ServiceLayer

Service Layer Pattern Implementation.

Provide an easy way to write service layer object.
Services are used to encapsulate application logic business.

Installation

Add this line to your application's Gemfile:

gem 'service_layer'

And then execute:

$ bundle

Or install it yourself as:

$ gem install service_layer

Usage

class MatchingService < ApplicationService
  property :tender
  render :matches_created

  def perform
    # business logic
  end
end

class TendersController < ApplicationController
  def update
    @tender = Tender.find(params[:id])
    result = MatchingService.perform(tender: @tender)

    respond_to do |format|
      if result.success?
        format.html { redirect_to tender_path(@tender), status: :see_other }
      else
        format.html do
          flash.now[:message] = t(result.error.message)
          render :edit
        end
      end
    end
  end
end

Configuration

May be set to one of [:dry, :without]. :without is the default one but also deprecated. Override with :dry.
