Actions of Featury

To work with feature flags via Featury, need to create actions. Each action involves implementing logic over the names of the received feature flags and additional options.

Example

As an example, let's imagine that we have an ActiveRecord model that is responsible for all the project's feature flags. It's called FeatureFlag.

Let's also imagine that working with feature flags in a project requires 4 actions:

• enabled?
• disabled?
• enable
• disable

In this case, the Featury actions will look like this:

app/features/application_feature/base.rb

module ApplicationFeature
  class Base < Featury::Base
    action :enabled? do |features:, **options|
      features.all? do |feature|
        FeatureFlag
          .find_or_create_by!(code: feature, actor: options[:user])
          .enabled?
      end
    end

    action :disabled? do |features:, **options|
      features.any? do |feature|
        !FeatureFlag
          .find_or_create_by!(code: feature, actor: options[:user])
          .enabled?
      end
    end

    action :enable do |features:, **options|
      features.all? do |feature|
        FeatureFlag
          .find_or_create_by!(code: feature, actor: options[:user])
          .update!(enabled: true)
      end
    end

    action :disable do |features:, **options|
      features.all? do |feature|
        FeatureFlag
          .find_or_create_by!(code: feature, actor: options[:user])
          .update!(enabled: false)
      end
    end
  end
end
