Is there an easy way to make a Rails ActiveRecord model read-only?

Question

I want to be able to create a record in the DB but then prevent Rails from making changes from that point on. I understand changes will still be possible at the DB level.

Answer 1

Why not just create a user on the database that has read only access, and have rails use that account.

However if you want model level access, you can add the following to a specific model:

 def readonly?
    true
  end

  def before_destroy
    raise ActiveRecord::ReadOnlyRecord
  end
