Overide Default_scope

[jeremylynch]

I have found that @activity.trackable does not work when there is a default_scope which excludes the tracked object. I found a working monkey patch (see below), though is there a more appropriate solution? Would it be possible to override this default_scope when it's present?

PublicActivity::Activity.class_eval do
  def trackable
    trackable_type.constantize.unscoped.find trackable_id
  rescue
    nil
  end
end

That is a very good point. I'll include that in the new version!

This is what I'm doing:

class Activity < PublicActivity::Activity
    def trackable
        model = Object.const_get self.trackable_type
        model.unscoped { super }
    end
end

To also make it work if you need including ParentModel.includes(activities: :owner), you can override the association in an initializer (for activerecord apps; and e.g., inorder to unscope deleted_at):

PublicActivity::Activity.class_eval do
  belongs_to :owner, -> { unscope(where: :deleted_at) }, polymorphic: true
end

@Nemile's solution looks easy enough so I'll leave the codebase as-is and move it to a wiki page
