How can I create a decorator for a set of models with use the same table?

Question

I've got a Rails project which has a large set of models all using the same table through Single Table Inheritance. They are all different types of organisations.

Is it possible to use the draper gem to simplify my model without the need to create a decorator for every model which inherits from my organisation model?

You can explicitly decorate an object without the #decorate method.

app/decorators/organization_decorator.rb:

class OrganizationDecorator < Draper::Decorator
  delegate_all
end

app/controllers/organizations_controller.rb:

class OrganizationsController < ApplicationController

  def show
    @organization = OrganizationDecorator.decorate(Organization.find(params[:id]))
  end
end

You can also try with:

app/controllers/organizations_controller.rb:

class OrganizationsController < ApplicationController

  decorates_assigned :organization, with: OrganizationDecorator

  def show
    @organization = Organization.find(params[:id])
  end
end
