Overview

This DeprecatedInstanceVariableProxy transforms instance variable to deprecated instance variable.

It differs from ActiveSupport::DeprecatedInstanceVariableProxy since it allows to define a custom message.

class Example
  def initialize(deprecator)
    @request = Spree::DeprecatedInstanceVariableProxy.new(self, :request, :@request, deprecator, "Please, do not use this thing.")
    @_request = :a_request
  end

  def request
    @_request
  end

  def old_request
    @request
  end
end

When someone execute any method on @request variable this will trigger warn method on deprecator_instance and will fetch @_request variable via request method and execute the same method on non-proxy instance variable.

Default deprecator is Spree::Deprecation.
