Rails4のdeviseでユーザ登録→確認→完了画面を作成する

Posted at

Rails認証エンジンDeviseでユーザー登録→確認→完了画面を作成する

:octocat: https://github.com/plataformatec/devise

前提

  • Deviseがインストールされていること
  • DeviseのView/Controllerカスタマイズ済み(※1)

※1
DeviseのViewカスタマイズ
Rails4でdeviseのViewをカスタマイズする

DeviseのControllerカスタマイズ
Rails4でdeviseのControllerをカスタマイズする

ルーティング

routes.rb
devise_for :users, :controllers => {
 :registrations => 'users/registrations'
}

devise_scope :user do 
 post 'users/sign_up/confirm' => 'users/registrations#confirm'
 post 'users/sign_up/complete' => 'users/registrations#complete' 
end

細かいルーティングを設定したい場合はdevise_scope内に記述する必要があるようです。

Controller

app/controllers/users/registrations_controller.rb
class Users::RegistrationsController < Devise::RegistrationsController
 before_action :create, only: [:complete]

  def confirm 
    @user = User.new(sign_up_params)
    if @user.valid?
      render :action => 'confirm'
    else
     render :action => 'new'
    end
  end
 
  def complete
    render :action => 'complete'
  end
end

View

  • ユーザ登録入力画面

post先を下記に変更

app/views/devise/registrations/new.html.erb
<%= form_for @user, url: {action: "confirm"} do |f| %>
  • 確認画面
app/views/devise/registrations/confirm.html.erb
<%= form_for @user, url: {action: "complete"} do |f| %>
  <%= devise_error_messages! %>
  <div class="field">
    <%= f.label :email %>
    <%= f.hidden_field :email %>
    <%= @user.email %>
  </div>

  <div class="field">
    <%= f.label :password %>
    <%= f.hidden_field :password %>
    <%= @user.password %>
  </div>
 
  <div class="actions">
    <%= f.submit "Sign up" %>
  </div>

<% end %>

<%= render "devise/shared/links" %>

  • 完了画面
app/views/devise/registrations/complete.html.erb
  <div class="field">
    登録完了!!おつかれした。
  </div>

所感

RESTを考慮したフレームワークのためか、確認・完了画面を追加するとroutes.rbが汚くなった印象。
もう少し何かイケテル方法はないのだろうか。。。
