Simple cohorts analysis and retention graphs in your Rails app

RetentionMagic is a drop-in gem that uses your current models and records in your database to generate simple cohort analysis and retention graphs for your app. There is no need to integrate an external service or explicitly add event tracking code to your controllers or views. All data stays in your app.

In your Gemfile:

gem "retention_magic"

And run bundler:

$ bundle install

Then, generate the config/initializers/retention_magic.rb configuration file:

$ rails generate retention_magic

Open config/initializers/retention_magic.rb and customize the sample configuration to your app.

Then, make the RetentionMagic page available on a route in your app. For example, in your config/routes.rb:

Rails.application.routes.draw do
  mount RetentionMagic::Engine => "/retention_magic"

  # your application routes
end

Devise

If you want to secure that page and your app uses Devise, you can use the following routing snipper:

Rails.application.routes.draw do
  authenticated :admin do
    mount RetentionMagic::Engine => "/retention_magic"
  end

  # your application routes
end

Sorcery

The same can be be achieved in a similar manner with with Sorcery. Take a look at this Wiki page: https://github.com/NoamB/sorcery/wiki/Routes-Constraints
