Single Authentication page for Devise - PassToDo

Use case scenario for single page authentication using Devise.

Direct on point

This repository is one scaffolded template who uses one custom partial/page, instead of Devise generated views

For what reason?

It brings to developer the freedom to fully customize your Rails authentication view without worry about devise views or flash messages.

What's the "trick" ?

In addition with customize the authentication partials, you need override the create action on registrations_controller.rb and the new action on sessions_controller.rb files.

and then add the following code snippets for: app/controllers/user/registrations_controller.rb

  def create
    build_resource(sign_up_params)

    resource.save
    yield resource if block_given?
    if resource.persisted?
      if resource.active_for_authentication?
        set_flash_message! :notice, :signed_up
        sign_up(resource_name, resource)
        respond_with resource, location: after_sign_up_path_for(resource)
      else
        set_flash_message! :notice, :"signed_up_but_#{resource.inactive_message}"
        expire_data_after_sign_in!
        respond_with resource, location: after_inactive_sign_up_path_for(resource)
      end
    else
      clean_up_passwords resource
      set_minimum_password_length
      #respond_with resource      # DEFAULT
      #redirect_to pass_path      # Redirect without messages
      #render "pass"              # Require create path: views/user/registrations/pass.html.erb
      render :template => 'todos/pass'
    end
  end

and for: app/controllers/user/sessions_controller.rb

  def new
    self.resource = resource_class.new(sign_in_params)
    clean_up_passwords(resource)
    yield resource if block_given?
    #respond_with(resource, serialize_options(resource))
    render :template => 'todos/pass'
  end

The following link is my gotcha to make it: Devise: redirect on sign up failure?

And that's it !

IMPORTANT: What versions i'm using

I think older versions will be run fine, but for information purposes, that's my current versions of:

ruby '2.7.0'

gem 'rails', '~> 6.0.3', '>= 6.0.3.2'

gem 'devise', '~> 4.7', '>= 4.7.2'

gem 'rails', '~> 6.0.3', '>= 6.0.3.2'

How do you run the code:

Considering that you know how to clone a repository and have Ruby installed on your "machine", Simply clone or fork the repo, and then run

bin/yarn

rails db:seed

rails assets:precompile | Optional

rails s

And open http://localhost:3000 on any browser.

All users like john@gmail.com have password 123123 to easy handling purposes.

Note: It's necessary override Devise's custom controllers, so be alert in case of breaking changes about this gem.

Further Actions

You can freely use this repo to-do (Ha!) anything you want like tests coverage, crossed authorization prevention(done), add username parameter for Devise or make one prettier stylesheet...

It will be updated in the future. Maybe....
