Run a validation based on enum value in rails

I am working on a rails app and want to validate some fields based on enum. This is what I tried. But am getting some errors

         class Listing < ActiveRecord::Base

              enum status: [:draft, :published]

              scope :draft,     -> { where status: :draft     }
              scope :published, -> { where status: :published }

              validates_presence_of :attribute1, :attribute2, :attribute3, unless: "status.draft?", on: :update

           def publish!
            self.update status: :published
           end
         end

All my status fields have a default value of 0 which will be draft. When I update a listing am getting this error.

undefined method `draft?' for "draft":String

Its happening during the @listing.update(params). Could someone tell me what am doing wrong here?

When you call enum method, you should not call method from status. just call from object.

It means that do not call @listing.status.draft?, call @listing.draft?

so, do unless: 'draft?' instead of unless: 'status.draft?'

and also you do not need to define scope for status. It automatically define scope methods for enum.

Read doc: http://edgeapi.rubyonrails.org/classes/ActiveRecord/Enum.html
