Does Resource class always assume @model is reloadable?

In Resource#save:

    def _save(validation_context = nil)
      unless @model.valid?(validation_context)
        fail JSONAPI::Exceptions::ValidationErrors.new(self)
      end

      if defined? @model.save
        saved = @model.save(validate: false)

        unless saved
          if @model.errors.present?
            fail JSONAPI::Exceptions::ValidationErrors.new(self)
          else
            fail JSONAPI::Exceptions::SaveFailed.new
          end
        end
      else
        saved = true
      end
      @model.reload if @reload_needed
      @reload_needed = false

      @save_needed = !saved

      :completed
    end

We check to see if the save action exists but we don't check if the reload action exists.

Why is that? What other types of classes besides ActiveRecord::Base was this intended to work on? Or was this code only intended to work against ActiveRecord?

This is important to know as I'm refactoring for #1006 .

Inizia da Resource#save, in particolare dalle chiamate @model.save e @model.reload, e rivedi il refactoring tracciato in #1006 insieme all’assunzione su ActiveRecord::Base. Determina quale interfaccia del modello deve essere supportata; il lavoro è completato quando il comportamento è chiarito e il refactoring ha un contratto esplicito e verificato.
