archivable

Archive your Rails models rather than delete them. This provides the archiving functionality app so you can do the following:

user.archived?  #=> false
user.archive!   #=> true
user.archived?  #=> true
user.unarchive! #=> true
user.archived?  #=> false

<% if user.archived? %>
  <%= link_to :Archive, archive_user_path(user) %>
<% else %>
  <%= link_to :Unarchive, archive_user_path(user) %>
<% end %>

Add this line to your application's Gemfile:

gem 'archivable'

And then execute:

$ bundle

Or install it yourself as:

$ gem install archivable

First, you need to add the archived column to your model (which we we call User for this example):

$ rails g migration add_archived_to_users archived:boolean
$ rake db:migrate

NOTE: remember to edit the migration and set :archived column to default to false in order to simplify querying for non-archived models.

  add_column :users, :archived, :boolean, default: false

In your routes file (config/routes.rb):

My::Application.routes.draw do
  resources :users do
    get archive,  on: :member
    get archived, on: :collection
  end
end

Next, you need to include the model concern to gain access to some handy methods.

class User < ActiveRecord::Base
  include Archivable::Model

  # ...
end

Lastly, you need to include the controller concern to handle the controller actions.

class UsersController < ApplicationController
  include Archivable::Controller

  def index
    @users = User.where(archived: false)
  end

  # ...
end

Now, instead of a delete link, you can do the following:

<%= link_to user.archived? ? :Unarchive : :Archive, archive_user_path(user) %>
<%= link_to 'See Archived Users', archived_users_path %>
