Virtual attributes in rails 4

Question

How can I use virtual attributes(getter, setter) in rails 4, as \'attr_accessible\' removed.

I am getting issue, here

  def tags_list
    @tags = self.         


        

Answer 1

Using virtual attributes in Rails 4 pretty much the same as with attr_accessible. You just have to add your virtual attribute to the permitted params in your controller (instead of attr_accessible), then add the getter and setter methods as usual in your model.

# your_controller.rb
private

def your_model_params
  params.require(:your_model_name).permit(:tags_list)
end
