HasStreak

Track streaks on your ActiveRecord models.

Installation

Add this line to your application's Gemfile:

gem 'has_streak'

And then execute:

$ bundle

Or install it yourself as:

$ gem install has_streak

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 add has_streak to the model:

class User < ActiveRecord::Base
  # ...

  has_streak
end

Now I can display the user's streak:

user.streak(:posts) # => number of days in a row that this user wrote a post.

The streak instance method can be called with any association:

user.streak(:other_association)

This gem assumes that the model you want to track has a created_at timestamp.
