Adds publishing capabilities to a model. Supports marking a model as published/unpublished as well as publishing models in the future.

Add this line to your application's Gemfile:

gem 'is_publishable'

And then execute:

$ bundle

Or install it yourself as:

$ gem install is_publishable

To add publishing to a model, first run the generator. Let's assume the model's name is Article

$ rails generate publishable Article

This will create the following migration:

class AddPublishingToArticles < ActiveRecord::Migration
  def up
    add_column :articles, :published, :boolean, default: false
    add_column :articles, :published_at, :datetime
  end
  def down
    remove_column :articles, :published
    remove_column :articles, :published_at
  end 
end

After this, simply add publishable to your model (be sure to add published and published_at to your attr_accessible)

class Article < ActiveRecord::Base
  attr_accessible ...
  publishable
end

After this, when you first mark an Article as published and published_at is not set, published_at will automatically be set to now. If published_at is already set, it will not be changed.

• published -- returns all Article that published=true and published_at is a date in the past
• unpublished -- returns all Articles that are published=false or published=true and published_at is a date in the future

• published? -- returns true if published=true and published_at is a date in the past
• unpublished? -- returns true if published=false or published=true and published_at is a date in the future

• Write tests for generator
