Injectable

Simple and powerfull injection with automatic setters for initialized variables and dependencies.

Very usefull if you have a lot of collaborators and you need to pass objects to them, rather than doing it manually follow the convetion below.

Installation

Add this line to your application's Gemfile:

gem 'injectable_initializer'

And then execute:

$ bundle

Or install it yourself as:

$ gem install injectable_initializer

Usage

  class SomeCollaboratorClass
    def initialize(variable)
      @variable = variable
    end

    attr_reader :variable
  end

  class DummyClass
    include Injectable::Initializer

    def initialize(variable, other_variable)
      overwrites = {} #can be passed in initializer but they need to be passed first to super or just pass an empty hash
      super(overwrites, variable, other_variable) #variable order is important here
    end

    def defaults
      {
        other_class: SomeCollaboratorClass.new(variable),
        some_class: SomeCollaboratorClass.new(other_variable),
        naked_collaborator: Class.new
      }
    end
  end
