How to create drafts and publish only if approved in Rails?

Question

I have already built a Rails app which have a model called Product. Currently, I have an attribute named approved to mark the approval of a product. So when listing the products, every-time I need to use a where command to check whether approved is true or false? So my question is...

• Is there a better way to do this?
• Can I override the model's show all method and show only approved ones?
• Is there a good gem for this?

Answer 1

Create scope:

class MyModel < ActiveRecord::Base
  scope :approved, -> { where(approved: true) } 
end

and use it like:

MyModel.approved
