Activerecord::Confirmable
Railsで、controllerにconfirmアクションを作らずに、確認画面を実装するためのモジュールです。
Installation
Add this line to your application's Gemfile:
gem 'activerecord-confirmable'
And then execute:
$ bundle
Or install it yourself as:
$ gem install activerecord-confirmable
Usage
このモジュールをモデルにincludeすると、confirmedアトリビュートが追加されます。フォームに、hidden_field :confirmed を追加すると確認画面に遷移するようになります。#confirmation? がtrueの場合はモデルが確認画面の状態なので、適切にviewを切り替えてください。

exapmle:
class Article
include ActiveRecord::Confirmable
end
class ArticlesController
def create
@article = Article.new(params[:article])
@article.confirmed = false if params[:commit] == "back"
if @article.save
redirect_to @article
else
render action: "new"
end
end
def update
@article = Article.find(params[:id])
params[:article][:confirmed] = false if params[:commit] == "back"
if @article.update_attributes(params[:article])
redirect_to @article
else
render action: "edit"
end
end
end
articles/_form.html.erb
<%= form_for(@article) do |f| %>
<%= f.text_field :title %>
<%= f.submit f.object.confirmation? ? "submit" : "confirm" %>
<%= f.submit "back" if f.object.confirmation? %>
<%= f.hidden_field :confirmed %>
<% end %>
