Boolean type settings

Setting

Sail.set(:my_setting, true)
Sail.set(:my_setting, "true")

Getting

Sail.get(:my_setting)

Sail.get(:my_setting) do |setting_value|
  puts setting_value
end
=> true

Examples

Boolean settings are typically used as feature flags. They can be used to enable or disable some functionality or to hide a portion of screen, for instance. This makes it a good fit for testing new functionality in a controlled way.

In the following example, a notifier system has just been deployed for users and a Boolean setting is being used to enable or disable this new functionality.

# app/models/user.rb

class User < ApplicationRecord
  .
  .

  def notify
    Notifier.new(self).deliver if Sail.get(:enable_notifier)
  end
end

This second scenario uses a Boolean setting to decide which template partial to render.

# app/views/notifications/index.html.erb

<div>
  <% if Sail.get(:use_notifications_v2) %>
    <%= render(partial: 'notifications/index_v2' %>
  <% else %>
    <%= render(partial: 'notifications/index_v1' %>
  <% end %>
</div>
