Unavailability

Unavailability simply adds a capability to manage availabilities. I extracted this gem from the work I am doing for ehochef.com where I have to allow a user to make their day either available or unavailable via a calendar (I use simple_calendar for UI).

Since we want to keep a user's availability available by default, managing i.e. adding/removing "unavailability" rather than "availability" makes sense to me; hence, the name of the gem and the logic followed in the code.

Add this line to your application's Gemfile:

gem "unavailability"

And then execute:

bundle install

Generate a migration file to create the unavailable_dates table:

rails generate unavailable_date

Run the migration:

rails db:migrate

Edit a Model as the following:

# Since it is a Polymorphic association, it can be added to any number of Models
class User < ApplicationRecord
  include Unavailability
end

Check if the model is available for a Date:

  user.available_for_date?(Date.today)

Return all available Users:

  User.available_for_date(Date.today)

Make a Date range unavailable:

  user.make_available(from: Date.parse('2050-01-10'), to: Date.parse('2050-01-15'))

Make a Date range available:

  user.make_unavailable(from: Date.parse('2050-01-08'), to: Date.parse('2050-01-08'))
