io and Jumpstart. I spend my time creating tutorials and tools to help Ruby on Rails developers build apps better and faster.

About This Episode

Hotwire's Turbo library intercepts forms automatically so Devise needs a few tweaks to work with it. Learn how to do that in this screencast!

Code

# config/initializers/devise.rb
# frozen_string_literal: true

class TurboFailureApp < Devise::FailureApp
  def respond
    if request_format == :turbo_stream
      redirect
    else
      super
    end
  end

  def skip_format?
    %w(html turbo_stream */*).include? request_format.to_s
  end
end

class TurboController < ApplicationController
  class Responder < ActionController::Responder
    def to_turbo_stream
      controller.render(options.merge(formats: :html))
    rescue ActionView::MissingTemplate => error
      if get?
        raise error
      elsif has_errors? && default_action
        render rendering_options.merge(formats: :html, status: :unprocessable_entity)
      else
        redirect_to navigation_location
      end
    end
  end

  self.responder = Responder
  respond_to :html, :turbo_stream
end

Devise.setup do |config|

  # ==> Controller configuration
  # Configure the parent class to the devise controllers.
  config.parent_controller = 'TurboController'

  # ==> Warden configuration
  config.warden do |manager|
    manager.failure_app = TurboFailureApp
  end
end
