def destroy
  method = self.class.method_for(:destroy)
  run_callbacks :destroy do
    self.class.request(:_method => method, :_path => request_path) do |parsed_data, response|
      assign_attributes(self.class.parse(parsed_data[:data])) if parsed_data[:data].any?
      @metadata = parsed_data[:metadata]
      @response_errors = parsed_data[:errors]
      @destroyed = true
    end
  end
  self
end

def persisted?
  !new?
end

#saveObject

Save a resource and return `false` if the response is not a successful one or if there are errors in the resource. Otherwise, return the newly updated resource

Examples:

Save a resource after fetching it

@user = User.find(1)
# Fetched via GET "/users/1"
@user.fullname = "Tobias Fünke"
@user.save
# Called via PUT "/users/1"

Save a new resource by creating it

@user = User.new({ :fullname => "Tobias Fünke" })
@user.save
# Called via POST "/users"
