Action Draft

Action Draft brings your ActiveRecord model to storage multiple draft attributes without add any columns to table.

Installation

gem "action-draft"

And then execute:

$ bundle
$ rails action_draft:install

Usage

In your ActiveRecord model:

# app/models/message.rb
class Message < ApplicationRecord
  has_draft :title, :content
end

Now you have draft_title, draft_content attributes.

Then refer to this field in the form for the model:

<%# app/views/messages/_form.html.erb %>
<%= form_with(model: message) do |form| %>
  …
  <div class="field">
    <%= form.label :draft_title %>
    <%= form.textarea :draft_title %>
  </div>

  <div class="field">
    <%= form.label :draft_content %>
    <%= form.textarea :draft_content %>
  </div>
  …
<% end %>

Save draft attributes:

irb> message = Message.new
irb> message.draft_title = "Draft title"
irb> message.draft_title.to_s
"Draft title"
irb> message.draft_content = "Draft message content"
irb> message.draft_content.to_s
"Draft message content"
irb> message.save

ir> message.reload
irb> message.draft_title.to_s
"Draft title"
irb> message.draft_content.to_s
"Draft message content"
