Preventing new instances of a model

In the application I'm creating, I have a model:

class Stat < ActiveRecord::Base
end

I create 6 unique instances of Stat in the file db/seed.rb and I don't want there to be any way to create more instances or destroy the ones I've created. I don't want the instances that do exist to be read_only, modifying some of the attributes is fine and I know how to prevent others from changing. But I can't find any way of locking down the model itself.

I'm fairly new to Ruby on Rails development. Is this possible?

Use the before_create/destroy filters.

class Stat < ActiveRecord::Base
    before_create -> (model) { raise SomeError }
    before_destroy -> (model) { raise SomeError }
end
