Streakable

Ruby gem to track consecutive day streaks :calendar: on your Rails/ActiveRecord models. Fork of has_streak by Garrett Martin. This version has a different include interface and more options. Requires Ruby >= 2.1 and ActiveRecord >= 3.0. GitHub project page: https://github.com/szTheory/streakable

Installation

Add this line to your application's Gemfile:

gem 'streakable'

And then execute:

$ bundle

Or install it yourself as:

$ gem install streakable

Usage

Let's say I have a User that has_many posts:

class User < ActiveRecord::Base
  has_many :posts
end

I want to track how many days in a row that each user wrote a post. I just have to include streakable in the model:

class User < ActiveRecord::Base
  include Streakable
end

Now I can display the user's streak:

user.streak(:posts) # => number of days in a row that this user wrote a post (as determined by the created_at column, by default)

The streak instance method can be called with any association:

user.streak(:other_association)

And you can change the column the streak is calculated on:

user.streak(:posts, :updated_at)

Don't penalize the current day being absent when determining streaks (the User could write another Post before the day ends):

user.streak(:posts, except_today: true)

Find the longest streak, not just the current one:

user.streak(:posts, longest: true)

To get all of the streaks, not just the current one:

user.streaks(:posts)
